Printing a Hex Dump
A hex code printout (or hex dump) is a translation of all host interface data to its
hexadecimal equivalent, listing all ASCII character data received from the host
computer with their corresponding two–digit hexadecimal codes. Hex dumps are
used to troubleshoot printer data reception problems.
Printable characters print as the assigned symbol; nonprintable characters are
indicated by a period (.).
