What I want as a result is the ability to reprint a pos order after the validation (set to paid).
Since I don't have a Ethernet thermal printer but just an USB one and I can't set a proxy printer, I need to exit the POS, enter the order and use the "reprint" button. Luckily, since I've installed the Report to printer module I am able to print directly to my thermal printer when I press the button.
I've already installed the modules Automated Action Rules and now I'm begging an help to identify the correct workflow and the syntax to reprint.
Edit:
Please have a look here for a workaround: bind a report to a workflow
