ITA - Buoni pasto e registratore telematico

This module connects the Point of Sale meal voucher feature with the Italian fiscal printer. When a payment is made with a journal whose fiscal printer payment type is '4' (tickets with number), the payment screen shows a Tickets N. column with plus and minus buttons so the cashier can set how many vouchers are used. Each ticket payment line starts with 1 ticket by default.

Before validating an order, Odoo checks that the total paid with tickets does not exceed the order total; if it does, an error popup 'Wrong tickets total' appears and the order cannot be validated.

If the vouchers received are more than the eligible amount and there is change, a button 'Issue ticket credit' appears. Clicking it adds the configured 'Ticket credit product' to the order for the change amount, so the customer gets credit instead of cash change. If no ticket credit product is configured in the Point of Sale settings, an error popup asks to configure it.

The number of tickets is stored on the POS order and passed to the generated bank statement line, where it is shown as 'POS tickets number' (read-only, hidden when zero). In the Point of Sale configuration, a new field 'Ticket credit product' lets you choose which product is used for this credit; only products available in POS, saleable and marked as meal voucher OK can be selected. The journal also automatically sets the fiscal printer payment type to '4' when the meal voucher type is 'paper'.
