Thanks for all the replies. I got a hold of the Win7 Professional Install disks and wiped the machine out and started all over again. Everything went smoothly this time and I had no problems in printing. I tried just about everything before deciding to take the "start over" route. The only thing I was never able to conclude was whether the HP LaserJet drivers were the culprits.
If anyone else runs into this I would just recommend to reinstall Win 7 Professional. It would have been the shortest and best solution.

Thanks Again for all the support.
