Appendix D: Interface Data
From the printer’s send loop, hexadecimal characters from 20H to
7FH are transmitted into the receive loop. These characters are
stored in the buffer and printed.
This process is repeated until the printer is turned off. The printer
returns to normal operation when you set the Diagnostic Test
menu option to No.
To set the printer to menu mode while the Diagnostic Test option is
set to Yes, hold the menu key down while switching the printer on.
