Dell AIO 926 won't print, clean Win7 Install, worked once

I am having trouble with a Dell 926 printer. I downloaded R150575, which is what the Dell site suggested for Win7 64-bit.

I just installed the OS today followed by all the windows update patches. I have installed very little other software. After downloading the Dell driver, I extracted the zip and installed the driver via device manager. Then the Dell printer install tool appeared and did it's thing. Printer prints successfully.

I typically like to install driver-only without additional proprietary software, so I removed everything (Dell software & drivers) and was back to square 1.

I tried to install again through device manager without allowing the Dell tool to install additional software. When I cancelled, the Dell tool removed the drivers also. At this point I understand that I cannot easily install the driver without the additional software.

So that's fine, I will just install everything again and just use the printer. But when I install everything again, the printer will not work. I get this dialog saying "Communication Not Available". The scanner works fine.

Bidirectional printing is enabled, and port is USB003. Previously it was USB002. Maybe it was USB001 the first time when it was working? Well when I select USB001 it doesn't help.

Don't know what else to do at this point. Looking for some expertise!

By the way, I have tried removing all of the USB controllers from device manager and rebooting to allow windows to restore all of this. Still nothing.
