Order barcode in print

It is sort of out of scope of this plugin. The plugin supplies a couple of hooks that you can use do basically anything you like. Be it a barcode or an image of an elephant ??

Anyhow, maybe I can help. Can you supply:

• The barcode plugin you are using
• Any errors you get (have WP_DEBUG on in wp-config.php?)
• A snippet of the code you are using and in which file this is?

Hi,

Try to add the following code to your child theme/woocommerce/print-order/print-content.php

<?php
echo WC_Order_Barcodes()->display_barcode($order->id);
?>

NOT the following one:
<?php
echo WC_Order_Barcodes()->display_barcode($order_id);
?>
