I have just installed Windows XP SP/2 onto my PC & connected a HP LaserJet 2100 Printer. Now, I cant print from this Windows. I keep getting "This document failed to print" error message. I have changed, delete & re-installed printer drivers but that didn't work. Other printers work well i.e. Oki ML520 Dot Matrix printer & also, I can print from DOS prompt with all printers. Here I mean, proper DOS O/S. I have tried 5 different printer cables to no avail. Since the printer prints via LPT port, I'd to buy a PCI LPT card but that didn't help either. It just does the same thing. I have replaced the Cartridges but nothing happenes . Looks like some people have/had the same problem on the internet, but I cant get to where they got help from. Please help!!!
