Hex Code Printout
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 (.). To make a hex printout:
1. Press ON LINE to place the printer off–line. “Off–line/Emulation”
displays.
2. Raise the printer cover.
3. Simultaneously press the UP and DOWN switches to unlock the
ENTER switch. “Unlocked” displays briefly. (If “Locked” displays,
simply press UP and DOWN again.)
4. Press DOWN. “Emulation/LG06” displays.
5. Press NEXT until “Emulation/Hex Dump” displays.
6. Press ENTER. This selects the hex dump emulation and an asterisk (*)
appears after the display message. (“Emulation/Hex Dump * ” displays.)
7. Press ON LINE. The display indicates that the printer is on–line in hex
dump mode (“On–Line/Hex Dump”).
8. Send the data from the host — the data print in hex dump format. (Any
data remaining in the buffer print before the hex code printout starts.)
9. Press ON LINE again to stop the hex dump. The display reads
“Off–line/Emulation”.
10. Press DOWN. “Emulation/Hex dump * ” displays. Press NEXT until
the desired emulation appears. (For example: “Emulation/LG06”)
11. Press ENTER to select the desired emulation. An asterisk (*) appears
after the display message. (For example: “Emulation/LG06 * ”)
12. Simultaneously press the UP and DOWN switches to lock the ENTER
switch. “Locked” displays briefly.
13. Close the printer cover.
14. Press ON LINE to place the printer on–line.
