I have a Canon TS9120 which is a fairly new printer/scanner.
scangearmp2 is the only program that will work with the scanner.
Version 3.50 ScanGear MP
And it has no way to adjust the scan resolution.
I have even looked tried to find a Windows scanner program that would work under wine.
Is there a place to submit suggestions for a fix or addition to an upcoming version of Ubuntu_Mate?
