I want to concentrate on the change in ppd file on upgrading from Squeeze
to wheezy because it appears to me to be the essence of the bug report.
It may also be deserving of a higher severity level than "important" but
I will leave that on one side for the present.
The bug appears on upgrading because packages printer-driver-hpijs and
printer-driver-hpcups are both installed and the hpcups updater file in
/usr/share/cups/ppd-updaters/ is run before the one for hpijs. This,
however, is not the fundamental origin of the bug.
My attempt to make progress towards a successful solution of this bug
follows.
Testing procedure.
------------------
1. Implement a fully up-to-date Wheezy machine.
2. Create a print queue with
lpadmin -p TEST-HP -v file:/dev/null -m drv:///hpijs.drv/hp-deskjet_f300_series-hpijs.ppd
3. Delete the hpijs and hpcups lines in /var/cache/cups/ppd-updates.
This (I think) replicates the situation when a Squeeze/Wheezy update
place.
4. Sprinkle /var/lib/dpkg/info/cups.postinst with a few echo statements
like
echo $driverregep is driverregep
5. Then
apt-get --reinstall install printer-driver-hpijs
The screen output I get is:
root@testing-cups:~# ls -l /etc/cups/ppd/

The bug appears to reside in cups.postinst or the updater files for hpijs
and hpcups.

Brian.
