Hello,

I'm developing a WIA Microdriver and I need a way to
restrict the page sizes that are available through the
WIA UI. The device I'm developing for only supports a
few page sizes and if I return "not supported" for the
other available page sizes, the current application
usually gives some kind of scan failed message. I had a
similar problem with Resolutions, but I discovered that a
registry key could be created in the DeviceData section
of the driver that would restrict the available
Resolutions. I have not been able to find a similar
registry key for page size though. Any help would be
appreciated.

Thanks,
Danny
