Thanks Manfred, On a fresh test system, I first installed my printer with the old .gpd file. Success. - Uninstall - removed *PrintableOrigin: PAIR(400, 400) from one of the forms defined in my .gpd - tried installing printer again Failure! I repeated the procedure (had to remove driver files from server properties) but this time kept the PrintableOrigin value, and was able to install the printer again. What is the correct approach for me? AFAICT PrintableOrigin makes absolutely no sense for me! :( OTOH defining forms is probably not what I want in any case... I just want the default to be A4. (or do I? Is there a user's default that would otherwise be picked?) -- Rune >> On Thu, Nov 20, 2008 at 5:53 PM, Wilner, Manfred <mwilner@xxxxxxxxx> wrote: >>> When you uninstalled the driver did you also clean up the Forms that >>> belong to your driver?
