`Hello,
I have managed to implement this recently. It has nothing to do with wePOS. But you will need a few things.
First, <a href=”https://codecanyon.net/category/wordpress?term=printnode” rel=”noopener” target=”_blank”>this module </a>to connect to printnode’s cloud printing service.
Second, register with printnode to get their API credentials and also download the client. This one you must install on the computer to which the printer will be connected (you can use almost any printer, but printnode has a compatibility section if you want to be sure).
The module will do the job once you have configured it, it prints all incoming orders, including the orders generated through the POS.
