To aid in the configuration and troubleshooting of a Zanasi Z4xx printer, the following changes were made.

The F2-Test Print function has been re-enabled, to make it easier to troubleshoot or verify RS232 communication between the 6370 and the printer.

The Printer Status screen will now repeatedly request the 6370 software version so that the TX count and the Err Count fields in the Printer Status screen can be used to verify RS485 communication between the XL and the 6370 board.
