Following are notes about my experiences and impressions using HPLIP
updates. These notes are informational; you are not expected to respond.

One of my customers ran this on his Zentyal server. Using the (i) remove
and install option caused Zentyal to disable its Office --> Printer Sharing
management module. When the Printer Sharing module was reenabled in
Zentyal, it reinstalled the old version of HPLIP from repositories. Newer
printer definitions were retained, I think, but the new HPLIP code base was
reverted. Maybe (o) overwrite would be the better choice, but I haven't
tested all this?

I question whether the HPLIP installation procedure works correctly in an
Ubuntu repository environment. My impression is that the user installing
HPLIP is assumed to be an omniscient expert, and so very little guidance is
provided. On the other hand, I know perfectly well that no one reads
documentation anyway, so any guidance would have to be written into the
installer.

Mostly, I think I need HPLIP for missing and updated printer definitions,
and the code update itself is not that important. Could these two parts be
unbundled, providing a package for printer definitions separate from the
HPLIP management code which requires code compilation and so forth? This
might work better with the Ubuntu repository approach, as an updated set of
printer definitions might  be generalized and not require compilation, and
could be applied as fixes to older versions of repositories.
