Hi, I am having a printing issue. I have 1 desktop PC, 1 pc laptop and 1 apple laptop. I also have a HP LaserJet 4200/4300 series that is hooked up to the desktop pc via series port as well it is also joined to my Links wireless/wired router with a network cable. All my computers see the printer but will not print to it. Anybody have any ideas or know of a site that has a step by step on what I need to do. I very much need this fixed so any help would be great
