Cant change capabilities whith a WIA-TWAIN driver

Open PNunes540 opened this issue 2 years ago • 5 comments

Using a Fujistu 5120C with old version "pure" TWAIN driver all works fine. But with a Windows 10 x64 latest version WIA-TWAIN driver the settings are not assumed by scanner. Example, if I change to 300 DPI it still returns 150 DPI images. The same for all other capabilities. Has anyone had a similar experience? It seems NTwain does not work with TWAIN drivers encapsulated in WIA driver DLLs.

Looks like same goes for all scanners: https://stackoverflow.com/questions/52521593/ntwain-icapsupportedsizes-is-not-supported I'm having the same trouble with EPSON WF7620.

Same issue here... Going to try and debug it tomorrow. It says I can set the capabilities, but it fails when I do. Trying to change the DPI from 100 to 300 for example.
