You can choose as many printers as you like, using the settings in your WordPress dashboard in WooCommerce -> PrintNode -> Settings:
If you want to filter orders in a more complicated way, so that orders go to a printer only sometimes (depending on something to do with the order itself) then you will need to do a little custom PHP development for this, in order to implement the logic of your particular requirements. (i.e., you’ll either need to write a little PHP code yourself, or hire a PHP coder – somewhere like codeable.io or freelancer.com is an option if you don’t already have a developer. Please note that customised development isn’t part of your plugin purchase – i.e. we can’t contribute time to do this for you as part of your purchase. However, we’ve done 90% of the work for you, below).
The way to do it is to use the woocommerce_printorders_printnode_copies filter. Using the passed parameters, you can apply arbitrary criteria based upon anything you like concerning the order. Here is a code fragment to start your developer off with:
<?php
add_filter('woocommerce_printorders_printnode_copies', function ($copies, $order, $printer_id, $source, $source_info, $printers) {
// Get the order details
$order_meta_data = $order->get_meta_data();
/*
Do something based on the order, according to what you require...
if ($order_meta_data['key'] ... ) {
// Suppress this print job (print no copies)
return 0;
}
*/
// If our conditions did not match, then leave things as they were
return $copies;
}, 10, 6);
Alternatively, to suppress all automatic printing (so that printing is manual-only):
add_filter('woocommerce_printorders_printnode_print_on_payment_complete', '__return_false');
add_filter('woocommerce_printorders_printnode_print_order_now', '__return_false');
