Installation automation

I'm not fully sure if this is the right group or a group with
installation in it. I have unidrv based printer and I have an .msi file
for installation which seems to work.

Howerver it does the following on installation. It copies the files in
the DriverStore and from there I can get the files for the full install
while running the add printer wizard.

I know would like to have it install the printe without the need to
start the 'add printer wizard'. I have not idea
1) if one has to write some extra installer for tha task
2) wheter one can add something in the .msi file to force this installation


Unfortunatly I did not found anything about this area in neither a
white-paper nor the WinDDK nor the Platform SDK. I'm sure it must be
documented somewhere but I seem not to be able to find it.

so any hint or suggestion would be very welcome.
