                      3: # A sample backend script.

                      5: # The despooler opens the spool request and device.  It connects these files
                      6: # to THIS process's standard input and output.  Anything you send to
                      7: # standard output here is likely to end up on paper.  The "cat" command below
                      8: # transfers the request data to the device.  Notice how we put banners
                      9: # on the front of each request and how we ensure that the printer is at
                     10: # top-of-form for the next request in line.
                     11: #
                     12: # You can get as fancy or spartan as you want insofar as banners are
                     13: # concerned.  Business users in particular hate banners because they
                     14: # consume paper.
                     15: #
                     16: # You can also use this backend as an opportunity to transform the raw
                     17: # report text in some way before you write it to the device.

                     23: #    $3 = number of copies
