Hi,
There is an issue with the readonly values from the hp5590 backend and
the Scanjet 7650.
Listing the options specific to the hp5590, some report the scanner's
status:
--doc-in-adf
--color-led
--button-pressed
--counter-value
Trying to read these values with the command line gives an error:
$ scanimage --device-name hp5590 --color-led
Output format is not set, using pnm as a default.
scanimage: unrecognized option '--color-led'
They are, however, correctly reported when using -A:
$ scanimage -d hp5590 -A | grep color-led
Output format is not set, using pnm as a default.
--color-led color|black_white [color] [hardware]
<Pressing the button>
$ scanimage -d hp5590 -A | grep color-led
Output format is not set, using pnm as a default.
--color-led color|black_white [black_white] [hardware]
On Linux Mint 20.3:
$ scanimage --version
scanimage (sane-backends) 1.0.32; backend version 1.0.29
How do I access these readonly values using scanimage? I know I could
grep and cut for them, but that's not ideal.
Thanks,
