I recently started having a problem with one of my HP Laserjet 4+ printers. One day it was printing fine and the next day all it would print was a string of characters across the top of the page. Not only that, it would keep going untill it had run out of paper, and it would never print the document, test page, or whatever I sent to it. I tried turning it off and then back on to see if that would clear it out, but that didn't work. Does anybody know what the problem might be? I realy hate to lose this printer, it has been such a good printer up untill now.
