Set Auxiliary Port
The ^JJ (Set Auxiliary Port) command allows you to control an on-
line verifier or applicator device via ZPL.
The format for the ^JJ instruction is:
^JJo,a
where
^JJ = Set Auxiliary Port
o = Operational Modes for the Aux Port.
Factory Default: 0 Off - The auxiliary port output signal is
not provided for the verifier.
Initial Value at Power-up: The last value saved.
Other Values:
1. Reprint on Error - The printer stops on a label with a
verification error. When the pause key is pressed, this label
is then reprinted (if Reprint on Error, ^JZ, is set to reprint)
. If a bar code is near the upper edge of a label, the label
will feed out far enough for the bar code to be verified and
then backfeed to allow the next label to be printed and veri-
fied.
2. Maximum Throughput - The printer stops when a veri-
fication error is detected. In this mode, the printer starts
printing the next label while the verifier is still checking the
previous label. This mode provides maximum throughput,
but does not allow the printer to immediately stop on a
label with a verification error.
NOTE: When set to Maximum throughput via this com-
mand, the ^JZ (Reprint on Error) command has no affect
- ^JJ overrides it so that the label will not be reprinted
after an error.
