There are some software packages that let print jobs build up
in an internal queue, then issue dozens of rapid-fire lp commands
to print them. Certain configurations of the SAS software will
do that. Also, once in a while on large servers, you'll get a
bunch of people who all decide to print at the same time.
It's not a universal problem (i.e. not everyone sees it), but it
is seen by sites that have bursty patterns of printing.
