  36 C4::Print - Koha module dealing with printing
  37
  38 =head1 SYNOPSIS
  39
  40   use C4::Print;
  41
  42 =head1 DESCRIPTION
  43
  44 The functions in this module handle sending text to a printer.

  46 =head1 FUNCTIONS

  48 =head2 NetworkPrint
  49
  50   &NetworkPrint($text)
  51
  52 Queue some text for printing on the selected branch printer

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

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