Resolution / Answer
||NOTE The printer can be configured using any number of applications, utilities, or using a Zebra Printer Driver. If there are changes that are needed for the printer settings, determine your application's method used to alter these settings.
For example: If you need to increase or decrease the darkness setting, you will need to determine if this action is performed on your driver, or application, or both. Zebra provides utilities for printer setup (refer to Helpful Information below) but once you have established your application driver or software or program, you will need to determine the methods used for modification of the printer settings.
Print quality is a product of proper printer setup and the use of compatible media for the application. The four impacting factors to consider are:
Media and Ribbon (if used) capabilities
Not all media are the same when it comes to being compatible with your application or needs. Printing speed, the durability of the image or 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.
There are no printhead pressure adjustments on the G-Series Printer.
The printer is capable of printing at multiple print speeds. The speed selection takes the media or 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.
For example: To set the print speed using the ZebraDesigner Driver, follow these steps:
(Go to Printing Preferences > Options > Print Speed).
For more information, refer to the ZebraDesigner Driver Printer Configuration Printing Preferences vs Printing Defaults.
Print Darkness also referred to as (Density or Burn Temperature) is a user-adjustable setting. Avoid overheating the ribbon as it can melt if it is set too high. Try varying the darkness to produce the best print quality.
For example: To set the darkness using the ZebraDesigner Driver, follow these steps:
(Go to Printing Preferences > Options > Darkness). For more information, refer to the ZebraDesigner Driver Printer Configuration Printing Preferences vs Printing Defaults article.
||IMPORTANT! All printer settings can be impacted by commands from a mismatched 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 is 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 has a setup configuration that sends these as commands to the printer. Make sure all settings match the printer settings to avoid intermittent issues.
Problems and Resolutions
Utilities and Drivers
A printer self-test label can be used to determine if the given print quality issue is seen from the printer itself and to test any changes made on the printer as you are troubleshooting the issue.
Print a test label using the Feed Button method.
Refer to: Printing a Test (Printer Configuration) Label.
The printer operates at the selected speed in terms of inches/mm per second. That is because the print quality is affected by print speed, media, ribbon (if thermal transfer), and printer operating modes, it is important to run tests for your application to choose the optimal print speed setting. Slowing down the print speed can also help if the print is too light.
The darkness level can be set directly on the printer, through the button flash method. Refer to the User Guide: Feed Button Modes for more information
Methods used to alter your print speed and darkness varies based on your application:
The configuration label will let you view the present printer settings. Your printer supports two languages. (ZPL preferred) Use the method supported by the language your printer is using to see the printer configurations.
