Can’t print multiple copies

My HP PSC 2510 printer will only print 1 page at a time even when I request 10 copies! The printer is not actually the problem; evidently I have changed something inadvertently in my laptop because I can copy the file to a thumb-drive, plug it in to another laptop on the same network and the printer will print multiple copies with no problem. I did load a game; could this affect the printer settings?
