Thanks for the quick answer.
Running multiple instances is simple for this example.
As soon as you have more networks and printers need to be visible in several of them it gets really messy with multiple instances.
Example:
printer-a visible in net-a and net-b
printer-b visible in net-b and net-c

This would lead to 3 instances with printers getting jobs from 2 instances at the same time.
Even worse for more complex setups.
Are there any problems to be expected when I have one printer getting print jobs from multiple cups instances/servers at the same time? (thinking about 5 instances/servers hitting the printer with 20 larger jobs each. Would it not be quite random which job gets printed at what time?)

I wish there was a clean solution for that.
