C GX420t / GX430t User Guide 8/4/10 Getting Started 19 Loading Transfer Ribbon Loading Transfer Ribbon Transfer ribbons come in several varieties and in some cases colors to match your application needs. Genuine Zebra® transfer ribbons are specifically designed for your printer and Zebra brand media. Using non-Zebra media or ribbons not approved for use in your Zebra® printer may damage your printer or printhead. • The media and ribbon types should be matched to provide you with optimal print results. • Always use ribbon that is wider than the media to protect the printhead from wear. • For direct thermal printing, do not load ribbon in the printer. Your printer needs to use Zebra® Uni-Ribbon™ (universal ribbon). Uni-Ribbons have a ribbon out trailer (reflector) to stop printing when empty. Zebra® Uni-Ribbon™ will work on older model Zebra® desktop printers too. Uni-Ribbons are identified with a color coded leader. • Blue - Performance Wax (5319) • Silver - Premium Wax/Resin (3200) • Gold - Performance Resin (5095) for synthetics (6 ips max. speed) and coated paper (4 ips max. speed) • Red - Premium Resin (5100) for synthetics (4 ips max. speed) Before following these steps, prepare the ribbon by removing its wrapping and pulling its adhesive strip free. Notch Right Side (printer and roll) Adhesive Strip See Ribbon Overview on page 42 for more information on ribbon use. Important • DO NOT USE early model desktop printer ribbon cores! The older ribbon cores can be identified by notches on only one side of the ribbon core. These older cores are too large and will cause take-up spool to bind. Note • DO NOT USE ribbon cores with damaged notches - rounded, frayed, smashed, etc. The core notches should be square to lock the core on the spindle or the core may slip causing ribbon wrinkle, poor end of ribbon sensing or other intermittent failures. 8/4/10 GX420t / GX430t User Guide 980612-001 Rev. C 20 Getting Started Loading Transfer Ribbon 1. With the printer open, place a new ribbon roll on printer’s lower ribbon supply spindles. Rotate the roll until the notches align and lock into the left side of the supply hub. 2. Place an empty ribbon core on printer’s take-up spindles. Rotate the ribbon core until the notches align and lock into the left side of the take-up hub. You can find your first ribbon take-up core in the packing box. Subsequently, use the empty supply core to take up the next roll of ribbon. 980612-001 Rev. C GX420t / GX430t User Guide 8/4/10 Getting Started 21 Loading Transfer Ribbon 3. Pull the transfer ribbon’s leader off the roll and attach it with the adhesive strip on the leader to the empty ribbon core on the supply spindle.

C 24 Getting Started Pre-install Windows® Printer Drivers Pre-install Windows® Printer Drivers Zebra is changing the way you install and use your printer with your Windows based PC systems. We recommend that at minimum, the ZebraDesigner™ Windows® driver be pre installed to take advantage of the advancements in ease of use and simplicity of the Windows operating systems since the release of Windows XP® SP2. Zebra provides the Zebra Setup Utilities (ZSU); a suite of Zebra® printer drivers, utilities, and communications and installation tools for use with most Windows PC operating systems. Zebra Setup Utilities and Zebra Windows printer drivers are available on the user’s CD and the Zebra web site ( zebra.com) for latest versions. ZebraDesigner™ Driver and Zebra Setup Utilities (includes the driver): Supports Windows 7®, Windows Vista®, Windows XP®, Windows® 2000®, Windows Server® 2008, and Windows Server® 2003 operating systems. The driver supports 32 bit and 64 bit Windows operating systems and is Microsoft Certified. Zebra Setup Utilities and the ZebraDesigner driver support the following G-Series printer communication interfaces: USB, parallel, serial, Wired and Wireless Ethernet and Bluetooth (using a Bluetooth virtual printer port). Install the Zebra Setup Utilities before applying power to the printer connected to the PC (running a Zebra driver supported Windows operating system). The Zebra Setup Utility will prompt you to apply the printer power. Continue to follow the instructions to complete your printer installation. Plug’N’Play (PnP) Printer Detection and Windows® operating systems More recent Windows operating systems automatically detect the printer when it is connected via the USB interface. Depending on the hardware configuration and the Windows version, your printer may be Plug-and-Play (PnP) detected when connecting to the USB, parallel, or serial port interfaces. The printer drivers do not support serial port PnP installation at this time.The printer’s PC interface configuration for the parallel port must support and have bidirectional communications for PnP operations. The operating system automatically starts a “Add new hardware’ wizard when connecting the printer for the first time to the PC. If you have pre-loaded the driver suite with the Zebra Setup Utility, then the printer driver will automatically install. Go to your Windows printer directory and right-click and select ‘Properties’. Click on the ‘Print test page’ button to verify a successful installation. The Windows operating system will detect and re-link a previously installed printer if it is reconnected to the USB interface or if printer power is turned on after the PC has finished its restart of the operating system. Ignore the new device detected warnings and close the Task bar prompts. Wait several seconds for the operating system to match the printer to the driver software. The warnings will quit and the printer now should be ready to begin printing. Universal Serial Bus (USB) Device Communications The printer is a terminal device (not a host or hub) when using a USB interface. You can refer to the USB Specification for details regarding this interface. Note • Scanners, scales or other data input (terminal) devices must use the serial port (not the USB port) to send data to the printer. 980612-001 Rev. C GX420t / GX430t User Guide 8/4/10 Getting Started 25 Pre-install Windows® Printer Drivers Serial Port and Windows® operating systems The Windows operating system default settings for the serial port communication closely match the printer’s defaults settings with one exception; the data Flow Control settings. The Windows default data Flow Control setting is NONE. The G-Series printer requires data Flow Control set to Hardware. Note • The G-Series™ printer does not support Windows® Serial Port Plug and Play (PnP) device detection at this time. Ethernet This printer option has a variety of methods and utilities to assist with printer connection to a network (WAN or LAN) and to configure Wired and Wireless (WiFi) printers. The Zebra Setup Utility configuration wizards support creating a connection to the printer on a shared network with Windows based systems by using the printer’s IP address. The printer includes internal Web pages to provide easy access to printer and network configuration. The web pages are accessible via the printers IP address using any web browser. The free version of ZebraNet™ Bridge software allows you to centrally deploy, manage, and monitor your Zebra® printers with automatic Zebra® printer discovery up to 3 printers from a single PC screen anywhere on your global network. ZebraNet™ Bridge Enterprise is available for purchase to manage larger numbers of Zebra® printers. 8/4/10 GX420t / GX430t User Guide 980612-001 Rev. C 26 Getting Started Connecting your Printer to a Computer Connecting your Printer to a Computer The Zebra® G-Series™ printers support a variety of interface options and configurations. These include: Universal Serial Bus (USB) interface, RS232 Serial, Parallel (IEEE 1284.4) and 10/100 Ethernet. • USB, Serial and Parallel • Optional: USB, Serial, and Ethernet (Wired) • Optional: USB, Serial, and Ethernet (Wireless-WiFi) with LCD display • Optional: USB, Serial, and Bluetooth with LCD display The Zebra Setup Utility is designed to assist you with installing these interfaces. The cabling and unique parameters for each of these physical printer communication interfaces is discussed in the following pages to assist you with making configuration setup choices prior to and immediately following applying power. The Zebra Setup Utilities configuration wizards will instruct you to turn the printer’s power on at the appropriate time to complete the installation of your printer. For Connecting to Wireless Communication Interfaces: • Wi-Fi (Ethernet), see the ZebraNet® 10/100 Internal Print Server manual. • Bluetooth, see the Bluetooth Option on page 67. Caution • Keep the power switch in the OFF position when attaching the interface cable. The power cord must be inserted into the power supply and the power receptacle on the back of the printer before connecting or disconnecting the communications cables. Interface Cable Requirements Data cables must be of fully shielded construction and fitted with metal or metallized connector shells. Shielded cables and connectors are required to prevent radiation and reception of electrical noise. To minimize electrical noise pickup in the cable: • Keep data cables as short as possible (6 foot [1.83 m] recommended). • Do not tightly bundle the data cables with power cords. • Do not tie the data cables to power wire conduits. . Important • This printer complies with FCC “Rules and Regulations,” Part 15, for Class B Equipment, using fully shielded data cables. Use of un-shielded cables may increase radiated emissions above the Class B limits. 980612-001 Rev. C GX420t / GX430t User Guide 8/4/10 Getting Started 27 Connecting your Printer to a Computer USB Interface Requirements Universal Serial Bus (version 2.0 compliant) provides a fast interface that is compatible with your existing PC hardware. USB’s “plug and play” design makes installation easy. Multiple printers can share a single USB port/hub. When using a USB cable (not supplied with your printer), verify that the cable or cable packaging bears the “Certified USB™” mark (see below) to guarantee USB 2.0 compliance. . USB Cable 8/4/10 GX420t / GX430t User Guide 980612-001 Rev. C 28 Getting Started Connecting your Printer to a Computer Serial Communications The printer automatically detects and switches the serial port to match common serial port cabling and signal connection configurations for DTE and DCE communications. The required cable must have a nine-pin “D” type (DB-9P) male connector on one end which plugs into the mating (DB-9S) serial port located on the back of the printer. The other end of this signal interface cable connects to a serial port on the host computer. This allows for the use of two common cable types and drop-in replacement for Zebra and other printer models. Zebra® printers use a Null Modem (cross-over) cable. Early models of Zebra® printers (a DCE device) running the EPL programming utilized a straight through (no cross-over) signal connections cable. For pinout information, refer to Appendix A. The serial port communication settings between the printer and host (typically a PC) must match for reliable communication. The Bits per second (or Baud rate) and Flow control are the most common settings that get changed. The host (typically a Windows PC) needs to have the data Flow control changed to match the printer’s default communication method: Hardware and is noted by the Host Handshake setting DTR/Xon/Xoff for legacy printer. This combined hardware (DTR) and software (Xon/Xoff) mode may need to change depending upon the non-Zebra application software and the serial cable variation in use. Serial communications between the printer and the host computer can be set by: • Autobaud synchronization • ZPL programming ^SC command • EPL programming Y command • Resetting the printer to its default printer configuration. Autobaud Autobaud synchronization allows the printer to automatically match the communication parameters of the host computer. To autobaud: 1. Press and hold the feed button until the green status LED flashes once, twice, and then three times. 2. While the status LED flashes, send the ^XA^XZ command sequence to the printer. 3. When the printer and host are synchronized, the LED changes to solid green. (No labels will print during autobaud synchronization.) ZPL ^SC Command Use the Set Communications (^SC) command to change the communications settings on the printer. 1. With the host computer set at the same communications settings as the printer, send the ^SC command to change the printer to the desired settings. 2. Change the host computer settings to match the new printer settings. Refer to the ZPL Programming Guide for more information about this command. 980612-001 Rev. C GX420t / GX430t User Guide 8/4/10 Getting Started 29 Connecting your Printer to a Computer EPL Y Command Use the serial port setup (Y) command to change the communications settings on the printer. 1. With the host computer set at the same communications settings as the printer, send the Y command to change the printer to the desired settings. Note: the Y command does not support setting the data flow control, use the Xon/Xoff setting. 2. Change the host computer settings to match the new printer settings. Refer to the EPL Page Mode Programming Guide for more information about this command. Resetting the Default Serial Port Parameters Do the following to reset the communications parameters on the printer to the factory defaults (serial communication settings are: 9600 baud, 8 bit word length, NO parity, 1 stop bit, and DTR/XON/XOFF data flow control). 1. Press and hold the feed button until the green status LED flashes once, waits a moment and flashes twice, and then waits again before flashing three times (release immediately). 2. While the status LED rapidly flashes amber and green, press the feed button. Serial communications between the printer and the host computer can be set by the ZPL ^SC command or the EPL Y command. Note • Early models of Zebra® printers running the EPL programming language had 9600 baud, NO parity, 8 data bits, 1 stop bit and a HARDWARE and SOFTWARE (merged) data control (essentially DTR/Xon/Xoff) as the default serial port settings. The Windows operating system flow control setting was Hardware for most applications. Tighten Serial Cable 8/4/10 GX420t / GX430t User Guide 980612-001 Rev.

C 36 Print Operations Determining Printer Configuration Determining Printer Configuration The G-Series printer uses a ZPL printer configuration status label to report the printer’s configuration status for both EPL and ZPL operations.The ZPL style label provides a more intuitive and functionally descriptive naming conventions than the EPL style printer status label. Operational status (darkness, speed, media type, etc.), installed printer options (network, interface settings, cutter, etc.) and printer description information (serial number, model name, firmware version, etc.) are all includes on the status label. See Printing a Test (Printer Configuration) Label on page 23 to print this label. See Appendix: ZPL Configuration on page 119 for detail on printer configuration and the ZPL commands that control the printer settings listed on the Printer Configuration Status Label. To get an EPL style printer configuration status label, send the printer the EPL U command. See the EPL programmer’s guide for more information on the various EPL U commands and interpreting the settings displayed on these labels. Localizing the Printer Status Configuration Label The printer configuration status label can be localized for up to 16 languages. Use the ZPL programming command ^KD to modify the displayed language for most status items on this label. See Printing a Test (Printer Configuration) Label on page 23 or Feed Button Modes on page 106 for information on accessing the printer configuration status label. Long Term Printer In-activity or Storage Overtime the printhead may stick to the platen (drive) roller. To prevent this, always store the printer with a piece of media (a label or paper) between the printhead and platen roller. Do not ship the printer with a roll of media installed or damage to the printer or media may result. Thermal Printing Caution • The printhead becomes hot while printing. To protect from damaging the printhead and risk of personal injury, avoid touching the printhead. Only use the cleaning pen to perform printhead maintenance.

C GX420t / GX430t User Guide 8/4/10 Print Operations 37 Modes of Printing Modes of Printing You can operate this printer in many different modes and media configurations: • Direct thermal printing (which uses heat sensitive media to print). • Thermal transfer printing (which uses ribbon to heat transfer print to the media). • Standard Tear-Off mode allows you to tear off each label (or batch print a strip of labels) after it is printed. • Label Dispense Mode: If an optional dispenser is installed, the backing material can be peeled away from the label as it is printed. After this label is removed, the next one is printed. • Media Cutting: If an optional media cutter is installed, the printer can cut the label liner between labels, receipt paper or tag stock depending upon the cutter option purchased. • Stand-alone: The printer can print without being connected to a computer using the printer’s auto running label form feature (programming based) or by using a data input device connected to the printer’s serial port. This mode accommodates data input devices, such as scanners, weigh scales, Zebra® KDU Plus™ or KDU (Keyboard Display Unit) with a KDU Adapter, etc. • Shared network printing: Printers configured with the Ethernet interface option include an internal print server with ZebraLink™ printer configuration web page and ZebraNet™ Bridge software for managing and monitoring status of Zebra® printers on a network. Print Media Types Important • Zebra strongly recommends the use of Zebra-brand supplies for continuous high-quality printing. A wide range of paper, polypropylene, polyester, and vinyl stock has been specifically engineered to enhance the printing capabilities of the printer and to prevent premature printhead wear. To purchase supplies, go to zebra.com/howtobuy. Your printer can use various types of media: • Standard media—Most standard (non-continuous) media uses an adhesive backing that sticks individual labels or a continuous length of labels to a liner. • Continuous roll media—Most continuous roll media is direct thermal media (similar to FAX paper) and is used for receipt or ticket style printing. • Tag stock—Tags are usually made from a heavy paper (up to 0.0075in./0.19mm thick). Tag stock does not have adhesive or a liner, and it is typically perforated between tags. For more information on basic media types, see Table 1. The printer typically uses roll media, but you can use fan-fold or other continuous media too. Use the correct media for the type of printing you require. You must use direct thermal media.When printing without a ribbon, you must use direct thermal media. When using ribbon, you must use thermal transfer media. 8/4/10 GX420t / GX430t User Guide 980612-001 Rev. C 38 Print Operations Print Media Types Table 1 • Types of Media Roll and Fanfold Media Media Type How It Looks Description

Non-Continuous Roll Media Non-Continuous Fanfold Media Continuous Roll Media Roll media is wound on a core that can be 0.5 to 1.5 in. (12.7 to 38.1 mm) in diameter. Labels have adhesive backing that sticks them to a liner, and they are separated by gaps, holes, notches, or black marks. Tags are separated by perforations. Individual labels are separated by one or more of the following methods: • Web media separates labels by gaps, holes, or notches. • Black mark media uses pre-printed black marks on the back side of the media to indicate label separations. • Perforated media has perforations that allow the labels or tags to be separated from each other easily. The media may also have black marks or other separations between labels or tags. Fan-Fold media is folded in a zigzag pattern. Fanfold media can have the same label separations as non-continuous roll media. The separations would fall on or near the folds. Roll media is wound on a core that can be 0.5 to 1.5 in. (12.7 to 38.1 mm) in diameter. Continuous roll media does not have gaps, holes, notches, or black marks to indicate label separations. This allows the image to be printed anywhere on the label. A cutter can be used to cut apart individual labels. With continuous media, use the transmissive (gap) sensor so the printer can detect when the media runs out.

980612-001 Rev. C GX420t / GX430t User Guide 8/4/10 Print Operations 39 Replacing Supplies Determining Thermal Media Types Thermal transfer media requires ribbon for printing while direct thermal media does not. To determine if ribbon must be used with a particular media, perform a media scratch test. To perform a media scratch test, complete these steps: 1. Scratch the print surface of the media with a finger nail or pen cap. Press firmly and quickly while dragging it across the media surface. Direct thermal media is chemically treated to print (expose) when heat is applied. This test method uses friction heat to expose the media. 2. Did a black mark appear on the media? If a black mark... Then the media is... Does not appear on the media Thermal transfer. A ribbon is required. Appears on the media Direct thermal. No ribbon is required. Replacing Supplies If labels or ribbon run out while printing, leave the printer power on while reloading (data loss results if you turn off the printer). After you load a new label or ribbon roll, press the Feed button to restart. Always use high quality, approved labels, tags and ribbons. If adhesive backed labels are used that don’t lay flat on the backing liner, the exposed edges may stick to the label guides and rollers inside the printer, causing the label to peel off from the liner and jam the printer. Permanent damage to the printhead may result if a non-approved ribbon is used as it may be wound incorrectly for the printer or contain chemicals corrosive to the printhead. Adding a New Transfer Ribbon If ribbon runs out in the middle of a print job, the indicator lights red and the printer waits for you to add a fresh roll. 1. Keep the power on as you change ribbon. 2. Open the top cover, then cut the used ribbon so you can remove the cores. 3. Load a new ribbon roll and empty ribbon core. If necessary, review the Ribbon Loading steps. Note: Do Not Use ribbon cores with damaged notch. The notches should have square corners. 4. Close the top cover. 5. Press the Feed button to restart printing. 8/4/10 GX420t / GX430t User Guide 980612-001 Rev. C 40 Print Operations Adjusting the Print Width Replacing a Partially Used Transfer Ribbon To remove used transfer ribbon, perform the following steps. 1. Cut the ribbon from the take-up roll. 2. Remove the take-up roll and discard used ribbon. 3. Remove the supply roll and tape the end of any fresh ribbon to prevent it from unwrapping. When reinstalling a partially used supply roll, tape the cut end onto the empty take-up roll. Adjusting the Print Width Print width must be set when: • You are using the printer for the first time. • There is a change in media width. Print width may be set by: • The Windows printer driver or application software such as ZebraDesigner™. • The five-flash sequence in Feed Button Modes on page 106. • Controlling printer operations with ZPL programming; refer to the Print Width (^PW) command (consult your ZPL Programming Guide). • Controlling printer operations with EPL Page Mode programming, refer to the Set Label Width (q) command (consult your EPL Programmer’s Guide). Adjusting the Print Quality Print quality is influenced by the heat (density) setting of the printhead, the print speed, and the media in use. Experiment with these settings to find the optimal mix for your application. Print quality can be set with the Zebra Setup Utility’s ‘Configure Print Quality’ routine. Note • Media manufactures may have specific recommendations for speed settings for your printer and the media. Some media types have lower maximum speeds than your printer’s maximum speed. The relative darkness (or density) setting can be controlled by: • The six-flash sequence in Feed Button Modes on page 106. This will overwrite any ZPL and EPL programmed darkness/density settings. • The Set Darkness (~SD) ZPL command (consult your ZPL Programming Guide). • The Density (D) EPL command (consult your EPL Programmer’s Guide). If you find that the print speed needs to be adjusted, use: • The Windows printer driver or application software such as ZebraDesigner™. • The Print Rate (^PR) command (consult your ZPL Programming Guide). • The Speed Select (S) command (consult your EPL Programmer’s Guide). 980612-001 Rev. C GX420t / GX430t User Guide 8/4/10 Print Operations 41 Media Sensing Media Sensing The G-Series printer has automatic media sensing capability. The printer is designed to continuously check and adjust media length sensing for minor variations. Once the printer is printing or feeding media, the printer continually checks and adjusts the media sensing to accommodate for minor changes in media parameters from label to label on a roll and from roll to roll of media. The printer will automatically initiate a media length calibration if the expected media length or the label to label gap distance has exceeded the acceptable variation range when starting a print job or feeding media. The automatic media sensing in the G-Series printers works the same for printer operations that use EPL and ZPL label formats and programming. If the printer does not detect labels or black marks (or notches with blackline sensing) after feeding the media the default maximum label length distance of 39 inches (1 meter), then the printer will switch to continuous (receipt) media mode. The printer will keep these settings until changed by software, programming or a manual calibration with different media. Optionally, the printer can be set to do a short media calibration after printer power up or when closing the printer with power on. The printer will then feed several labels while calibrating. The printer’s media settings can be verified by printing a Printer Configuration label. See the Printing a Test (Printer Configuration) Label on page 23 for more details. The maximum distance that the automatic media type detection and sensing will check can be reduced by using the ZPL Maximum Label Length command (^ML). It is recommended that this distance be set to no less than two times the longest label being printed. If the largest label being printed was a 4 by 6 inch label, then the maximum label (media) length detection distance can be reduced from the default distance of 39 inches down to 12 inches. If the printer has difficulty automatically detecting the media type and auto-calibrating, see Manual Calibration on page 102 to perform an extensive calibration. It includes a printed graph of sensor operation for your media. This method disables the printer’s automatic media sensing capability until the printer’s default parameters are reset to the factory defaults with the four flash Feed button mode. See the Feed Button Modes on page 106 for more details. The automatic media calibration can be modified, turned on or turned off to meet your needs. Sometimes print job conditions require that the printer use all the media on a roll. The two automatic media conditions, power up with media loaded and closing the printer with power on, can be controlled individually with the ZPL Media Feed command, ^MF. The feed action discussed in the ZPL programmers guide for the ^MF command is primarily for automatic media sensing and calibration. The automatic media calibration that controls the dynamic media (label to label) calibration is the ^XS command. If multiple media types of different lengths, material or detection methods (web/gap, black mark, notches or continuous) are used, you should not change these settings. The media calibration and detection process can also be refined to match the media type loaded into the printer. Use the ZPL Media Tracking command (^MN) to set the media type. Sometimes the printer can detect preprinted media as the gap between labels or the liner backing with print as a black marks. If the ^MN parameter for continuous media is set, then the print does not preform the automatic calibration. The ^MN command also includes an automatic calibration parameter (^MNA) to return the printer to its default setting to automatically detect all media types. 8/4/10 GX420t / GX430t User Guide 980612-001 Rev. C 42 Print Operations Ribbon Overview Ribbon Overview Ribbon is a thin film that is coated on one side with wax, resin, or wax resin, which is transferred to the media during the thermal transfer process. The media determines whether you need to use ribbon and how wide the ribbon must be. When ribbon is used, it must be as wide as or wider than the media being used. If the ribbon is narrower than the media, areas of the printhead are unprotected and subject to premature wear. When to Use Ribbon Thermal transfer media requires ribbon for printing while direct thermal media does not. Direct thermal media should never be used with ribbon. Bar codes and graphics can get distorted. To determine if ribbon must be used with a particular media, perform a media scratch test. Coated Side of Ribbon Ribbon can be wound with the coated side on the inside or outside. This printer can only use ribbon that is coated on the outside. If you are unsure which side of a particular roll of ribbon is coated, perform an adhesive test or a ribbon scratch test to determine which side is coated. Outside Inside To determine which side of a ribbon is coated, complete these steps: Ribbon Test with Adhesive If you have labels available, perform the adhesive test to determine which side of a ribbon is coated. This method works well for ribbon that is already installed. To perform an adhesive test, complete these steps: 1. Peel a label from its liner. 2. Press a corner of the sticky side of the label to the outer surface of the roll of ribbon. 3. Peel the label off of the ribbon. 980612-001 Rev.

After printing or feeding several labels: If the media does not track down the center (moves from side to side) or the sides of the media (liner, tag, paper, etc.) are frayed or damaged when exiting the printer, then the media guides may need further adjustment. If this does not correct the problem, then the media can be routed over the two roll holding pins on the media guide. An empty roll core of the same width as the stack of the fan-fold media can be placed between the roll holders to provide additional support for thin media. 8/4/10 GX420t / GX430t User Guide 980612-001 Rev. C 46 Print Operations Printing with Externally Mounted Roll Media Printing with Externally Mounted Roll Media The G-Series printer accommodates externally mounted roll media similar to the printer’s support of fan-fold media. The printer requires the media roll and stand combination to have a low initial inertia to pull the media off the roll. The G-Series™ motor has 30% more torque than the Zebra® 2800™ Series desktop printers to provide improved media handling and speed. Zebra at this time does not offer an external media option for the G-Series™ printer. Externally Mounted Roll Media Considerations: • The media ideally should enter the printer directly behind the printer through the fan-fold media slot in the rear of the printer. See Printing on Fan-Fold Media on page 44 for media loading. • Lower the print speed to decrease the chance of motor stalls. The roll typically has the highest inertia when trying to start the roll moving. Larger media roll diameters require the printer to have more torque applied to get the roll moving. • The media should move smoothly and freely. The media should not slip, skip, jerk, bind and then move, etc. when mounted on your media stand. • The printer should not touch the media roll. • The printer should not slip or lift up off the operating surface. 980612-001 Rev. C GX420t / GX430t User Guide 8/4/10 Print Operations 47 Fonts and Your Printer Fonts and Your Printer The G-Series™ printer supports your language and font requirements with a variety of internal fonts, on-board font scaling, international font sets and character code page support, Unicode support, and font download. The G-Series™ printer’s font capabilities are programming language dependent. The EPL™ programming language provides for basic bitmapped fonts and international code pages. The ZPL™ programming language provides advanced font mapping and scaling technology to support outline fonts (TrueType™ or OpenType™) and Unicode character mapping as well as basic bitmapped fonts and character code pages. ZPL and EPL programming guides describe and document the fonts, code pages, character access, listing fonts, and limitations for their respective printer programming languages. See the printer programming guides for information on Text, Fonts and Character support. The G-Series printer includes utilities and application software that support font download into the printer for both printer programming languages. Identifying Fonts in Your Printer Fonts and memory are shared by the programming languages in the printer. Fonts can be loaded in many memory areas in the G-Series printer. ZPL programming can recognize EPL and ZPL fonts. EPL programming can only recognize EPL fonts. See the respective programmer guides for more information on fonts and printer memory. ZPL Fonts: • To manage and download fonts for ZPL print operation, use the Zebra Setup utility or ZebraNet™ Bridge. • To display all of the fonts loaded in your G-Series printer, send the printer the ZPL command ^WD. See the ZPL Programmers Guide for details. • Bitmap fonts in the various printer memory areas are identified by the .FNT file extension in ZPL. • Scalable fonts are identified with the .TTF, .TTE or .OTF file extensions in ZPL. EPL does not support these fonts. EPL Fonts: • To download fonts for EPL print operations, use the Zebra Setup Utility or ZebraNet™ Bridge to send files to the printer. • To display Soft Fonts (ext.) available to EPL, send the printer the EPL command EI. • Optional Asian Fonts in G-Series printers are displayed as Soft Fonts, but are still accessible as documented in the A command in the EPL programmer’s guide. • All EPL fonts displayed are bitmap fonts. They do not include the .FNT file extension or the horizontal (H) or vertical (V) designators that are displayed with the ZPL command ^WD as described above in ZPL Fonts. • To remove non Asian EPL fonts with EPL programming, use the EK command. • To remove EPL Asian fonts from the printer, use the ZPL ^ID command. 8/4/10 GX420t / GX430t User Guide 980612-001 Rev. C 48 Print Operations Fonts and Your Printer Localizing the Printer with Code Pages The G-Series printer supports two sets of language, region and character sets for permanent fonts loaded into the printer for each printer programming language, ZPL and EPL. The printer supports localization with common international character map code pages. • For ZPL code page support, including Unicode, see the ^CI command in the ZPL programmer’s guide. • For EPL code page support, see the I command in the EPL programmer’s guide. Asian fonts and Other Large Font Sets Asian language pictographic fonts have large character sets with thousands of characters that support single language code page. In order to support the large Asian character sets, the industry adopted a double-byte (67840 maximum) character system instead of the single-byte characters (256 maximum) used by Latin based language characters to address large font sets. In order to address multiple languages with a single font set, Unicode was invented. A Unicode font supports one or more code points (relate these to code page character maps) and is accessed in a standard method that resolves character mapping conflicts. The ZPL programming language supports Unicode; EPL does not. Both of the printer’s programming languages support the large pictographic double-byte character Asian font sets. Asian language support requires additional memory support by the G-Series printer configured with the RTC and Full Flash Memory factory option. The number of fonts that can be downloaded is dependent upon the amount of available flash memory not already in use and the size of the font to be downloaded. Some large Unicode fonts are too large to be installed in the early model G-Series printers (12MB Full Flash Memory prior to July 24, 2009) with the RTC and Full Flash Memory factory option such as MS (Microsoft) Arial Unicode font (23MB) available from Microsoft or the Andale font (22MB) offered by Zebra. These large font sets typically support a large number of languages as well. Getting Asian Fonts Asian bitmap font sets are downloaded into the printer by the user or integrator. The ZPL fonts are purchased separately from the printer. EPL Asian Fonts are available for free to download from the Zebra Web site. • Simplified and Traditional Chinese (ZPL and EPL) • Japanese — JIS and Shift-JIS mappings (ZPL and EPL) • Korean (ZPL including Johab and EPL) • Thai (ZPL only) 980612-001 Rev. C GX420t / GX430t User Guide 8/4/10 Print Operations 49 Stand Alone Printing Stand Alone Printing Your printer can be configured to work without being attached to a computer. The printer has the ability to automatically run a single label form. One or more downloaded label forms can be accessed and run with a terminal or wedge device or a Zebra® KDU (keyboard display unit) to call a label form. These methods allow the developer to incorporate data input devices, such as scanners or weight scales, to the printer via the serial port. Label formats can be developed and stored in the printer to support labels that have: • No data entry required and print when the Feed button is pressed. • No data entry required and print when a label is removed from the printer’s optional label dispenser. • One or more data variables to be entered via the terminal or wedge device. The label will print after the last variable data field has been input. • One or more label formats that are called by scanning bar codes containing programming to run a label form. • Label forms designed to work as a process chain with each label including a bar code containing the programming to run the next label in the process sequence. Both printer programming languages support special label forms that will automatically run after a power cycle or reset. The ZPL looks for a file named AUTOEXEC.ZPL and EPL looks for a label form named AUTOFR. If both files are loaded in the G-Series printer, then only the AUTOEXEC.ZPL will run. The EPL AUTOFR form runs until it is disabled. Both files must be deleted from the printer followed by a reset or a power cycle to completely remove the files. Note • The G-Series EPL AUTOFR command can only be disabled with NULL character (00 hex or ASCII 0). The G-Series™ printer will ignore the other character that normally disables the AUTOFFR form operation in most other EPL printers, the XOFF character (13 hex or ASCII 19). The G-Series™ printer can source up to 750mA through the serial port’s 5 volt line; see Appendix A for more information on the printer’s serial port interface. 8/4/10 GX420t / GX430t User Guide 980612-001 Rev.

The G-Series™ printer’s web (gap) sensing in the standard (fixed position) or the moveable sensor’s default position are offset from the center of the printer to allow for gap sensing of labels that are side by side on a roll - see below. CLDefault Gap Sensing Position Web (Gap) sensing with the movable sensor can only function when the sensor’s alignment arrow points to any position on the alignment key. The sensor must be aligned with the labels (or other media) to sense the gap between the labels. The example above shows where the sensor is set if center aligned positioning is used. It will miss sensing labels with a 2-up label configuration and with the sensor in the ‘default’ position, it will be able to the detect labels and the gaps between them. Adjustment Range - Left to Right Center Aligned Default • Default — Zebra Models: G-Series™ fixed position sensors, LP/TLP 2842™, LP/TLP 2844™, LP/TLP 2042™ • Center Aligned — Zebra Model: LP/TLP 2742™ 980612-001 Rev.

C GX420t / GX430t User Guide 8/4/10 Printer Options 67 Bluetooth Option Bluetooth Option Bluetooth is an optional factory installed (internal wireless) device that can connect to other Bluetooth enabled devices and computers. The Bluetooth radio inside G-series printers complies with Bluetooth Specification 2.0 and supports the Serial Port Profile (SPP), a Windows virtual serial port. All print jobs sent to the printer on Windows PC’s will be done through the SPP, which is basically a Bluetooth emulation of an RS-232 serial communication. This printer option includes a LCD display to provide connection status and configuration information to assist with installation and connection to a Bluetooth enabled host system. Microsoft has supported most Bluetooth devices since the release of Windows XP Service Pack 2 (SP2). Prior to that, Bluetooth devices for earlier versions of Windows required drivers to be supplied with the device. Windows XP SP2 and above also include ‘Add a Printer’ wizard support for printers. The G-Series printer is accessed via a Bluetooth virtual serial port connection (SPP). The printer only needs Bluetooth 2.0 driver that supports SPP to be able to communicate with the Windows PC’s Bluetooth devices. In the Windows environment, the printer requires the ZebraDesigner™ driver to be installed on the computer to enable printing after Bluetooth communication has been established. Use the Zebra Setup Utility’s printer install wizards to help you configure your Bluetooth connection. Printer Network Configuration Status Label G-Series printers with the ZebraNet® Internal Bluetooth option on-board prints an additional printer configuration status label for information needed to establish and trouble shoot network printing.
