I have found many solutions where there is already a 64bit driver.
This case is different. This is for an HP 5000 plotter. There are no 64bit drivers. So I can't "add 32bit drivers to an existing printer that is using 64bit drivers".
I am trying to add this printer, or the driver, using Print Management. It does not matter if I try this on a 32bit client or, on the 64bit server. In both cases I get this error message:
"the selected driver must be installed remotely from an x86 computer using type 3 user mode drivers"
Is there ANY way to add a printer that only has 32bit drivers, on a 64bit server?
