I had not noticed the priority difference before, but upon looking, I see
it.
And now I see a post in 2008 about this (and I said the same thing...)

But if you are having printer performance issues, this can be a giant"it
depends on what your doing" - but check (or elaborate) on the following:
a. what is the pool size in wrksyssts for *spool ? and the max active?
You will get better performance if the max active is so large as to divide
up the memory pool too much. Things like HPT need memory. So how many
printers active at once, and how much memory?
b. enough memory in the printers? Big print jobs to a production laser
w/minimum memory is always going to drag.
c. the zebras (again memory) but is it single labels or big batches? ZSPL or
other stream? Jet Direct or other print server in between?
d. are the spool jobs running through conversion processes (convert to pdf,
or add logos & reformat spool - all of this takes care in how subsystems are
allocated memory, and if jobs are rebuilding resources for every spool
d. Are the timeout values on the printers set according to IBM
recommendations?
Are the definitions older, using PJL drivers when perhaps snmp or ipp more
efficient?
The Redbooks for PRINTING IV, V, VI all had great detail on performance that
is still relevant today.

Subject: Question on printer priorities and classes
We have a situation where we are experiencing delays in reports and labels
taking a long time to get to the printer and be printed. This issue is
primarily with zebra printers.
Investigating the writers, I noticed when looking at split in WRKACTJOB that
some printers run at priority 15 and others at 50. This is something I never
noticed before.
The slow printers are running at priority 15 and the problem printers are
configured as LAN printers.
Does anyone know why some printers run at different priorities and use a
high priority value?
TIA.
