I have an HP PSC 2355 printer/scanner/copier. I noticed a few days ago that when I tried to scan something in, the HP scanning program told me there was no printer hooked up. Umm, okay, I'm looking at the plug that is plugged into my USB port, but okay. Then, today, I try to print a PDF from Preview and no go. It starts like it's gonna print and then BANG, printing of jobs is stopped. Try printing from Safari; nope. Mail; nada. I try to print a test page from the HP PSC 2355 menu. That works. But I can't print from any apps. I could print yesterday just fine. I have changed no settings. WTF happened.
