Surprised by the support from HP for its printers on Linux
my HP LaserJet MFP 135w goes to 2400 dpi using the HP provided driver (https://support.hp.com/us-en/drivers/selfservice/closure/hp-laser-mfp-130-printer-series/24494378/model/24494382?ssfFlag=true&sku= the file uld-hp_V1.00.39.12_00.15.tar.gz) and using simple-scan (https://gitlab.gnome.org/GNOME/simple-scan)

Printer-driver without scanning-functionality
The printer I'm using has excellent printing-capabilities from within Linux, however it fails completely, when it comes to scanning. I have tried Skanlite and Gnomes Document Scanner, but none of them lists the printer as a scanning-device.

I don't feel like I can help development, and I don't think it's just imposter syndrome
The Document Scanner project is not in the immediate list, so you need to click "Clone Repository" and enter https://gitlab.gnome.org/GNOME/simple-scan to get it up and running.

> So what do printers have to do with any of this?
The original post was about zeroconf, and therefore the later multicast DNS-SD based discovery protocol [1]. Namely aireplay, airport, airprint, airscan based protocols that multicast their functionality and protocols via DNS to the 224.0.0.251 (or [ff02::fb]) addresses (on port 5353).
Printers these days do have primarily support for airprint + airscan so they work out of the box on MacOS with all the GUIs that the OS has to offer. Not so much for WSD or other protocols that Linux/Windows still need. CUPS or ghostscript support usually isn't complete for anything else than TIFF, because nobody seems to give a damn about implementing a PDF rasterizer on-device, let alone gutenprint or postscript/ghostscript support for their scanner devices.
Reading through the sibling comments you have to recognize that my interpretation of "what is working" is a different one than a developer's perspective. If someone without programming/linux configuration knowledge cannot print or scan via WiFi, your tool is pretty much useless and didn't replace the 100 fragmented alternatives that existed before it already.
My complaints were mostly about avahi's integrated discovery tools like avahi-browse and avahi-discover which are only tools to discover printers, but are themselves useless for printing or scanning on their own (and they're not transport-level libraries for DNS-SD IANA registered protocols either).
Literally the only scanning tool that works in the Linux world is "simple-scan" [2], which requires preinstalled "sane-airscan" and an integrated avahi-daemon in the resolv.conf/nsswitch.conf. Don't ask about parallel IPv4 + IPv6 support, because that's totally unsupported and will crash in multiple NAT scenarios the daemon in an endless loop, and is the reason why every Linux wiki will recommend to add "mdns4_minimal" to the /etc/nsswitch.conf file instead of "mdns_minimal". [3]
Coming back to my point: I mean, every developer can send a postscript file via bash to an IPP port, but I wouldn't call it a working UX or UI. When comparing the aforementioned shitshow with how everything is nicely working on MacOS, Linux is basically a bad joke when it comes to mDNS support. I mean, the technology is almost 15 years old now, and we still can't have nice printer support on Linux.

A new, modern, and secure print experience from Windows
If your printer for example supports IPP and Postscript or PDF then that would be possible. Higher end (commercial) HP printers usually offer this functionality. Take a look at CUPS [1] if you want to know more about IPP.

Trying to set up an old Zebra LP2844 as a network printer
Your best bet is to set up a print server. The support page even has a CUPS driver. CUPS is well known for supporting a lot of printers. I run it on an old Mac-mini running Ubuntu. You can run it on something as small as a Raspberry Pi.

Microsoft to kill off third-party printer drivers in Windows
CUPS is under the Apache License 2.0 , so they can just use it, if they wanted: https://github.com/apple/cups/blob/master/LICENSE
They won't of course.

Is this easily solvable? I am going crazy
Another alternative is for you to set up a print server in VLAN20. Then set up the print server to print to the printer in VLAN99. CUPS is pretty easy to set up.

Sharing a Printer in a WiFi Network
But after both Apple and Linux switched their CUPS-based printing systems to Python 3 or some other breaking change that I don't mind to understand, the only way to print a document seemed to be using a PC running Microsoft Windows. So I had to save a PDF in the cloud or email it to myself, then startup Windows on a laptop physically connected to the printer, start the printing process, check if the paper has been printed successfully, and shut down Windows. What a waste of time and energy!

House upgrade: Need to keep an old USB-only printer connected wirelessly, would this work? (Old Router connected to new router)
Another option is to set up a print server. There are free print server programs that you can run on a computer. CUPS is pretty popular. I used to run it on a Raspberry Pi for an ancient LaserJet 1012. That printer just keeps going.
