General Purpose Input Output (GPIO) Port Applications
GPIO and Applicator Interface Card equipped printers can easily interface with most external controlling
devices. Function and setting preferences can be stored in non-volatile memory for subsequent power-ups
using the menu system of the printer, or via <STX>Kc commands.
Printing with GPIO: When the GPIO functions are enabled, the printer will not print a label until the
“Start of Print” signal goes active.
 Note: When a label is ready to print but awaiting a Start of Print signal, the prompting operation differs slightly
depending upon equipment:
• Non-Display Models – The STOP LED will flash.
• Display-Equipped Models – The display will indicate “WAITING FOR SIGNAL.”
CAUTION
Always wear a wrist strap and follow ESD prevention measures when handling the GPIO or
Applicator Interface Card. For specification information, reference the printer Maintenance Manual.
Functions vary according to printer model and card type, as discussed below.
M-Class GPIO
The connection to the GPIO signals can be accessed via the Option Port connector on the front of the
printer, or via the Main CCA:
