I finally got my printer working, several hours later.  I thought about simply updating my previous post however I wanted to document the steps I took in the likely event that I'll need to do it again.

1. Download 64-bit driver package and extract. (Dell AIO 922 x64 download)
2. Plug in printer via USB.
   • When prompted, decline to install driver (their "Recommended" driver does not work).  You may be prompted twice, decline any "help" each time.
   • You also may get an error about devices not being installed properly, that's ok.   We're overriding what Vista wants for a driver and supplying our own, correct version.
3. Go to the Control Panel and select "Printers"
4. Right click somewhere in the window and click "Server Properties"
5. Go to the "Drivers" tab and click "Add..." to launch the "Add Printer Driver Wizard"
6. Follow the wizard, selecting the appropriate processor architecture if not already selected.
7. When presented with the "Printer Driver Selection" page (very Windows 98-esque) click "Have Disk..."
8. When prompted for the location, point to the the inf file for your particular install.  For my All-In-One installation the correct location was C:\dell\drivers\R151379\drivers\Win_XP2K.  Why is my Vista x64 driver stored under an XP/2000 folder?  Quite frankly, I don't know.
9. Allow the driver to install.
10. After the install, exit/ok your way back to the "printers" area.
11. Now select "Add Printer"
12. Select "Local Printer"
13. Select your USB port from the existing ports, which is a virtual port.
14. Repeat steps 7-9
15. When asked to replace or use the current driver, opt to use the current driver.  Remember we set it up manually back in step 8.
16. Name your printer
17. At this point, the Dell printer software took over and I had to agree to some EULA.  Click/Navigate your way through these selecting optional items such as Sharing and default printer along the way.

That's it!  Only 17 long, arduous steps.  There may have been other steps/processes that would've worked, however a number of obvious ones failed miserably, such as simply clicking "Add Printer" or running Dell's installation software.
