YESSS, thank you very much, TWAIN driver is not installed by default, but I could do it. And definition is OK now. Thanks again.
Hello, Naps2 (8.2.1.0) works almost perfectly on my W11 PC. I only have one problem : I have only one profile, with 500 PPP. In the main window, I also typed 500. Scanned image stays with 300. I tried with mac quality in the profile, no change. I don't understand what the problem is. BTW printer is a Brother MFC-J4340DW using WIA.
