Printer cartridge moves but does not print (by 2 users)

Just check that there is no paper trapped in the printer, you can normally get access at the back, other than that sounds like its worth uninstalling your printer driver and re-installing it, as sometimes the carrier grinds as if the paper settings or drivers are incorrect.

Make sure it's the drivers you got with the printer and not the generic windows drivers that sometimes take over when updating windows automatically.

Maybe your printer has finally give up and the circuitry is faulty.

Hope this helps
