Datascope Mode allows the user to test the printer’s communications. When in Datascope

prints them out on receipt paper as hexadecimal numbers in the order received. For
example, the ASCII character “A” is printed as the hexadecimal number 41 an so on.

1. After you have enabled the Datascope Mode through the Configuration Menu, exit the
Configuration Menu.
2. Run a transaction from the host computer.
All commands and data sent from the host computer will be printed as hexadecimal
numbers as shown in the illustration.
