Hex Code Printout
Hex dumps list all ASCII character data received from the host computer
with their corresponding two–digit hexadecimal codes. (The ASCII character
set is on page 4–31.) 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.

1. On the control panel, press the ON LINE switch to place the printer
off–line. “Off–line Emulation” displays.

dump mode: “On–Line Hex Dump”
