Printing a Conguration Label
To print out a listing of the printer’s current conguration, follow
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.
Note • The conguration report can also be pressing the
Conguration button and navigating to SETTINGS>PRINT.
Refer to “Figure 21 • Conguration Label” on page 50 for sample
conguration 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 representation
(or the period ‘.’, if not a printable character) for any data received
from the host computer.
To enter Communications Diagnostics Mode:
1. Print a conguration label as described above.
2. At the end of the 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”.
Note • If the FEED key is not pressed within 3 seconds, the printer
will print “DUMP mode not entered” and will resume normal
operation.
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).
