Hex Code Printout
Hex dumps list all ASCII character data received from the host computer
with their corresponding two–digit hexadecimal codes. You can use hex
dumps to troubleshoot printer data reception problems.
Printable characters print as the assigned symbol; nonprintable characters are
indicated by a period [.]. 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.
