3.7 Hexadecimal Dump
1) Hexadecimal dump function
This function prints the data transmitted from the host in hexadecimal numbers and their
corresponding characters.
2) Starting hexadecimal dumping
Open the cover and turn the power on while pressing the receipt paper feed button. When the
receipt paper feed button is released after approximately 1 second (if the DIP SW2-3 is On, the
printer beeps twice shortly) and close the cover, the printer first prints "Hexadecimal Dump" on roll
paper and prints the received print data in hexadecimal numbers and in its corresponding
characters.
NOTES:
1. Be sure to execute the hexadecimal dump in setting with the paper.
2. Set the printer in the hexadecimal dump first; then transmit the data from the host.
3. "." is printed if no printable character corresponds to the data received.
4. During the hexadecimal dump, all commands except DLE ENQ is disabled.
3) Ending hexadecimal dump
End the hexadecimal dump by turning off the power, by pressing the receipt paper feed button three
times, or by resetting the printer after printing completes.
