Cause or Overview:
 | IMPORTANT! Ensure the settings in the printer driver and the label software are identical.
Verify that any printer configurations on your host application or driver are set to match those you have set on the printer. |
For example, the printer works fine when it prints self-test labels, configuration labels, etc.
You then send a print request from your PC or host, the printer settings change, or the printer goes into an error condition.
- Software always overrides the printer settings. A driver or label software can send ZPL commands overriding existing printer configurations. The printer may receive a configuration command with the label format that changes your initial setting. It could be telling the printer to print darker, to change label modes, or, if it is using ribbon, not to use it.
- If the printer is working fine with the initial setup and prints test labels correctly, you then send a label and experience an error; misconfigured driver or label software may be the cause of the issue.
- Always check if the settings in the driver and your printing software are the same. Refer to articles:
- Ensure that you have installed the latest firmware version and the printer driver.
- The ZDesigner driver and firmware files can be downloaded from the support page of your particular printer. Please, select the printer from the list.
 | NOTE Xi4, ZM-Series, 105SLPlus, and ZE500 (Vxx.17.16Z and later firmware) printers support selectively ignoring inbound ZPL and Set/Get/Do commands to avoid accidental misconfiguration. |
- If you can view the commands sent to the printer, look for those that impact the printer settings, such as ^Mx commands. These commands are typically in the first few lines of the format. You must eliminate them or verify the settings on the host application or driver to match the printer configurations.
