Y-type Connection
A Y-type connection allows you to connect to the customer display via a TM printer from the computer’s serial
port.
The data flow when the Y-type connection is as follows.
• The data from the computer is transmitted to the TM printer and the same data is transmitted to the cus-
tomer display with the Y-type connection.
• The Select peripheral device(s) command of ESC/POS distinguishes between the data for the customer dis-
play and the data for the TM printer.
