I've got a two printer (formerly three!) "cluster"/pool, works great.
Here's a sample of my config.
We have two big IBM Infoprint 40's, CR01 and CR02. CR00 is the pool
name, and the job automatically goes to the least busy printer.
For a while we had three printers in this pool. We would print 22,000
page jobs by splitting the job into 500 page packets, creating a
custom banner page, and then spooling all the packets to CR00. LPRng
would then distribute them evenly between the three printers.
3 printers running at 40 pages per minute = 120 PPM! It rocked! The
22k page job would run in just over 3 hours instead of 8+ hours.
If you'd like additional information regarding our funky z option
form definitions and print pooling, let me know.
