If you try to print on your Canon printer occasionally, an error message can appear. The printer is being used by another PC. Typically, this error appears if you attempt to use the print command while the printer is already printing.

You will have this problem on a local printer as well as a network printer the majority of the time.

It is challenging to determine the exact source of this error message, however, factors including a jammed print queue, a non-functioning print spooler service, or driver problems may be to blame. In these situations, you can use a few simple fixes to solve the problem.

The print queue is typically the cause of this problem, and clearing the print queue typically fixes it.

6. Configure WSD Timeout

When multiple devices send print requests over the network, the later requests are added to the print queue and remain there until the first print request is processed.

The WSD timeout specifies how long a device will continue to wait for a response from the printer before giving up. Your print job will not run and you will receive the error message Another computer is using the printer if the printer does not react within that time-out period.

So, raising the WSD timeout duration will assist prevent this error message if there are many devices on the network that need to print. Please be aware, though, that extending the WSD time-out may attract new problems, so it’s important to choose the right amount of time.

Let’s look at how to set the Canon MX922 printer’s WSD timeout duration.
