You'll need specific printing software written for Windows x64. 32-bit
software for your printer will NOT work.
Now the bad news. Dell doesn't have any 64-bit drivers for the 922. It
does have drivers for the following AIOs.... 944, 946, 926 and 966. Not
knowing the 922, I have no idea how close it is to the 926, but you may wish
to try them:

They may work, but no one will guarantee it.
There are a few multifunctions by other manufacturers that also support x64,
Canon's MP830 and MP530, Epson's RX580 etc.
I'd first try the 926 drivers before anything else.... then it's up to you
whether you want to continue with Windows x64 and think about a new printer
or revert to 32-bit Windows and keep the existing printer.
