A "printer not responding" error can be caused by driver issues 1-877-331-5006, connectivity problems, or software conflicts. First, restart both your printer and computer. Check if the printer is set as default in Control Panel > Devices and Printers. Update or reinstall the printer drivers from Device Manager > Printers > Update Driver. If the printer is wireless, ensure it’s connected to the correct Wi-Fi network. Run the Windows Printer Troubleshooter by going to Settings > Devices > Printers & Scanners > Run Troubleshooter. If all else fails, reset the printer and try reconnecting it to your computer.
