-Implemented a WebSocket service to facilitate communication with the IoT box. This enables printing reports on a network different from the browser. Before it was a long polling connection -Implemented the ability to link multiple printers to a single report. Before it was possible to link only one printer er report -When multiple printers are linked, a pop-up will prompt the user to select the preferred printers. -The user's printer selection will be stored in the browser's local storage. -Additionally, a reset button has been added to clear the printer selection. task-3193258 closes odoo/odoo#129164 Related: odoo/enterprise#44398 Signed-off-by: Quentin Lejeune (qle) <qle@odoo.com>
