6-3. Print Interface (Option 01 : Centronics Parallel Interface)
This Print Interface Option is based on “Centronics Parallel Interface”, so this print interface can be
connected other printers using this communication method.
But, the print format is programmed based on our “SE7300”, and “SE7320” Industrial Printers, so you
had better to use these printer for convenience.
