Any ideas? It just took my printer one hour and 10 minutes to print an 83-page PDF (text and images, but text-heavy) on my HP OfficeJet Pro 8620 from a MacBook Pro OS X 10.10.3. Very frustrating, to say the least.
I have already reset the print system, repaired disk permissions and unplugged/replugged the printer (waited a few minutes before plugging back in).
Any ideas??
