Odoo POS | Add feature to the Point of Sales -- 2

Module for point of sale (POS). The Odoo POS module does not print a separate ticket for each item sold. This function is necessary for our festival. Required work : Adapt the POS module to allow printing of a ticket / voucher for each - sold item, for the same receipt. Concrete example : A customer buys 3 beers, a sausage and a bottle of wine. He will have to collect his purchases at different locations, but not necessarily at the same time. He will pay several beer, receive 5 separate tickets + the regular receipt (All cutted on ESC/POS PRinter) and go to get a first beer, then an hour later another, etc. <t t-name="PosTicket"> with <p style="page-break-before:always;"> is not working --> it modify only the view of the ticket. <t t-name="XmlReceipt"> --> that's probably the place (with js) to modify : but didn't success yet !
