Printer not printing

At the printer - Is it switched on, with no error on its screen? Check for paper jams, empty trays and low toner. - Turn it off and on again.

On your computer - Make sure you've chosen the right printer in the print window. - Open the print queue (Windows: Settings → Bluetooth & devices → Printers & scanners → choose the printer → Open print queue). Cancel any stuck jobs, then print again. - Restart your computer.

If nobody can print to it, tell us the printer's name or location, and any message on its display.
