GC420d™ Thermal Printers

The Zebra® GC420d™ model is the best value in a desktop thermal printer. The GC420d™

printer provides direct thermal printing at speeds up to 4 ips (inches per second) at a 203 dpi

(dots per inch) print density. The GC420d™ supports both ZPL™ and EPL™ Zebra printer

programming languages and a wide variety of interface and feature options.

The GC420 printers feature:

• Automatic printer language detection and switching between ZPL and EPL

programming and label formats.

• OpenAccess™ design for simplified media loading.

• Color-coded operator controls and media guides.

• Zebra™ Global Printing Solution – supports Microsoft Windows keyboard encoding

(and ANSI), Unicode UTF-8 and UTF 16 (Unicode Transformation Formats), XML,

ASCII (7 and 8 bit used by legacy programs and systems), basic single and double

byte font encoding, Hexadecimal encoding, and custom character maps (DAT table

creation, font linking, and character remapping).

• Improved printer performance: faster print speeds and a 32-bit processor.

• A complete suite of free software applications and drivers to configure printer

settings, design and print labels and receipts, get printer status, import graphics and

fonts, send programming commands, update firmware, and download files. Clone

printer settings and send graphics, files, fonts, and firmware (updates) to one or more

Zebra® Ethernet and locally connected printers with ZebraNet™ Bridge.

• Maintenance reporting enabled and customizable by the user.

• The GC420 direct thermal printer models also include support for Line Mode printing

to support EPL1 legacy programming based printing applications.

The GC420 printers offer these basic printer options:

Loading Roll Media

5/23/2012 GC420d™ User Guide P1052685-001

Loading Roll Media

When you load media, you must place the roll onto the media hangers.

You must use the correct media for the type of printing you require.

Preparing Media

Whether your roll media is inside or outside wound, you load it into the printer the same way.

• Remove the outside length of media. During shipment, handling, or storage, the roll may

become dirty or dusty. Removing the outside length of media avoids dragging adhesive or

dirty media between the printhead and platen.

Pre-install Windows® Printer Drivers

P1052685-001 GC420d™ User Guide 5/23/2012

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 (www.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 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.

Connecting your Printer to a Computer

P1052685-001 GC420d™ User Guide 5/23/2012

Connecting your Printer to a Computer

The printer support a variety of interface options and configurations. These include: Universal

Serial Bus (USB) interface, RS232 Serial and Parallel (IEEE 1284.4).

• USB, Serial and Parallel

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.

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.

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.

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.

Connecting your Printer to a Computer

5/23/2012 GC420d™ User Guide P1052685-001

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

Connecting your Printer to a Computer

P1052685-001 GC420d™ User Guide 5/23/2012

Serial Communications

The GK888 has a DCE serial communication port for hardware compatibility with legacy 888

printers. 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. The cable

is a Null-Modem (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. This combined hardware

(DTR) and software (Xon/Xoff) mode may need to change depending upon use with non-

Zebra application software or 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.

Connecting your Printer to a Computer

5/23/2012 GC420d™ User Guide P1052685-001

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 8 NO baud, bit word length, 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.

Serial Cable

Connecting your Printer to a Computer

P1052685-001 GC420d™ User Guide 5/23/2012

Parallel Port

The required cable must have a 25 pin “D” type (DB-25P) male connector (host) on one end

and a Centronics (printer) on the other end (IEEE 1284 A-B parallel interface specification).

Parallel Cable

After Your Printer is Connected

5/23/2012 GC420d™ User Guide P1052685-001

After Your Printer is Connected

Now that you have basic communication to your printer, you may want to test printer

communications and then install other printer related applications, drivers or utilities.

Testing Communications by Printing

Verifying the print system’s operation is a relatively simple process. For Windows operating

systems, the Zebra Setup Utility or the Windows ‘Printers and Faxes’ Control Panel to access

and print a test label. For non-Windows operation systems, copying a basic ASCII text file

with a single command (~WC) to the printer will print a configuration status label.

Test Printing with Zebra Setup Utility:

1. Open the Zebra Setup Utility.

2. Click on the newly installed printer’s icon to select the printer and activate the printer

configuration buttons below it in the window.

3. Click the ‘Open Printer Tools’ button.

4. In the ‘Print’ tab window, click on the ‘Print configuration label’ line and click on the

‘Send’ button. The printer should print a configuration status label.

Test Printing with Windows ‘Printer and Faxes’ menu:

1. Click on the Windows ‘Start’ menu button, to access the ‘Printers and Faxes’ menu or

‘Control Panel’ to access the ‘Printers and Faxes’ menu. Open the menu.

2. Select the newly installed printer’s icon to select the printer and right-click the mouse to

access the printer ‘Properties’ menu.

3. From the printer’s ‘General’ tab window, click on the ‘Print Test Page’ button. The printer

should print a Windows test print page.

Test Print with a Copied ZPL Command File for Non-Windows Operating Systems:

1. Create a text file with the following ASCII three characters: ~WC

2. Save the file as: TEST.ZPL (an arbitrary file name and extension name).

3. Copy the file to the printer. For DOS, a file sent to a printer connected to the system’s

parallel port would be as simple as:

COPY TEST.ZPL LPT1

Other interface connection types and operating systems will have different command

strings. See your operating system documentation for detailed instructions to copy to the

appropriate printer interface for this test.

Determining Printer Configuration

P1052685-001 GC420d™ User Guide 5/23/2012

Determining Printer Configuration

The 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 15 to print this label. See Appendix: ZPL Configuration

on page 81 for details 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.

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.

Caution • The discharge of electrostatic energy that accumulates on the surface of the

human body or other surfaces can damage or destroy the printhead or electronic

components used in this device. You must observe static-safe procedures when working

with the printhead or the electronic components under the top cover.

Modes of Printing

5/23/2012 GC420d™ User Guide P1052685-001

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).

• 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.

• 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 Zebra® KDU (Keyboard Display

Unit), etc.

Print Media Types

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.

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 http://www.zebra.com/howtobuy.

Table 1 • Types of Media Roll and Fanfold Media

Media Type How It Looks Description

Non-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.

Non-Continuous

Fanfold Media

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.

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. 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.

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?

Replacing Supplies

If labels run out while printing, leave the printer power on while reloading (data loss results if

you turn off the printer). After you re-load media, press the Feed button to restart.

Always use high quality, approved labels and tags. 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.

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 70.

• 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).

Printing on Fan-Fold Media

P1052685-001 GC420d™ User Guide 5/23/2012

Printing on Fan-Fold Media

Printing on fan-fold media requires you to adjust the media roll holders’ stop position.

1. Open the top cover.

2. With a sample of your media, adjust the media roll holders to the width of the media. The

hangers should just touch, but not restrict, the edges of the media.Tighten the screw using

a small Phillips driver #1.

3. With a sample of your media, adjust the guides to the width of the media.The guides

should just touch, but not restrict, the edges of the media.

4. Run the media between the media guide and roll holders.

5. Close the top cover.

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 or roll holders may need further adjustment.

Fonts and Your Printer

5/23/2012 GC420d™ User Guide P1052685-001

Fonts and Your Printer

The GC420 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 GC420 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 GC420 printer includes utilities and application software that support font download into

the printer for both printer programming languages.

Localizing the Printer with Code Pages

The GC420 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.
