  34 C4::Print - Koha module dealing with printing

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

  47
  48   &NetworkPrint($text)
  49
  50 Queue some text for printing on the selected branch printer

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

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