Applicable To

Resolution / Answer
 |
End Of Service Life (EOSL) Zebra no longer provides services or support for LP2844 products. This knowledge article is for your reference only and is no longer proactively updated. |
UPS Printers are only designed to work with UPS shipping applications and 4x6 shipping labels. The UPS driver is required when using the UPS Printer. Normal ZebraDesigner Driver from the Zebra Website cannot be used on these specialty printers.
 |
CAUTION Do not load the standard Zebra Printer firmware or use the ZebraDesigner Printer Driver. Special UPS firmware and printer driver are the only ones compatible with the printer. |
Technical Support
Zebra Technical Support will only support the printer as a standalone device to assure the printer is calibrated and able to print a self-test label. For example, determine the printer is functioning and able to print a label.
UPS Supportwill support the UPS Driver installation, configuration, and set up to allow printing from the Worldship application.
The UPS Driver is available on the UPS Website.
You can contact UPS Technical Support at 888-553-1118 (United States).
Common Problems
Print Quality
If there are white lines on the print, clean the printhead.
- For LP2844, refer to the article Video: LP or TLP Series Printer Printhead Cleaning.
- For ZP450, refer to the PDF ZP450: Printhead Cleaning.
|
NOTE If the white lines still appear, the printhead may need to be replaced. Review service options. |
If the print is too light or too dark, verify that the printer darkness setting in the UPS Driver is properly set to optimize the printing's intensity.
Communication failure
Procedure:
- Assure that the USB cable is properly connected.
- Check the printer setup in Windows to assure that the correct driver is used.
- Make sure that there are no multiple instances of the driver installed.
- Contact UPS Technical Support for driver setup assistance if the problem persists.
Calibration
If the red light flashes, there is an issue with the paper out, perform calibration.
- For UPS LP2844, refer to the article Video: Calibrating the LP/TLP2824, LP/TLP2844, and TLP3842 Series Printers.
- For UPS ZP450, refer to the article ZP Series: Calibrating the Printer. After calibration, the printer should feed on one label each time the Feed Button is pressed.
No self-test
If the printer fails to perform a self-test on power-up, review service options.
No Power
- For LP2844, verify the power supply connected to the printer.
- For ZP450, make sure that the power connector at the rear of the printer is properly seated in the receptacle.
