Comment 5 for bug 1819742

Hi,
i note that this printer doesn't need any plugin :

Model Name Min. HPLIP Version Driver Plug-in
HP LaserJet Pro MFP M28a 3.18.4 No

But after a fresh installation of HPLIP, at the first scan i receive a message asking for plugin download and installation plugin.

models.dat contains:
