Dell AIO 926 failing to print

Hello all,

I am having some problems with a new AIO 926 and was hoping someone could shed some light. We upgraded from a Lexmark 3300 series (hardware failure). A new usb cable was purchased along with the 926. I removed the old lexmark drivers, software, etc. rebooted and then followed the instructions for setting up the new printer.

I was able to print the test page when prompted during the setup process. But when I return to windows (notepad, word) nothing prints. The printer icon flashes briefly in the task bar and then disappears. None of the jobs are listed in the queue. When I try running a Print Test Page it immediately pops up that the Test Failed.

Oddly enough, the scan feature works (both through the AIO software and the printer scan-to menu).

System info:

Dell Dimension 2400 (I think?)

Windows XP SP2

McAfee AV

Dell A-I-O 926 w/ USB cable

What I've tried:

Disconnecting, removing all related software/drivers, reinstalling new drivers and firmware from Dell.com.

Checked that Exceptions were listed as needed in Windows Firewall.

Thanks for your time!
