GK888 Series Printer Setup Overview
The Zebra Printer can be used in a wide variety of applications and must be properly configured to function with your media. (Labels, Tags, etc.) and ribbon (if used). In addition you will be required to set the label size, print darkness and print speed to optimize printing. The printer is typically configured from your host device using a driver, utility/software, or sending the printer's command language (EPL or ZPL). In summary, in most instances you will need connect the printer to your host device to setup and configure the printer.
The GK888 Series printer also allows for a button flash sequence to configure darkness, print width, set defaults, and calibrate the labels. It should be noted that these configurations will be overwritten by any driver or application settings when you send your label request. Feed Button configurations Read More>>
Important: If you are using a USB connection to the printer, install the driver before connecting the USB cable to the printer.
Do you need the ZebraDesigner Driver?
The ZebraDesigner Driver is used when a Windows Application requires a driver to print to the printer. (The driver converts the Windows Application output to the printer's language.) If you are using a label design software from a non-Zebra vendor check with that vendor to see if they provide their own driver before installing and using the Zebra Designer Driver. In addition, if you are using an application that directly outputs the printer's command language (EPL/ZPL) then do not use a Zebra Printer Driver. For these applications either send the label files directly to the printer or use a Generic Text Driver.
Important: All printer settings can be impacted by commands from a mis-matched or misconfigured driver or software application. A printer that is functioning fine after setup but fails or indicates an error after label requests are received are most likely affected by the host side misconfiguration of the driver or printer software settings. The host device that generates the printer commands for printing typically have setup configuration that send these as commands to the printer. Make sure all settings match the printer settings to avoid intermittent issues.
Media Related Settings and Calibration
A note regarding printer setup and configuration
The GK888-Series printer can be configured by your driver, host application, or a utility. In these examples we will use the Zebra Designer Driver to configure the printer. (The configurations are sent when printing using the driver or printing the driver test page) If you are using a non-Zebra application/driver/label software determine the methods used to set these configurations and be aware the terminology for each setting in your environment may be different.
1. Understanding your media
The Zebra Printer supports the use of many types and shapes of label/tags and knowing your media detail is important for proper configuration.
Here are the details you should know for printer media setup and configuration. For our examples we are using the ZebraDesigner Driver to show the configuration selections for each topic discussed below. Note: When using the ZebraDesigner Driver the configurations are sent to the printer when you request to print a label. (i.e. printing the Windows Test page will send the printer configurations)
Media Related Configurations
>Media Type (Tracking Mode) - Selections - Continuous, Web Sensing (gap), and Mark Sensing (Black Mark). Default is Web Sensing
ZebraDesigner Driver (Printing Preferences - Advanced Setup - Tracking Mode) Read More>>
If you are using media with an inter-label gap or a center hole set the Tracking Mode for Web Sensing.
If you are using media with a black bar or mark set the Tracking Mode for Mark Sensing.

>Print Method (Media Type) - Selections - Thermal Transfer (Using Ribbon) or Direct Thermal (No Ribbon) – Default - Thermal Transfer
Note: Print Method does not apply if your printer is a GK888D Direct Thermal only. There are no ribbon spindles or settings.

>Print Mode - Selections- Tear off, Cutter, Peel (Dispense) – Default is Tear off
This is related to the label presentation after printing and limited to the options you have installed. The GK888 Series Printer supports Tear Off, Cutter, (Cutter Option Required) and Peel (Dispense Option Required) Read More>>

>Media Loading - The media must be properly loaded for the Print Mode you intend to use.
2. Understanding the Media Sensors
The printer comes with sensors for label tracking based on the Media Type used. There is a reflective and transmissive sensor positioned slightly off centered in the media path. The sensor you will use requires configuration of the Tracking Mode (Mark/Web/Continuous) setting to function with the media you are using. A hole or black mark must pass over the media sensor's position to function correctly.

See the GK888T Upper Web and Ribbon Sensor Read More>>
Note: The GK888D Lower Web/Mark and upper Web sensors are located slightly forward of the GK888T sensors but will look similar.
3. Calibrate the printer for the media.
The printer does not measure the label length unless the default Power Up or Head Close values are altered to either Length or Calibrate. There are two calibration methods to consider if the labels fail to calibrate properly.
- The 2 Flash sequence will find the label gap and measure the label.
Performing the Calibration Procedure (Two Flash sequence) Read More>>
- The 7 button flash will perform a deeper analysis of the gap or mark and will produce a media sensor profile.
Performing the Manual Calibration Procedure (Seven Flash sequence) Read More>>
This applies to the GK888t when using applications where the use of ribbon is required. This is referred to as Thermal Transfer printing where an inked ribbon is used to produce the image on the label.
Ribbon Basics This explains the ribbon types and typical darkness and speed selections Read More>>
Ribbon Loading - The ribbon must be on a core that has notches to assure the ribbon spindle hubs will move with the ribbon rotation. The printer looks at the rotation of the ribbon sensor wheel to determine if the ribbon is loaded and functioning correctly. If the wheel is not turning the printer will stop printing had the Feed Button will flash red. See the ribbon sensor Read More>>

Print quality is a product of proper printer setup and use of compatible media for the application. The four impacting factors to consider are:
1. The Media and Ribbon (if used) capabilities. Not all media is the same when it comes to being compatible with your application or needs. Printing speed , durability of the image/media, environment are just a few factors to consider when determining the printer setup for the application. Trying to compensate for poor media compatibility by using high printhead pressure and/or darkness settings can impact your printer’s printhead life.
2. Printhead Pressure
There are no printhead pressure adjustments on the G-Series printer. Assure the printhead properly latches and the platen is not worn as these are the impacting items when printhead pressure may be an issue.
3. Print Speed
The printer is capable of printing at multiple print speeds. The speed selection take the media/ribbon (if used) compatibilities into consideration since if high Darkness settings are required to achieve acceptable print then slower rates should be used. If your application requires the highest print speeds available be sure your media supplier has recommended the correct media for your application.

4. Print Darkness
Print Darkness (also may be referred to as Density or Burn Temperature) is a user adjustable setting. Avoid over heating the ribbon as it can melt if set too high. Vary the darkness to produce the best print quality. Setting the darkness using the ZebraDesigner Driver (Printing Preferences - Options - Darkness) Read More>>
USB - A Zebra compatible driver must be installed before connecting the printer.

Printing App or Program
Zebra printers are command interpretation engines using printer commands to to define the printed images. The printer must receive the commands in the supported printer language such as ZPL, EPL, CPCL. The printer will not respond if the label format received does not contain the required programming commands for label printing. Programming commands can be entered into a file and communicated to the printer, received as an output through a driver from an application, or created using one of many Zebra Label Software packages on the market.
