hpaio missing in dll.conf for network scanner
Last modified: 2012-04-23 14:04:03 EDT
Description of problem:
dll.conf missed hpaio name after installing libsane-hpaio which is needed for network scanner
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Use Printers inside System Setting on Gnome Shell
2. An networked HP all-in-one printer (Photosmart eStation in this example) should be detected and appropriate drivers assigned
hpaio is missing in dll.conf
hpaio library should be included in /etc/sane.d/dll.conf allowing functionality of scanner from a networked all-in-one printer
The libsane-hpaio package ships /etc/sane.d/dll.d/hpaio which should be sufficient to enable the hpaio backend driver. Before libsane looked in dll.d/ for files like this, external drivers like hpaio needed to manipulate dll.conf directly, but this is fortunately no longer necessary.
Do you have an issue with your scanner not being recognized?
Good to know. It turned out the printing system detection on Gnome-Shell did not pick the right driver for HP Photosmart eStation c510a (hplips) through the network hence the seemly lack of scanner presence.
I had to use system-config-printers application to get that network scanner functionality. In that case, gnome printing system should use hplip by default. You can close the bug if you like. Thanks for the hint.
