General Description
Hexadecimal Dump Function
You use the hexadecimal dump function to check the data the printer is receiving
from the host. To turn on hexadecimal dump mode, turn on the printer while
holding down the LINE FEED and FORM FEED buttons. In hexadecimal dump
mode, the printer prints the hexadecimal representation of the input data and the
corresponding ASCII characters. If input data is a control code instead of a
character code, the printer prints a period (.) in the ASCII column.
