PAX A920 Questions

1. Will the PAX 920 display the “PayPail” and “Vemo” QR code correctly for customers to scan and process payment. Linga Go does not display graphics.
2. Printer formatting. I can connect the POS via Operations/Hardware settings, to the internal PAX A920 printer. When printing the format looks like it is printing on a 31/8 wide printer. Is this correct. See attached image “PrintFormat1”
3. The PAX A920 would be deployed as a pay at the table device. Can there be a customer signature on the screen just like the Lings CDS.

Thank You.
