Comment 6 for bug 1821932

Hi brian_p,

Turning AirPrint off does not help. Screenshot of printer's settings is attached. The error messages are exactly the same as with AirPrint enabled.

Modification of models.dat eliminates "no attributes found" error, but scanimage -L shows another entry:
[alex@alex-ub Загрузки]$ scanimage -L
device `v4l:/dev/video0' is a Noname USB2.0 HD UVC WebCam: USB2.0 HD virtual device
device `hpaio:/net/HP_LaserJet_MFP_M28-M31?ip=192.168.0.227' is a Hewlett-Packard HP_LaserJet_MFP_M28-M31 all-in-one
device `hpaio:/net/laserjet_mfp_m28-m31?ip=192.168.0.227&queue=false' is a Hewlett-Packard laserjet_mfp_m28-m31 all-in-one

And scanning does not work with I/O Error.
