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 print the Hex Dump Label:
To begin, go to the Diagnostics menu and enable Hex Dump Mode; see Section 4.5. 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, as
shown below. To exit Hex Dump Mode, re-enter the Diagnostics Menu and disable the Hex Dump
Mode, exit the menu, then save the changes.
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 Datamax-O’Neil Technical Support with any
questions.
