Hi,
After recently reviewing our support for parallel support devices, it
seem that the current Ubuntu package generation uses the build
option --enable-parport-directio which disables libieee1284 library
support.
There are many advantages to using the library rather than hitting
port devices directly (permissions, stable platform, sane device
names) and my tests seem to indicate that it is pretty stable and
reliable: https://gitlab.com/sane-project/backends/-/issues/578
After asking around it seems that using this option was felt to lead
to a more stable experience but that was probably *many* years ago
and much has changed.
libieee1284 hasn't been updated in ages and it seems to have a stable
API. I will update the SANE PPA to switch this option off and will
test with other devices that I have.
I appreciate that this is a fairly low priority item. :D
Want to mention that sane-backends is packaged at Debian, so you may
want to submit a Debian bug to reach the package maintainer:
https://bugs.debian.org/cgi-bin/pkgreport.cgi?src=sane-backends
With that said, and since any change affects the Ubuntu users by
default, gathering input here too is probably wise.
