Yup, exactly what I am describing.  Thanks for the pointer.  Gives me a
good starting point.

OS/2 uses a DosPrintQGetInfo call, and gets its info in a PRQINFO_3 struct,
like windows.  The driver file itself has to be in the PRINTDRV share on
the server.  So, like, NT/95, if the OS/2 driver has the same name (on
OS/2, the pszDriverName field of PRQINFO_3 is parsed as <driver file
name>.<device name>, where <device name> can be blank), the driver download
should work fine.  You just have to manually copy the files from the OS/2
driver into whatever directory you share as PRINTDRV.  Problem is, just
like NT/95, the driver often has a different name...  Oh well...

Also, driver upload doesn't work from OS/2->NT, so you have to just
manually copy the files.  The OS/2 client does the work searching in the
