 209 =head1 NAME
 210
 211 labels/label-create-pdf.pl - A script for creating a pdf export of labels and label batches in Koha
 212
 213 =head1 ABSTRACT
 214
 215 This script provides the means of producing a pdf of labels for items either individually, in groups, or in batches from within Koha.
 216
 217 =head1 USAGE
 218
 219 This script is intended to be called as a cgi script although it could be easily modified to accept command line parameters. The script accepts four single
 220 parameters and two "multiple" parameters as follows:
 221
 222     C<batch_id>         A single valid batch id to export.
 223     C<template_id>      A single valid template id to be applied to the current export. This parameter is manditory.
 224     C<layout_id>        A single valid layout id to be applied to the current export. This parameter is manditory.
 225     C<start_label>      The number of the label on which to begin the export. This parameter is optional.
 226     C<lable_ids>        A single valid label id to export. Multiple label ids may be submitted to export multiple labels.
 227     C<item_numbers>     A single valid item number to export. Multiple item numbers may be submitted to export multiple items.
 228
 229 B<NOTE:> One of the C<batch_id>, C<label_ids>, or C<item_number> parameters is manditory. However, do not pass a combination of them or bad things might result.
 230
 231     example:
 232         http://staff-client.kohadev.org/cgi-bin/koha/labels/label-create-pdf.pl?batch_id=1&template_id=1&layout_id=5&start_label=1
