It *is* a valid method, and you should be getting valid raster data.

Try redirecting your print queue to file:///tmp/printername with:

     cupsctl FileDevice=Yes
     lpadmin -p printername -v file:///tmp/printername

and then examine the raster data that is put in that file when you
print.  My RasterView program is useful for this:

re-posting your questions...)
