Description:
After updating to the last hplip version my printer isn't found, running hp-doctor it says its not supported despite being listed in models.dat
Reverting to 3.19.8 solves the issue.

Additional info:
* package version(s) 3.19.11-1
* config and/or log files etc: see attachment
* printer: HP_ColorLaserJet_MFP_M278-M281

Steps to reproduce:
1. update
2. scan for printer
3. error

Looks somilar to https://bugs.archlinux.org/task/64188

Look for a more recent driver at www.driverprinterdownload.com and check
upstream bugs at https://bugs.launchpad.net/hplip or file your own one there.

I found this link - https://forums.linuxmint.com/viewtopic.php?f=51&t=304796&sid=ff1f0bae89f87384a70d473d8c1fe7d6

In the file '/usr/share/hplip/data/models/models.dat', locate the section header
[hp_color_laserjet_mfp_m278-m281]


and remove the underscore between 'color' and 'laserjet'
[hp_colorlaserjet_mfp_m278-m281]

My printer magically reappeared, working once more, including scanning.
