Auto Interface Select
The setup feature Interface Select controls the operation of interface arbitration. One of 3 settings is possible:
Parallel Only: With this setting the serial interface is ignored.
Serial Only: With this setting the parallel interface is ignored.
Auto Select: With this setting, the printer automatically arbitrates between the parallel and serial interfaces. The first interface to go active maintains active status while the other interface is held busy. After a time out period, the other interface is placed in a ready state.
