4 Printer Fault Low Output Goes low when any printer fault is detected.

5 Ribbon Low Programmable Output

Goes high (or low) when a low ribbon supply

is detected.

6 End of Print Programmable Output

Goes high (or low) when printing is complete,

typically monitored to initiate the next Start of

Print sequence.

7 Backup Label Programmable Input

When received, will position a presented label

for printing, provided that the programmed

present distance is greater than zero.

Start of Print

I-Class and W-Class Sample SOP Circuit

Connections for an external Start of Print/Backup Label control can be made (1)

directly to Pin 8 / 7 using a TTL-level input or (2) with an interface circuit similar

to the one shown right. For additional interfacing requirements, see the table

above.
