Thermal printer template

is there a way one can set a different receipt template that can fit into a slim thermal printer instead of the normal printer that print A4 or Letter size?

Hi viny254, unfortunately this is not currently possible without editing the code, the functions for creating invoices and receipts are in the Finance/moduleFunctions.php script. Ideally, in future versions as we continue refactoring, these would become templates that could easily be edited with Twig, but we’re not quite there yet.
