20 Most Recent Zebra LP 2844 Thermal Printer Questions & Answers

possibly not a real LP2844 but an LP2543, a printer mass produced for and used by UPS. refurbishers change the label and sell as LP2844 because they are almost identical.
if it has an AC-AC adapter, it is an LP2543. LP2844 uses a AC-DC adapter, and all LP2844's have USB ports.

UPS VOLTEGE PROBLEM PLEASE INSTALL HIGH VOLTGE UPS

Hi,
I had the very same problem but I know it could be several different reasons. In my case it was a media calibration issue. To perform calibration switch the power OFF, then pres FEED button and hold it, Power ON still holding and after three red flashes release it. Calibration report will print out. At the end of that print you should get "PRESS FEED TO END". Do it and it should be ok. Let me know if that worked.

Sounds like you may have taken out more than the fuse. In case there is still life the next thing to try is a printer reset

1) Turn printer off.
2) Hold down feed button whilst turning printer on.
3) Let go of the feed button as soon as it starts to flash and then wait.
4) Printer will measure out 4 labels then print out a Hex dump ending with a not to "Push Feed to Exit"
5) Push feed

Follow the above instructions, if you mess around tapping the feed button (not following the above) you can change the printer between line mode and page mode. To swap that back is another storey.

This is due to windows which has attributed a new virtual usbport.
Go to the printer port and try another one (the last one for example)

you need to have thermal direct labels to print to a thermal printer. heat turns the paper black. check your labels to see if you have thermal direct or tuern darkness up if it is thermal direct paper

Lizardlick,
I found this information in the user manual:
Let the print head to cool for one minute, then use a new
cleaning pen to swab the print elements (the thin gray
line on the print head) from end to end. NOTE: You do
not have to turn off the printer to do this.
If print quality remains poor after cleaning, try the
Save-a-Print Head cleaning film to remove buildup
without damaging the print head. Call your authorized
reseller for more information.

Go into printer options and select "Fit To Page"
