Add printer in LAN mode by IP address

[rkarlsba]

Since the WAN mode is utterly insecure, adding a printer by its IP address would be nice in LAN mode when mDNS isn't available. Either because the printer is on a different subnet and the router doesn't route multicast, which is quite normal or if you have an enterprise wifi system (for instance from Cisco), which also may drop mDNS.

Multicast being blocked between wired and wireless connections is fairly common even on consumer/SOHO devices, so this would be nice even just for better connectivity.

i have multiple vlans and adding the printer via ip would be awsome. mDNS is pain in the ass for subnets...

Not sure why this wasn't done in the first place... definitely a must-have!
Bambu appear to have implemented Multicast SSDP instead of mDNS, Which is a shame as Avahi does not support this.

From Wikipedia [SSDP] was formally described in an IETF Internet Draft by Microsoft and Hewlett-Packard in 1999. Although the IETF proposal has since expired (April, 2000),[1] SSDP was incorporated into the UPnP protocol stack, and a description of the final implementation is included in UPnP standards documents

Doesn't seem very sane to use with anything, tbh.

Even fallback to regular DNS would be an improvement - I can always setup a local DNS entry for the printer..

Which reminds me that IPv6 support would be nice. Seems the printer is running Linux after all, so it really can't be that hard.

That explains why i cant get the Printer working in lan mode in my vlan network… i should have used wireshark in the first Place…

pls bambu: add „printer by ip“ support

You can remedy that by enabling multicast routing or forwarding between VLANs if the router understands that sort of stuff. Still, adding by IP or DNS name shouldn't be very hard to fix and is the good solution to this.

As a temporary solution. I've written a script to generate an unsolicited response to the upnp/ssdp discover, to tell BambuStudio the IP of the printer. It's meant to be run on Linux, but may work on Windows too if run in a VM/Container/Cygwin.

It has to be run each time BambuStudio is restarted, as Bambu will forget until it receives the response to its M-SEARCH ssdp:discover.

[rkarlsba]

Better fix this in source. Such workarounds just make Bambu relax since "there's a workaround". The Bambu printers aren't cheap and this should be easy to fix.

Lots of fixes and improvements with v1.4 but this one is still missing.

[rkarlsba]

Can it really be that hard?

With today's outage, this is now especially pertinent. There is already an existing dialogue for this feature as of 1.4.2 -- there should be very few blockers for this now.

My thoughts on this.
It should not require an app using bluetooth to set up the printer for LAN mode. The selection for lan mode should always be available.
After selecting LAN mode only there needs to be a way to connect the printer to the network. A simple way would be to allow putting a file "network credentials.txt" on the SD card and the printer can use network name and password from that file to connect to the network.

When the printer connects to the network it should display its ip address and passcode for bambu studio to connect to it. I am not a network expert so I am not sure about broadcasting its availability on the network. I think this should be okay on a LAN, which makes it discoverable without having to type in the IP address in bambu studio.
