The problem of the bug is mentioned here: https://sourceforge.net/p/gscan2pdf/bugs/389/#04ec/a0ea And here: https://gitlab.com/utsushi/utsushi/-/issues/68#note_626389990 In my experience, scanimage --help dynamically adapts its output upon the given options before --help, i.e., the stated default values of options differ upon them. Please compare: $ scanimage --source='Automatic Document Feeder' --scan-area=A4 --help [.....] Options specific to device `epkowa:usb:002:003': [.....] Geometry: --scan-area Maximum|A4|A5 Landscape|A5 Portrait|B5|Legal|Letter|Executive|CD [A4] Select an area to scan based on well-known media sizes. -l 0..215.9mm [5.89999] Top-left x position of scan area. -t 0..355.6mm [0] Top-left y position of scan area. -x 0..210mm [210] Width of scan-area. -y 0..355.6mm [297] Height of scan-area. --quick-format Maximum|A4|A5 Landscape|A5 Portrait|B5|Legal|Letter|Executive|CD [A4] Select an area to scan based on well-known media sizes. (DEPRECATED) [.....] $ scanimage --scan-area=A4 --source='Automatic Document Feeder' --help [.....] Options specific to device `epkowa:usb:002:003': [.....] Geometry: --scan-area Maximum|A4|A5 Landscape|A5 Portrait|B5|Legal|Letter|Executive|CD [A4] Select an area to scan based on well-known media sizes. -l 0..215.9mm [0] Top-left x position of scan area. -t 0..355.6mm [0] Top-left y position of scan area. -x 0..215.9mm [215.9] Width of scan-area. -y 0..355.6mm [355.6] Height of scan-area. --quick-format Maximum|A4|A5 Landscape|A5 Portrait|B5|Legal|Letter|Executive|CD [A4] Select an area to scan based on well-known media sizes. (DEPRECATED) [.....] The latter still lists --scan-area and --quick-format as A4, instead Maximum. In the opinion of the developer of gscan2pdf this is a bug. I too think, he is right, as if frontends rely on this help defaults, the user gets presented the wrong values in the GUI. Thanks to review this problem, -Ulf
