I recently purchased a Surface X without fully understanding the limited number of arm64 print drivers. In fact, I have not been able to locate any available printers with drivers that can work with arm64. I have seen some rather confusing recommendations from tech support on this forum--I want to ask, simply, is there a list of printers that are compatible with arm64?
I haven't found a list, but the closest thing would be to follow theseinstructions to manually add a printer and browse through the list of drivers on your Pro X, or search the windows update catalog using the link on that page. Not knowing what printer you have, I'd suggest if one isn't available to try either of the generic PostScript or PCL drivers and see if that works with your printer. I got a Konica Minolta machine at work to print from mine using the PS driver.
I do know there is a built-in class driver for Brother Laser printers that works well.
