The Printer occasionally gets jammed. Every time a new device connects, the message Another Computer Is Using The Printer is shown. One of the best ways to fix a printer is to recycle its hard power. The printer needs to be unplugged for at least a minute and turned off for this to work. Connect the device to your computer or network when it has been restarted. Try printing a document right now. The printer is accessible and is no longer in a busy state thanks to power recycling.
