Public bug reported:
under Ubuntu 12.04 i could scan perfectly via the network from my HP
Photosmart Premium MFP (HP C309A), using gscan2pdf as frontend.
during Quantal beta and now on Quantal release, i cannot access the
network-connected scanner anymore: when opening the scan dialog in
gscan2pdf, the error message displayed is "Error opening device: End of
file reached".
on closer inspection, and having tried all the different backends
available in gscan2pdf, this seems related to the package libsane-hpaio:
if i downgrade this single package to libsane-
hpaio_3.12.2-1ubuntu3.1_amd64 from Precise i can scan ok (only side
effect is that gscan2pdf hangs on exit and needs to be killed with
signal SIGKILL).
in syslog, these are the lines that appear when using the newer libsane-
hpaio from Quantal when a frontend application tries to access the
scanner:
perl: io/hpmud/pp.c 627: unable to read device-id ret=-1
perl: io/hpmud/hpmud.c 611: invalid channel_open state
perl: failed to open scan channel: scan/sane/hpaio.c 659
perl: sane_hpaio_cancel: already cancelled!
perl: io/hpmud/hpmud.c 611: invalid channel_open state
perl: failed to open scan channel: scan/sane/hpaio.c 659
perl: sane_hpaio_cancel: already cancelled!
perl: io/hpmud/pp.c 627: unable to read device-id ret=-1
hp-check completes without errors nor warnings and correctly finds the
network-connected scanner:
