When you say the printer is networked,do you mean you are usinsg it shared from another pc,or is the printer on the pc you are using?,if its on another pc try printing from the pc the printer is installed on.
wee eddie not too sure how much Mb it is as im out of the office today. However the user said yesterday that since last Friday, printing has slowed up. Before Friday he said the printing of PDF gave him no trouble at all. He hasnt installed any new software and i have cleared his cookies/temp folder and checked his hard drive too.
If his printer is using the Windows Printing System rather than On-printer Memory/storage.
Then the transfer of large PDF files could take a while. I have looked at some of my stored PDF and they range in size from 320Kb to 5.8Mb. The number of pages does not seem to be exactly related to the size. The largest is a 56 page, graphics heavy, Catalogue.
