Printing a Hex Dump
A hex code printout (or hex dump) is basically a translation of all host
interface data to its hexadecimal equivalent. A hex dump lists 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 (.); and paper instructions (PI) are indicated by a “p”.
Table 18 shows the procedure for printing a hex dump.
