Printer not printing after changing USB port on DA50S, DA55S, DA70S, and DA75S printers

Learn how to resolve a DA50S, DA55S, DA70S, or DA75S printer not printing after changing the USB port.
Products affected: DA50S, DA55S, DA70S, DA75S


The printer is not printing after moving it to a different USB port. 



Unplugging the printer USB cable and plugging it in to another USB port on the same computer can create a new print device in the Windows Printers folder with a different USB port number. Depending on the software configuration and default printer selection, this may cause the printer to not print.


Try one of the following to resolve the issue:
  • Connect the printer to the original USB port on the computer (the one to which it was originally connected).
  • Delete the old printer configuration in the Windows Printer Control Panel, then connect the printer to the new USB port.
