6.2 Hex Dump Mode
The Hex Dump Mode is a useful tool for diagnosing problems, including
communication and DPL syntax errors, allowing a comparison of input strings
(sent by host) to output data (received by printer). To decode this information,
the Programmer’s Manual is an essential reference. This output can be used for
debugging the label format. In addition, by repeatedly sending a format, this
mode can uncover handshaking problems (if they exist). Handshaking problems
are identified by sections of missing data in the character string.
To begin, go to the Diagnostics menu and enable Hex Dump Mode; see Section
4.1.7. Exit the menu and save the changes. Now, ‘HEX DUMP MODE’ will be
indicated by the display and all data sent to the printer will now be output in
hexadecimal code, along with the printable ASCII equivalents.
The figure below is a sample Hex Dump Label. After sending a label format to
the printer, the hex code output will be immediate. As a final note, many
software programs use bit mapping to construct the label, making diagnosis
difficult. Contact Technical Support with any questions.
þ Note: To return to Ready Mode, re-enter the Diagnostics Menu and disable
the Hex Dump Mode, exit the menu, then save the changes.
