  33 C4::Print - Koha module dealing with printing

  39 =head1 DESCRIPTION
  40
  41 The functions in this module handle sending text to a printer.

  45 =head2 NetworkPrint
  46
  47   &NetworkPrint($text)
  48
  49 Queue some text for printing on the selected branch printer

  59
  60     # FIXME - If 'queue' is undefined or empty, then presumably it should
  61     # mean "use the default queue", whatever the default is. Presumably
  62     # the default depends on the physical location of the machine.
  63     # FIXME - Perhaps "print to file" should be a supported option. Just
  64     # set the queue to "file" (or " file", if real queues aren't allowed
  65     # to have spaces in them). Or perhaps if $queue eq "" and
  66     # $env->{file} ne "", then that should mean "print to $env->{file}".

  76         # This is a reasonable assumption, but only because every other
  77         # printing package has a wrapper script called 'lpr'. It'd still
  78         # be better to be able to customize this.
