I have a print server running on a raspberry pi. I tried adding sane,
but had trouble:
I am using HPLIP v3.18.12 (a bit old, but I couldn't build from
source, maybe because of the ARM on rpi? Had to use the apt package
which comes with raspbian)
I am running sane-backend 1.0.27 (also not newest. Newest apt package
on Raspberry Pi OS)
And the newest version of Raspberry Pi OS (2021-05-07)
I know HPCUPS work, so HPLIP should be functioning.
In /etc/sane.d, I created 2 files:
hpaio.conf
hpljm1005.conf
In both those files, I put the following:
# HP LaserJet MFP M436dn
/dev/usb
usb 0x03f0 0xaa2a
The vendorId and deviceID I put here are exactly from my printer. I
was hoping that I could force either of these two drivers to run on
the printer. Below is the output of "sudo sane-find-scanner" for evidence:
found USB scanner (vendor=0x03f0 [Hewlett-Packard], product=0xaa2a [HP
LaserJet MFP M436]) at libusb:001:002
Still, I get no scanners recognized from "sudo scanimage -L"
We recently had another user reporting a very similar problem:
https://gitlab.com/sane-project/frontends/-/issues/23
Same deal really. hpaio backend loaded OK according to the dll diag and
the model should be supported by the version loaded.
We couldn't really figure it out and I ended up redirecting them to
HPLIP's resource here:
