You can print multiple copies of an order to the same printer by adding the following snippet to your website:
function sl_cc_printus_print_multiple_copies($job_data){
$job_data['qty'] = 2;
return $job_data;
}
add_filter('printus__printnode_job_data', 'sl_cc_printus_print_multiple_copies', 10, 1);
The code above will generate two (2) copies per printed order. You can change the value to the number of copies that you want per order by changing 2
to the number of copies that you want.
Note: You can usually change the number of copies your printer produces from it’s “Printer Properties” settings without needing to use the code above.
