ok, I have tried the AddPrinter after the AddPrinterDriver API call

I get error code 1797 "ERROR_UNKNOWN_PRINTER_DRIVER"

If I check in the registry under
HKLM\\SYSTEM\CurrentControlSet\Control\Print\Print ers the printer is not
added.

AddPrinterDriver API call does not return an error?!

So the problem does seem to be with AddPrinterDriver - no printer driver
added, but no error logged.

If I manually add the printer - it appears in the registry path as above. If
I then run my install code I get error 1802 "ERROR_PRINTER_ALREADY_EXISTS"
which is what you would expect - and still points to a problem with the
AddPrinterDriver call.

Any other suggestions?

Regards
Colin
