Changing the Protocol

When you first turn the printer on, the active protocol depends on what port will be used for printing.

For Macro 1: If you use the serial port, the active protocol will be the DEC protocol.

If you use the parallel port, the active protocol will be the Epson protocol.

For Macro 2: If you use the serial port, the active protocol will be the DEC protocol. If you use the parallel port, the active protocol will be the IBM protocol.

This printer has three protocols and allows you to set the protocol mode in one of the following three ways: the printer engages one of the three protocols, automatically determines the active protocol, or assigns different protocols for parallel and serial interfaces.

To change the protocol:

1.Make sure the printer is in the Ready state (no data to be printed).

2.Repeatedly press the Protocol button 1. The DEC and PPX24 indicators turn on and off. The combination of lighted indicators shows the protocol mode selected, according to the next table.
