This is actually the wrong forum but we will eliminate all the possibilties. Is this an error message on the printer itself or the computer when you try to print?
What is the make/model of the printer?
Tried getting the most recent drivers?
HP OfficeJet T45
Bought around 2001 or so but has been working fine as a printer/fax/copier
For home use.....scanner stopped working a few years ago.
I don't know how to get drivers
Error message is on printer itself
