Hex Code Printout

Hex dumps list all ASCII character data received from the host computer
with their corresponding two–digit hexadecimal codes. (Refer to the ASCII
character set page 4–40.) You can use hex dumps to troubleshoot printer data
reception problems.
Printable characters print as the assigned symbol; nonprintable characters are
indicated by the period symbol (.). The letter p before a hex code indicates an
active Paper Instruction (PI) line. A blank space before a hex code indicates
an inactive PI line.
NOTE: Control panel switch designations and configuration menu
