Another example is managing a shared, platform heterogeneous
distributed printer database. Linux LPRng software from the
distributors works out of the box, simply by copying a common printcap
around. We have to compile and support LPRng for AIX ourselves, and
disable the native qconfig. We could copy qconfig files between AIX
boxes, but certainly not to any non-AIX platform like solaris, hp-ux,
or linux.
I use cups. Printers come and go on my Linux laptop, according to where
I go. CUPS servers can be configured to chat to each other, and my Linux
(and OS X) laptop runs CUPS.
Printing on Linux works as well as wireless on OS X.
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.
I can understand that if you're running Ghostscript, then you're in for
some trouble.
I think you'd need to pay close attention to how (often) the CUPS
servers talk to each other, too. If they're discussing 10,000 printers
every few seconds. The default browseinterval is 30 seconds, that might
be a little often.
