OK, I don't know what to make of this:

I downgraded cups to 1.3.8-1lenny2 (the original, hanging version),
tried printing two of the complex formerly problematic documents,
didn't get any socket backend hangs this time (with printer "test"
which remained configured exactly as last time when it did produce hangs).
Verified timestamp of socket backend binary, was ok (October, matching
distribution package, _NOT_ my custom-patched package version),
and of course I had stopped and started cups, repeatedly even.

Then I said "so what" and upgraded to incoming.debian.org 1.3.9-5
(plus _all_ cups helper packages),
first submitted job got stuck at first page without producing any
printer traffic, second job worked fine.
(first job could possibly have been confused by an earlier Job
Abort button action at the printer, though)

Puzzled.

Thanks a lot for your work,

Andreas Mohr
