That depends entirely on the system you use.

We regularly test configuration with 10000 queues to ensure that CUPS
can scale that large, however actual performance will depend on the
type of printers used, how they are connected, and the CPUs, memory,
and disk you have.

We used to have an "estimator" page on the easysw.com page which
provided guidelines for CPU, memory, disk, and configuration options.
I'll look at getting this page up on cups.org...

In the meantime, you'll find that PostScript printers require less
CPU and memory than non-PostScript printers, and you can use the
FilterLimit directive to control how many jobs are printed
simultaneously.
