Testing Printer and Host Communications
This is a simple test of
To test host-to-printer communications
1.Switch the printer power off. Return the DIP switch settings to the standard configuration if they have been changed.
2.Press and hold the Feed/Pause button while powering on the printer. The printer presents the hardware configuration test label.
3.Release the Feed/Pause button after the hardware configuration label is printed. You are now in data line print mode within the Test and Service mode.
4.Send down some characters from the host. At this point the printer does not attempt to interpret any printer commands, but simply prints each character and its hexadecimal equivalent as it is received. If you are using a PC running DOS, send down the following strings of commands from the DOS prompt:
Note: ^Z is [Ctrl] [Z].
\MODE COM1: 96,E,7,1,N [Enter]
(to configure the serial port)
\COPY CON COM1: [Enter]
(tells the PC to copy the following text to the COM1 port)
ABCDEF^Z [Enter]
(these characters are sent to the printer)
