Some troubleshooting tips:


If printer installs but when you send print job - nothing happens:

 Go to Control Panel - Devices & Printers - Right click on printer- choose Remove. Turn printer Off then On again. Wait until printer will  install again, go to Printer Preferences- Options-set label size- Tools- Run Calibration and  try to print delivery label again. Don't print Windows test print. If unsuccessful - repeat procedure until Windows install printer correctly or can try through Device Manager-Printers- Uninstall.


 If printer prints empty labels.

First off all make sure that labels are loaded facing up. 

Use labels supplied with printer. Some labels are designed for Thermal Transfer only- they work with ribbon only.

If printer is printing empty label after printing correct one- Run Calibration.
