HP LaserJet MFP M227sdn need binary driver to scan

[Giovanni Biscuolo]

Hello,

I've a new HP LaserJet MFP M227sdn.

The supported devices page at https://developers.hp.com/hp-linux-imaging-and-printing/supported_devices/index clearly states that this model do not need a proprietary binary driver (Driver Plug-in column says No).

I use Debian GNU/Linux 10 and installed hplip-data (ver 3.18.12+dfsg0-2) but when I try to use simple-scan I get this error:

pr 22 08:23:20 roquette simple-scan[15119]: io/hpmud/model.c 532: no laserjet_mfp_m227-m231 attributes found in /usr/share/hplip/data/models/models.dat

apr 22 08:23:37 roquette simple-scan[15119]: common/utils.c 277: Invalid Library hanlder pLibHandler = NULL.

The error disappears after I installed hplip and used "sudo hp-plugin" to install the binary driver.

Please can you confirm I need the binary driver to scan with this printer model?
If this is the case, please can you fix the list https://developers.hp.com/hp-linux-imaging-and-printing/supported_devices/index?

Please what can I do to buy a binary driver free MFP printer?

Thanks. Giovanni

The hp_laserjet_mfp_m227-m231 entry in /usr/share/hplip/data/models/models.dat
confirms this is the case. scan-type is 5. This uses the non-free SOAP2 protocol.

If it is put on the network, it is highly likely your device will do scanning
without a non-free plugin. See https://github.com/alexpevzner/sane-airscan.
I use this SANE backend on Debian with great success. I am very interested in
how it works for you.

Brian.

OK thank you for the check. Please is there some documantation about
models.dat fields, for example that scan-type 5 means SOAP2 protocol?

\O/ It works!

I installed sane-airscan from the custom Debian repo found in that
Github page and it worked... immediatly!

It's even better than with libsane-hpaio since libsane-hpaio AFAIU does
not work with saned; I already had a working saned service for my
previous USB scanner and now the very same service works with this eSCL
driver. Fantastic!

Thank you very much for the information, you save my day! (and my
multifunction printer :-) )

Best regards. Giovanni.

Please look at the end of models.dat.

Oh found thanks (I was expecting it at the head of the file :-) )

Thanks again. Giovanni.
