Printer Interface (GPIO) Specifications
The Printer Electrical Signal Interface and Protocol is developed to coordinate the
printing of labels with an external process in a production workflow. Using this protocol,
the printer (Device A) receives a print job but will not print until it receives a signal from
an external device (Device B).
The following scenario illustrates how this could be used:
1. A box on a conveyor arrives at a workstation. A barcode is read and triggers a
message to a computer.
2. The computer sends a print job (probably with some variable data) to the printer.
3. The box reaches the next station on the conveyor and triggers a signal (e.g. by a
footswitch or automatically by a sensor). The printer starts printing when the signal
is received.
The electrical signal to initiate printing is received at the printer’s GPIO port. The
handshaking protocol is as follows:
• The printer signals it is ready to print by pulling up the Print Job Ready signal from
low to high.
• Device B signals it is ready by pulling up the Ready signal. This must remain high for
at least 50 ms before returning to low.
• The printer prints and pulls down the signal when printing is completed.
