I recently wrote a  user space CUPS driver for a thermal printer. At the 
point I get to process the print data it has already been rasterised 
into a bitmap. My impression is that CUPS takes whatever it is given to 
print and either passes it transparently to a device that can handle it, 
e.g. a pdf printer,  or rasterises it and passes a bitmap.

I did not see any sign that CUPS goes through an intermediate PDF or PS 
stage.

Also of note is the entire CUPS API is deprecated. I'm not sure what is 
to replace it but whatever it is, it is not mainstream yet.
