3-3. Switch Operation (Combined Switch Operation)
1) <SELF PRINTING>
FEED + POWER ON (Turn the power on while holding the FEED switch depressed.)
2) <Hexadecimal dump mode>
ON LINE + POWER ON (Turn the power on while holding the ON LINE switch depressed.)
Each of the signals sent from the computer to the printer will be printed out in hexadecimal code.
This function allows you to check if a control code sent to the printer by the program being used is correct or not. The last line is not printed if its data is less than one full line. However, if the ON LINE switch is pressed to set the off line mode, the last line will be printed. To turn off the mode, it is necessary to turn off the printer completely.
