W2K12 enable 32-bit driver in print management

Trying to build print server using PS only. Added HP UPD. Had to use PNPUtil to add x64 driver, but that worked. Then added x86 the same way. PNPUtil part worked, but not add-printerdriver. When I open print management GUI, expand local server, drivers, I can check a box to add 32-bit. Can I do that in PS? I have found the -printerenvironment setting, but can’t seem to change it to “Windows NT x86”. Is it possible to do this? Thanks.

I’m running into the exact same issue. Wondering if anyone knows the trick to getting the x86 driver installed with Add-PrinterDriver?
