FS#651 - brightness/contrast, etc on the UP-D898 family

There's presumably a way to configure this stuff from the host side,  In a FILE output mode the Windows drivers don't allow these settings to be changed, so to make this happen I'll have to obtain sniffs.

copy count fixed.

I think the brightness/contrast is always set by the driver, but the front panel settings are passed back in the IEEE1284 info.

There doesn't appear to be any change in the IEEE1284 dump when sharpening & brightness settings were changed.  More experiments to be done, I guess.
