If you try to print, and for whatever reason, a printing error develops, any subsequent attempts to print will be held in the print queue.
Look down in the "tray", the area where the time is shown at the bottom of the screen, and look for a printer icon (looks like a printer). You may have to click on a little arrow on the left side of that area to see other icons.
If the printer icon is there, then click on it. This will bring up a box on the screen. It will show any printing jobs in the queue, and the first one may be in error, or just showing printing. Go to "file" at the upper left corner of this box, click, scroll down, and delete all print jobs. Then close the box.
Try to print something simple, like a short email and see if it prints. If so, problem may be solved. If it doesn't print in a reasonable time, then check the print queue again. If it is there, then you may want to uninstall / reinstall the drivers for the printer.
My sister in law, who I love dearly, will call regularly to say her printer is not working (again), and when we swing by, she has items in the queue, the first of which is in error. She has had 8 or 9 on at least one occasion.
If the icon is not there, listen to the others.
