I think, I understand now, what I really meant:

https://en.wikipedia.org/wiki/Web_Services_for_Devices

The idea is to have all the printers in its own VLAN and then having a
proxy, like ipp/cups, so that the devices can be shared / exported
into other VLANs on a single service point.
My web search was not successfull if such a "WSD proxy" already exists, but
there are some WS discovery implementations in python,C and java.
This WSD protocol seems not to be used very often, given that there are so
few problem reports, or its working very well, but I doubt that.

The Windows GUI supports adding "Web Service Device" in the Add printer
wizard "using TCP/IP" address, and it seems its possible to add it with
powershell too:

Additonally there is some "StableWSDiscoveryEndpoint" in the
WSDPrintServiceV12 document, but as said, I haven't found anything working.
So there is no "WSD proxy", like ipp/cups.

best regards,
