#!/bin/sh
#
# This script is intended to be used as a CUPS backend, to create
# PDF file on-the-fly. Just create a printer using the device uri
# pdf:/path/to/dir/. When printing to this printer, a PDF file
# will be generated in the directory specified. The file name will
# be either "<jobname>.pdf" or "unknown.pdf", depending wether the
# jobname is empty or not.
#
# Usage:
#  1. Copy this script to your backend directory (/usr/lib/cups/backend)
#     and name it "pdf".
#  2. Create a printer in CUPS and use the URI "pdf:/tmp".
#  3. Optional: Install either mime-construct or mimeit (part of
#     metamail) to have the PDF files emailed instead of dumped to dir.
