Hexadecimal Dumping
Hexadecimal dumping function
This function prints the data transmitted from the host computer in hexadecimal numbers and
in its corresponding characters.
Starting hexadecimal dumping
Open the cover and turn the power on while pressing the RECEIPT FEED button, then close the
cover. The printer first prints “Hexadecimal Dump” on the paper roll and prints the received
print data in hexadecimal numbers and in its corresponding characters.
Notes
❏
If no characters correspond to the data received, the printer prints “.”.
❏
During hexadecimal dumping, any commands other than DLE EOT, DLE ENQ, and GS ENQ do
not function.
Ending hexadecimal dumping
Hexadecimal dumping ends by turning the power off or resetting the printer after printing has
finished.
