Ideally your printer advertises itself via Bonjour/Avahi/SLP or whatevs. Ideally Windows receives these adverts and connects you to your printer. One or the other gets it wrong, with monotonous regularity.

IPP is print anywhere and it sounds like its been branded "Mopria".

I ditched a thing called HPLIP at home at least five years ago which used to be the cutting edge for Linux printing on HP printers. The bloke that developed CUPS said it was a good idea and I went for it.

Now it just works - always. It sounds like Windows is catching up, finally.

Of course, not all routers (particularly combo router/modems provided by your ISP) support multicast DNS, so often this isn't an option.

I haven't seen a home router that doesn't support Bonjour in the past decade. It's a fundamental component in the Apple ecosystem and any home router that didn't allow one to wireless print from their iPhone would be considered broken.

Do people really wireless print from their iPhone? Not once can I say I've wanted to print from my phone.

Yes iphone wireless printing works great esp PDF attachments in emails. I use it quite a bit.

The router doesn't really need to support anything, the mDNS packets just flood the bridge domain directly between clients like any other flooded packet.

That’s the nice thing about mDNS. No flooding of anything since it’s multicast and not broadcast.

It would be nice... if it were actually "real" multicast :). It's instead link-local multicast, which has none of the filtering advantages of traditional IP multicast (i.e. no group joining via IGMP is performed for the switches/routers to be able learn who actually needs to listen) https://community.cisco.com/t5/switching/route-igmp-link-loc... https://community.cisco.com/t5/switching/multicast-on-the-la....

The advantage of link-local multicast over a plain broadcast is it gives a unique address (IP and multicast) so the clients themselves can more easily filter them. That's about it.

Starlink routers don't forward mDNS packets between clients, and neither did our Fios router before that.

Airprint and Mopria are the same thing, IPP + discovery.
