This is a Request for Quotation (or estimation) for the following functionality:
Upon an incoming order being accepted, the platform should communicate via mozilla web extension api with a native extension that acts as a server / driver to an ESC/POS compatible thermal printer.
The printing template should be separately configurable.
For templating, GitHub - xoe-labs/py-xml-escpos: Print XML formated receipts on ESC/POS printers, in Python. (or a similar lib) might be used (has frappe already a framework solution? How does Odoo currently handel ESC/POS templating?) The development should be capable of accessing any order model field, including custom field (which I think would be the framework’s default by design, but just in casr).
As for the native extension, inspiration might be drawn from https://fu.do native extension which uses (a variant of) GitHub - node-usb/node-usb: Improved USB library for Node.js for the USB bindings.
Please PM me or write me an email to firstname.lastname@example.org for an estimate.
Please post any questions here so I can clarify publicly.
Thank you very much in advance!
