How to Fix Printer “Port in Use” Error on Windows 10

Printers connect over a USB port. They require special drivers to work i.e., the USB drivers on your system alone won’t do the job. Sending a print job to a printer is tricky and often you’ll find that they stall or when a print job completes, the printer is unable to receive another print job.

Make sure you check the printer for paper jams and that it appears online. If it appears offline, try these fixes.

A printer can cause all sorts of problems. This can happen even if it was working just fine moments before. The older the printer is, the more likely it is to not work with Windows 10 that’s running on newer hardware. If the issue persists, check if the printer is still compatible with the latest Windows 10 builds. If it isn’t, you will either have to go back to a compatible Windows 10 build or buy a new printer.
