Summary and Info: On a functional, up-to-date system, with cups, most foomatic-db packages, hplip and avahi installed, I tried to print a small text file on a previously functional printer.
lpr responded, the task appeared in lpq, but never terminated, printer gave no output. On checking the cups administration pages, I discovered to my dismay,
that apart from the `start' page under local:631, all underlying pages were completely _empty_.

Steps to Reproduce:
All packages mentioned above have been removed, and re-installed multiple times, in different orders, all yielding the same result. did not mention any similar bugs, so to no avail. system-config-printer showed printer and allowed underlying parameters to be
Apart from a re-installation from scratch, my box of tricks is empty.
N.B. My office is by and large paperless, this printer is used about ten times a year; this may very well be the result of
a system update, albeit not necessarily the most recent one.
This task depends upon

Update Sept. 19

Although Cups still presents the `empty screen' I have made some progress: The command within hp-setup to retrieve a key
failed initially; I lifted the command string from the screen, edited it and then ran the command successfully. Next I ran hp-setup as root without the -i flag -- the program complained about both! -- and managed to download a functional plugin from HP's website
(Not a particularly clean approach, I admit!).

As a consequence the printer finally produces some output; Lpq and lpstat enable sensible access. Localhost:631 pages
still empty, though, so no printer administration possible from within cups. But at least the cups-pdf filter works.
