Printing A Hex Dump
Figure 23. Hex Dump Sample
A hex code printout (or hex dump) is a translation of all host interface data to
its hexadecimal or symbolic 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 (.).
See Appendix C for hex-to-ASCII conversion. Table 23 shows the procedure
for printing a hex dump.
