How to fix port in use error?
Today, printers are connected to printer ports, specifically the USB ports which makes our life easier. Printers along with USB scanners are at their best.
But it doesn’t run smoothly all the time. Even the printers experience errors. Most of the errors in the printers are due to ports. The error occurred during port configuration taking place if the installed printer driver is corrupted or outdated or if the printer port is in use.
Another type of error is displayed as “ printer port in use, please wait!”. It is displayed when the printer is not ready to accept the next print command from the computer.
There are so many other errors that also occur in printers like Jamming of the printer, low-quality text, and images, high costs of printing, slow printing, and low ink levels. But the major error or problem that occurs in the printer is the port in use error. Let’s know a bit more about it.
When a printer receives commands from the computer, sometimes, the queue job of printing documents breaks. It is due to errors that occur during printing.
Most of the time, the common error faced by almost every printer is the port-in-use error. When this error occurs, the printer is not ready to receive another print request. This error usually occurs when you are using multiple applications or forget to stop the previously done process.
Sending a print job to a printer is a difficult task and when the printer completes a print job, it may not receive another print job. The error won’t go away even if you try again or wait for a minute.
