If the printer was shared by another user, the user may have stopped sharing it, or the user’s Mac may be offline. If you don’t manage the printer, ask the person who does for help.
Make sure you have the correct version of your printer’s software (also called its printer driver). If necessary, install the latest printing software that came with the printer or from the manufacturer’s website. If you’re using a printer that another user is sharing, make sure you’re both using the same version of the printer software.

If none of the previous solutions work, the printer’s queue may be corrupted. Try deleting it and setting up your printer again.
