Communication Issues

If there is a problem transferring data between the computer and the printer, put the printer in Communications Diagnostics mode (also referred to as DUMP mode). The printer prints ASCII characters and its text representation (or the period ‘.’, if not a printable character) from data received from the host computer.
  1. To enter Communications Diagnostics Mode:
  2. Print a configuration label as previously described.
    At the end of the diagnostics report, the printer prints “Press FEED key to enter DUMP mode”.
  3. Press
    FEED
    . The printer prints “Entering DUMP mode”.
    If
    FEED
     is not pressed within 3 seconds, the printer prints “DUMP mode not entered” and resumes normal operation.
The printer is in DUMP mode and prints the ASCII hex codes of any data sent to it and their text representation (or “.” if not a printable character).
A file with a .dmp extension containing the ASCII information is created and stored in the printer’s memory. It can be viewed, cloned, or deleted using the ZebraNet Bridge application. For more information on ZebraNet Bridge, go to zebra.com/zebranetbridge.
To terminate the Communications Diagnostics Mode and return the printer to normal operations:
  1. Turn the printer off.
  2. Wait 5 seconds.
  3. Turn the printer on.
