Windows XP SP2
Printer: Lexmark T640

This is a computer and a printer for a police department. The previous settings allowed the printer to print as both a network printer and straight from the computer via USB connection. The GREAT Tech guy updated or replaced the previous network server. Now when you hit print, it shows a split second box stating that whatever DOCUMENT is printing, then the box goes away and nothing prints. I cant even tell that the computer is actually communicating with the printer. I attempted installing the computer a second time using only USB, and then I hit print and get an error saying that the document was unable to print, and holds as error printing in the printers cache que. Printing with the original settings does not even load anything into the printers cache, it simply does nothing, not even an error message. I"ve attempted rebooting both, and went through the trobleshooter supplied by both Microsoft and the online Lexmark troubleshooter. Ive attemepted such possibilities as a firewall prohibiting the connection, printing from diferent programs such as notebook or word, and even tried uninstall, reinstall; and stopping and restarting the spooler. Nothing seems to help. I'm pretty sure that the new network has done something since it WORKED prior to updating the network, however I can't see how any network would interfere with a hardwired printer. And guess what, so far Tech guy is clueless. Has ANYONE run into a similar problem, any thoughts. Thanks in advance.OMG, I feel really smart but I really got to give props to the Tech Guy. Finally I see that the USB CORD is plugged into the wrong computer out of three that are next to the monitor. Thanks anyways guys.
