Just out of the blue it stopped working. My ink levels are o.k, no paper is jammed. I select to print and in the print que it says printing but nothing ever prints. I try and go to the printing spool to stop it so the que gets deleted, but when I try and print again it's the same thing, it's in the que saying printing but nothing prints. I tried removing my printer as a device and installing again but it still does the same thing. Any suggestions? I'm running windows 7 64 bit and my Printer is the hp all in one F4180 series.
