[python-win32] Re: Adding Printers on Windows XP

[Roger Upole]

A null DEVMODE usually indicates a problem with the printer
driver.  Are you sure you have the correct driver installed on
the local machine ?  Also, what do you get back from GetPrinter
for DriverName ?
A couple of things you could try:
   Use win32print.DocumentProperties to retreive the printer's
     DEVMODE
   Create one yourself using pywintypes.DEVMODEType()
     and insert it into the pInfo dict
