Oh no, that "Printer port in use" error is super frustrating when you just want to print something! It's like your computer and printer are having a little disagreement about who gets to talk on the phone line.
Usually, this message pops up because another program or process on your computer is currently trying to use the same communication channel (the "port") that your printer needs.
Sometimes, the easiest thing to try is just restarting your computer and your printer. It sounds simple, but it can often clear out whatever was hogging the port. Think of it like telling everyone to hang up so the printer can make its important call.
If that doesn't work, it could be that a print job got stuck in the queue. You can check this by searching for "Print Management" in the Start menu and opening it. Look for your printer in the list and see if there are any documents stuck in the "Jobs" section. If there are, try right-clicking on them and canceling them.
Another possibility is that the printer driver is having a moment. You could try reinstalling the printer driver. First, uninstall your printer by going to Settings > Bluetooth & devices > Printers & scanners, clicking on your printer, and then clicking "Remove device." After that, head to the printer manufacturer's website, download the latest driver for your Windows version, and install it.
