How To Customize Waybill Copy Labels

Code goes to your active theme’s functions.php file:

function wpcargo_custom_waybill_copy_labels_cb($copies) {

    // alter accounts copy

    $copies['accounts-copy'] = __('Altered Accounts Copy', 'wpcargo');

    // alter consignee copy

    $copies['consignee-copy'] = __('Altered Consignee Copy', 'wpcargo');

    // alter shipper copy

    $copies['shippers-copy'] = __('Altered Shippers Copy', 'wpcargo');

    return $copies;

}

add_filter('wpcargo_custom_waybill_copy_labels', 'wpcargo_custom_waybill_copy_labels_cb', 10, 1);
