Printing a Configuration Label

To print out a listing of the printer’s current configuration fol-

low these steps:

1. Turn the printer off.  Load the media compartment with 

journal media (media with no black bars printed on the 

back).

2. Press and hold the Feed Button.

3. Press and release the Power button and keep the Feed 

button pressed.  When printing starts, release the Feed 

button. 

Refer to Figure 26 for sample configuration printouts.

Communications Diagnostics

If there is a problem transferring data between the computer 

and the printer, try putting the printer in the Communications 

Diagnostics Mode (also referred to as the “DUMP” mode). The 

printer will print the ASCII characters and their text represen-

tation (or the period ‘.’, if not a printable character) for any data 

received from the host computer.

To enter Communications Diagnostics Mode:

1. Print a configuration label as described above. 

2. At the end of 2nd diagnostics report, the printer will print: 

“Press FEED key to enter DUMP mode”.

3. Press the FEED key. The printer will print: “Entering 

DUMP mode”.

4. At this point, the printer is in DUMP mode and will print 

the ASCII hex codes of any data sent to it, and their text 

representation (or “.” if not a printable character).

Additionally, a file with a “.dmp” extension containing the 

ASCII information will be created and stored in the printer’s 

memory. It can be viewed, “cloned” or deleted using the Label 

Vista application. (Refer the Label Vista documentation for 

more information.)
