VERVIEW
Normally a printer prints character patterns that correspond with 
the input character code. The printer does not print function 
codes or invalid codes. If the printer does not operate normally, 
the data sent from the host computer must be checked to 
determine if the commands are correct.
In this mode the printer converts input data into hexadecimal 
data and prints all the input data, making it is easy to check all 
the codes sent from the host computer to the printer.
