Ok, so in that case the only changes are udev and copying the
system. You have the device, with sensible ownership, so I now
think the copy must have done something wrong in the cups
files/permissions. And I repeat: have a look at the queue on the
cups server to see if it the print is still waiting.

1.2.7 was announced at cups.org on November 16th, so I think it's
still pretty recent, but I accept you might have been using it for
over a month before you copied the system and upgraded udev.
And I repeat - mount the old system somewhere, and compare the cups
files (contents of the conf, and permissions).

Nothing like mine - here's the start of my cupsd.conf from 1.2.7

I don't have anything explaining the options, which makes me think
you got your cupsd.conf from an older version.

Did I say it would work like that? I said that my_experience is
with using File|Print. Maybe there is some sort of --pretty-please
switch you could pass to lp/lpr, but I wouldn't know.
I still don't think udev is the problem, but your mind seems to be
made up about that, so we'll just have to agree to differ. I've
seen catastrophic udev failures when I tried to upgrade it on a
running system, but every indication is that your new udev is
