pdq is a non-queueing printing system -- the assumption being that
in most places, there isn't all that much contention for the printer,
and it will usually be available for printing.  so you print your
job, and if the printer isn't available it is retried for a while, but
then the command gives up -- after all, you'll go fix the printer, or
find out what's wrong, and try again.  it saves a copy of your job
in your home dir for a while (days) in case it's hard to reproduce,
but it won't be retried.  there's no central queue or spool of print
jobs, and no central server.  every client just tries the printer
directly.  (i think the "printer" can be an lpd server, but i'm not
sure.  but this is external to pdq.)

i used it for years at home.  now that i've upgraded all of my machines
to recent ubuntu releases, and pdq isn't apt-available, i'm running
CUPS, and it sure feels complicated in comparison to pdq.
