This happens quite often, although it used to be a more common problem. Your printer just keeps spitting out endless sheets of paper, usually with some sort of gibberish code on them. Pushing buttons on the printer won’t do anything, and there’s usually nothing that can be done on your computer.

The first step is to unplug the printer and leave it unplugged for about a minute. See if this clears the printer’s memory and stops the printing. If the endless printing job stays in the memory, then you will have to unplug the printer and shut down your computer. The problem is with the print spooler, which stores information about your jobs and sends them to the printer. If the job is stuck in there, you should be able to cancel and delete it after you have unplugged the printer and restarted. Try these steps before you do anything drastic like reinstalling the drivers. For some new inkjets, this can be a pretty big pain since the drivers are so large.
