PC Won't Recognize Printer

I have a Dell Dimension 4600 with Win XP Home and a Canon Multipass 750 (Printer, Copier, Fax, Scanner.) The Dell died recently and was brought back by a service tech. The mother board was replaced according to the tech. (Dell phone support said something else was replaced...???)
Anyway everything is running well except, except the printer and the PC will not communicate. I cannot print nor scan nor fax from the PC. I called Canon and they offered little help. When the Service Tech left he did not plug the USB cables back in for the Canon, Cable Modem, Web came or Battery Back up.
I have tried deleting the printer by going to ControlPanel>PrinterFaxes to see if the PC would recognize new hardwire (The Canon uses USB). I have uninstalled and reinstalled the Canon drivers and I have tried different USB ports. Nothing helps. The Canon worked fine before the Dell hardware problem and it still will stand alone fax and copy.
Any ideas?
Thanks, Mike.

 

I'm going to guess the USB drivers weren't installed when they put the new motherboard in!!! Which i'm thinking is what Halo is headed towards!!

If it is the same model of motherboard...then the drivers should be on the dell disk that came with the system!!

*Didn't mean to step on your toes here, Halo...I just seen you weren't online at the time, and thought I would help incase he came back before you did!!!!*

I make no sense of your reply. The drivers are on the hard disk. It was not replaced. The drivers were there before. I uninstalled and reinstalled them in an attempt to solve the problem. Thanks, Mike.

 

Have you attempted what Halo said!!??
