Direct Print for Point of Sale: ESC/POS Receipts Without IoT Box

In standard Odoo, a POS receipt printer must be an Epson ePOS model or sit behind an IoT box, and a USB thermal printer only prints through the browser print dialog. This app lets the Point of Sale print on any ESC/POS printer the Direct Print agent can see, in USB or on the network: the receipt prints and cuts itself after payment, with no dialog.

1. Install the Direct Print agent on the computer the printer is plugged into, and declare the printer with the ESC/POS language.
2. In the Point of Sale, create a printer of type Direct Print and pick the thermal printer of the agent. Set the paper width and the cash drawer, then print a test ticket.
3. Add it to the receipt printers or the preparation printers of the shop, and choose an invoice printer if the till should print invoices instead of downloading them.

Any ESC/POS thermal printer: Epson, Star, Bixolon, Xprinter, Rongta and others, on 58 mm or 80 mm paper, connected in USB, through the system print queue or in raw TCP on port 9100. The ticket is sent as an image, so every character set prints, Arabic and Chinese included, with the logo and QR code of the standard receipt.

• Kitchen tickets go to the preparation printers, per product category.
• The cash drawer opens on a cash payment, a cash in or out, and at the opening and closing of the session.
• Other tickets: the sales report, tips and cash moves of the session.
• A tablet on Wi-Fi can print on the USB printer of the back office PC: the till only talks to Odoo.
