Could be a buggy driver.  Which printer model is it?

There is no driver currently assigned to printer.

Dunno.  Need more information.

The "2" and "3" subdircetoris represent driver versions. 
Ones remaining
in W32X86 did not get uploaded correctly.

Is padmin able to add printers via lpadmin?  Is padmin a member of the
ntadmin group?

What I meant was that some printer driver can be uploaded better
than others.  It is a really complex problem.  Can you upload
this same driver to an NT4/2k server?

What I'm fairly sure ishappening is that the SetPrinter RPC is
failing to assign the driver to the printer.
