3.4 Hex Dump Mode

Hex Dump Mode is a diagnostic tool for isolating communications and DPL syntax errors,
by allowing input (host) data to output (printer) data comparisons. All data received by the
printer will be output in hexadecimal code along with the printable ASCII equivalents, as
shown below. To identify possible handshaking problems, repeatedly send the format and
sections of missing data can become apparent. To debug DPL label formats reference the
Class Series 2 Programmer's Manual.
After sending a label format to the printer, the output will be immediate and in the form
shown below. 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.
