We have a Lexmark Optra E310 laser printer attached locally (LPT1) to a PC that's running Windows NT 4.0 w/ SP4. We run a DOS based banking app which we need to print from. All was well and working fine until today when it just stopped printing. Tried printing from a DOS window and that doesn't work either. I've re-installed drivers. Nothing. Printing from Windows and any other Windows app works fine. When you send a print job the light on the printer doesn't even blink, and it makes no noise or anything. Anyone know how to get this thing to print from DOS?!?
