snapshot doesn't have that version. This makes testing with what you
used previouly impossible.

I am going to assume (contrary to my normal practice) that installing
3.17.10+repack0-1 doesn't work for you either. Please correct me if that
isn't the case.

Let's see if we can move this bug on with a stab in the dark. :)

Edit /usr/share/hplip/data/models/models.dat and alter

 [hp_laserjet_pro_mfp_m277dw]

to read

 [laserjet_pro_mfp_m277dw].

Does 'scanimage -L' give a positive outcome? And can you scan?

Cheers,

Brian.
