Just discovered it is a problem with hplip driver. You have to run the hp-setup utility so that the proprietary MFP driver plug-in is reinstalled:
$ sudo hp-setup
This is a workaround.
Should the hplip package install the proprietary plug-in automatically during the upgrade since the EULA was previously accepted?
Should the user be asked to accept the EULA and get the plug-in installed during the dist-upgrade to precise?
