  3. # This script is intended to be used as a CUPS backend, to create
  4. # PDF file on-the-fly. Just create a printer using the device uri
  5. # pdf:/path/to/dir/. When printing to this printer, a PDF file
  6. # will be generated in the directory specified. The file name will
  7. # be either "<jobname>.pdf" or "unknown.pdf", depending wether the
  8. # jobname is empty or not.
  9. #
  10. # To use it, simply copy this script to your backend directory, and
  11. # create a printer with the correct URI. That's it.
