I believed that CUPS stack is based on PDF while earlier PostScript

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.
