[Python] IPP printer python

I have a somewhat ambitious project idea. Custom printer. But I cannot for the love of god find a way to emulate an ipp printer in python. No, this is not a dupe. My first goal is to create a python program, that acts like a printer, and saves the .ps files to a location.

I found a github repo called ipp-server.

But when I cloned it, the ps files that the printer saves are corrupted. I get the error below when using ps2pdf:
