scanning with HP LaserJet Pro MFP m227fdw requires driver plug-in even though it should not

[Patrick Schleizer]

http://hplipopensource.com/hplip-web/models/laserjet/hp_laserjet_mfp_m227-m231.html says "Driver plug-in" "None" and the footnote [8] '("No" or "None") A driver plug-in is not required nor available.'

[Mantas Kriaučiūnas (mantas)]

I've installed hplip version 3.17.7 (with libsane-hpaio, hplip-data and other needed libraries) on Ubuntu 16.04 from ppa:alindt/xenial-backports (default hplip 3.16.3 version from Ubuntu 16.04 doesn't support LaserJet MFP M227) and scanning started to work only after installing hp-plugin:

1. added HP LaserJet MFP M227sdn network printer with command "hp-setup -i", tried hp-scan command after hp-setup but without success:
error: SANE: Error during device I/O (code=9) is displayed in terminal

2. installed HP plugin with command:
 hp-plugin -i

After installing hp-plugin command hp-scan works fine :)

This is a mistake on the website which as of now is still not fixed.
