There used to be a timeframe (before like 2020) where you could use network printers without any extra software: Open your Document in Firefox, print to postscript, and then netcat that postscript to your network printer port 9100. This is the "AppSocket" protocol. Unfortunately, Firefox removed that feature, and port 9100 is now clobbered by the Prometheus node exporter. If you accidentally add a AppSocket capable printer to Prometheus it will print out HTTP headers every other minute. The good times are over, but on the other side, having to print something has gotten quite rare.

Now we have something better, IPP everywhere. The protocol isn't as simple as netcating a postscript, but is simple enough, standardized and does everything expected for printing.

  Is there a implementation for Linux that isn't cups?

    There are a few clients here: https://github.com/topics/ipp https://github.com/topics/ipp It's not hard to write a client library / CLI, it's just there isn't much interest.
