I keep getting the error message when trying to print "Error printing to Lpt1 due to an unknown system file. Please restart windows and try again" I have tried restarting and no change. I have formatted hard drive then installed and reinstalled print drivers. I am running Win98Se The printer is an HP Deskjet 610C I also have a HP Scanjet3300C. I have installed Office 2000 and JASC Paint Shop Pro 7.
