CUPS is a great workstation printing solution.  I use it on all my
personal workstations.

Unfortunately, in my testing, it isn't so good an enterprise printing
solution.

In particular, when I tested it with our database of 10K printers,
printing from enterprise class hosts on about 20 subnets to central
print servers on different subnets, it simply broke.  It never
finished distributing the printer database, and the central print
servers went CPU bound and were unable to process jobs.

This was two years ago, and two years is a long time in the open
source world, but none of the updates I've seen from CUPS over this
time have addressed these scalability issues.
