I am looking for a public domain program that converts a postscript file into something that can be fed into a Kyocera printer (Basically HPLJ). Is there something around that does not need to convert the postscript-file into a pixel representation?

There is a real problem converting PostScript to HP-PCL, the language of
the HPLJ. First off is the scalable fonts. No scalable fonts on the LJ.
Any font size needed must reside on the cart installed or as a downloadable
font. The LJ can't possibly handle the number of possible font sizes and
font families (about 35 fonts are standard on a PostScript printer). The
program could scan the PostScript document and load as many as possible,
or load in what is needed on a per page basis. Damn, that would be slow.
The other problem is the drawing capabilites of PostScript. The LJ has
nothing to do drawings like PostScript can. If any arcs were called for,
the LJ would be lost.
Looks like bit-map conversion to me.
The above are my opinions after working with both types of printers.

It has drivers for various displays/printers. The rendering is fast, but the size of the file produced for an HPLJ printer may make the actual printing slow (though performance improves by using a parallel connection rather than serial). You can get the latest version (2.1.1) from prep.ai.mit.edu in the pub/gnu directory. You'll want to pick up the files ghostscript-2.1.1.tar.Z and ghostscript-2.1fonts.tar.Z. Mark
