What can I use the printer port for on the Midrange MI HMI?

The port is a standard 25pin Centronics printer port. It offers support
for a line printer, which can be used to print log entries, either the
whole log in one go, or entries as they happen. There is no support for
modern laser or inkjet printers, since no printer drivers exist within
the HMI. Logs can be extracted however through the serial ports.
