=head1 NAME

C4::Print - Koha module dealing with printing

=head1 SYNOPSIS

  use C4::Print;

=head1 DESCRIPTION

The functions in this module handle sending text to a printer.

=head1 FUNCTIONS

=head2 NetworkPrint

  &NetworkPrint($text)

Queue some text for printing on the selected branch printer

=cut

sub NetworkPrint {
    my ($text) = @_;

# FIXME - It'd be nifty if this could generate pretty PostScript.

    my $queue = '';

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

    my $fh;
    if ( $queue eq "" || $queue eq 'nulllp' ) {
        return;
	#open( $fh, ">/tmp/kohaiss" );
    }
    else {

        # FIXME - This assumes that 'lpr' exists, and works as expected.
        # This is a reasonable assumption, but only because every other
        # printing package has a wrapper script called 'lpr'. It'd still
        # be better to be able to customize this.
        open( $fh, "-|", "lpr -P $queue > /dev/null" )
          or die "Couldn't write to queue:$queue!\n";
    }

    #  print $queue;
    #open (FILE,">/tmp/$file");
    print $fh $text;
    print $fh "\r\n" x 7 ;
    close $fh;

    #system("lpr /tmp/$file");
