Set Auxiliary Port

Description The ^JJ command allows you to control an online verifier or applicator
device.

Format ^JJa,b,c,d,e,f

This table identifies the parameters for this format:

Parameters Details
a = operational mode Accepted Values:
for auxiliary port 0 = off
1 = reprint on error—the printer stops on a label with a
verification error. When PAUSE is pressed, the label
reprints (if ^JZ is set to reprint). If a bar code is near
the upper edge of a label, the label feeds out far enough
for the bar code to be verified and then backfeeds to
allow the next label to be printed and verified.
2 = maximum throughput—the printer stops when a
verification error is detected. 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 stop
immediately on a label with a verification error.
Default Value: 0
b = application mode Accepted Values:
0 = off
1 = End Print signal normally high, and low only when the
printer is moving the label forward.
2 = End Print signal normally low, and high only when the
printer is moving the label forward.
3 = End Print signal normally high, and low for 20 ms when
a label has been printed and positioned.
4 = End Print signal normally low, and high for 20 ms when
a label has been printed and positioned.
Default Value: 0
c = application mode Accepted Values:
start signal print p = Pulse Mode – Start Print signal must be de-asserted
before it can be asserted for the next label.
l = Level Mode – Start Print signal does not need to be de-
asserted to print the next label. As long as the Start Print
signal is low and a label is formatted, a label prints.
Default Value: 0
