Two different problems on the box and resulted in the crash of the Odoo instance running on the IoT Box: When `usblp` had troubles communicating with a printer, a NoDeviceError was raised. The `printer` variable was still set from the last time the loop was processed, so we tried to close it, resulting in an error. The code handling generic execptions was broken. closes odoo/odoo#34300 Signed-off-by: Quentin Lejeune (qle) <qle@odoo.com>
