[1] Signal directions given relative to the printer.
[2] If active with no current print job, "WAITING FOR DATA" will be displayed. Specifying a quantity of 9999 while keeping this signal ON will cause non-stop label printing, except
in single label "Imaging Mode", which will cause the printer to stop between labels. See the Operator's Manual for details.

When inactive, outputs will be
pulled up to a voltage
determined by this jumper
setting, where:

Pins 1 – 2 = +5VDC;
JMP 1

Pins 2 – 3 = +24VDC; or,

None = an external voltage
(not to exceed +30VDC) via
external pull-ups providing a
20K ohm feedback path
through any two outputs.
Function / Description
Printer chassis is used.
Ground must be supplied.
Printer +5VDC is used (.5 amp maximum)
 Note: Drawing more than .5 amps can cause unreliable printer operation.
+5VDC must be supplied.

Media is advanced until the signal goes HIGH and, if not in continuous mode, the label
is positioned at the next available TOF.
The printer pauses when the signal is taken LOW.
The last label is reprinted exactly, with no increment or time stamp changes;
recommended for use during error conditions. Keeping this signal LOW produces non-
stop printing.
Printer +24 VDC (1.5 amp maximum).

Programmable . Signifies the End of Print (EOP) process.
Evoked during an Out of Stock condition. Active LOW.
Evoked during an Out of Ribbon condition. Active LOW.
Evoked when a label is waiting to print. After Start of Print is received, printing will begin.
For synchronization with the print cycle, End Of Print indicates the completion of the
process. Active LOW.
Evoked during a Linear Scanner or RFID fault condition. Active LOW.
