Most printers only accept a single connection at a time, so the output order will be mostly random between servers depending on the load. You can run an extra cupsd (that doesn't share its printers) for the common printers and point the external cupsd's at the internal server to get "fair" scheduling of jobs, although that will make job control a little more complicated.

Unfortunately, this kind of configuration is rare enough that we haven't been able to justify the amount of time (or added complexity in CUPS) to implement it, especially when running multiple cupsd instances solves the problem.
