I am trying to get my all-in-one HP scanner working. I don't like mdns and avahi and all that kitchen sink. I prefer printing and scanning using the printer IP address. So, I just installed sane-bakends and hpaio packages.
I created the hpaio URI using hp-makeuri -s <printer IP address>, and tried to scan using simple-scan and xsane, but both fail with "unable to connect to scanner" error. My scanimage -L also does not show the scanner. To find out what's wrong with sane-backends and hpaio, I printed the sane debug log. sane-backends is correctly passing the scan request to hpaio, but hpaio is not able to locate the scanner. Here is the hpaio log: $ export SANE_DEBUG_HPAIO=128 $ simple-scan hpaio:/net/ENVY_4500_series?ip=192.168.0.211 [05:37:42.189674] [sanei_debug] Setting debug level of hpaio to 128. [05:37:42.194465] [hpaio] sane_hpaio_init(): scan/sane/hpaio.c 356 [05:37:42.194514] [hpaio] sane_hpaio_get_devices(local=0): scan/sane/hpaio.c 377 [05:37:42.203302] [hpaio] sane_hpaio_open(/net/ENVY_4500_series?ip=192.168.0.211): scan/sane/hpaio.c 395 scan_type=0 scansrc=2149 [05:37:46.106613] [hpaio] sane_hpaio_exit(): scan/sane/hpaio.c 371 Any pointers as to what I am missing?
