Large PDF files (tried several 700+ page books) do not open properly. They show between 50-80 pages total. When I try to print 50 pages my HP 4100 errors out after about 10 pages. I have tried to open files in preview, Chrome, and Safari. I also removed extra memory from printer first and used second network card on the printer, deleted printer from sys pref, and installed again. ---- I was able to print OK from another computer.
