Public bug reported:
version 0.9.32-1
I use gscan2pdf on two different locations, where there are two
different officejet scanners.
On one location, when I start gscan2pdf, and select File->Scan, it does
'Fetching list of devices', and it chooses the printer that is
inaccessible on that location, then it opens a window that says 'Opening
Device', followed by a window stating 'Error opening device: Error
during device I/O'. After pressing 'Close' on that window, only the main
window remains, and File-Scan (or ctrl-G) opens an empty and
functionless "Scan Document" window. It is not possible to switch to the
other officejet that is accessible, because it always automatically
selects the inaccessible one and errors as described.
As a workaround, starting with 'gscan2pdf --device=test' allows
selecting of 'Rescan for Devices' in the "Scan Document" window, after
which both officejets appear in the list, and the correct one can be
chosen and scanning works perfectly.
I'm not sure if the bug is that it tries to connect to an inaccessible
(networked) hplip scanner, or if the bug is that after the device I/O
error message the program becomes useless, but as of now, I have to use
the --device=test workaround to use this program.
