If your printer is not printing, start by checking the basics: ensure it is powered on, properly connected via USB or Wi-Fi, and has paper loaded without jams[1][4][5]. Next, clear the printer queue on your computer to remove any stuck print jobs and verify that “Pause Printing” or “Use Printer Offline” are not enabled[1][4]. Restart both the printer and your computer to resolve temporary glitches[1][2][4]. If that fails, try uninstalling and reinstalling the printer driver to fix corrupt or outdated drivers[2][3][4]. Also confirm the printer is set as the default device on your computer and connected to the same network if using wireless printing[4]. Finally, check the ink or toner levels and clean any clogged printheads if applicable[2][5].
