How many pages? Embedded pictures with high resolutions?

What happens if you use Acrobat to "Save As..." under a different name?
Does it then shrink considerably in size?

A job title starting with "smbprn.000" is an indication for the job
having arrived via Samba, not Mac OS X. Mac OS X would talk CUPS-to-
CUPS and IPP, no?

OK, this means CUPS doesn't see any specific job options. The job-uuid
is a recent addition to CUPS; the universally uniq job ID is automatically
tagged to the job by CUPS to be able to track jobs that touch different
CUPS servers (where traditionally the job-id is a simple counter, that can
easily lead to same job-ids for neighbouring CUPS servers [or clients with
their own spooler process] where jobs are in fact different ones).

This makes re-producing your problem a bit easier, because you do not need
to take them into account.

The only other variant may be the specific settings in the Acrobat print
dialog your users may have used.
