￿Sending BDC-ST through DBIN register

When State-Reply is set “ON” by ST from Type-B I/F, sending BDC-ST through DBIN register is started. When State-Reply is started, “Start” and “End” of BDC-ST characters are announced by sending the Main command 0Eh.

1.4.4 Prevention Hosts from Data Transfer Time-out

Generally, hosts abandon data transfer to peripherals when a peripheral is BUSY continuously for dozens of seconds. To prevent this kind of time-out, the printer receives data very slowly, several bytes par minute, even the printer is in a busy state. This slowdown starts when the remainder of input buffer drops under several hundreds of bytes. Finally, the printer is BUSY continuously when the input buffer is full.

1.4.5 Interface Selection

The EPSON Stylus COLOR 3000 has three types of interfaces: Parallel, Serial, and optional Type-B. Each interface can be selected manually or automatically. Both modes are selected thorough the default setting mode.

￿Manual selection

The interface selected through the default setting mode always prints out data from the host.

￿Automatic selection

Automatic interface selection is enabled in default setting mode. In automatic interface selection mode, the printer is initialized to the idle state when it is powered on (*1) scanning which interface is to receive data. Then the interface that received data first is selected. When the host stops data transfer and the printer is in the standby state for a number of seconds, the printer returns to the idle state. As long as the host sends data or the printer interface is busy state, the selected interface is left as it is.

*1 No interface is selected in this state.

￿Interface State and Interface Selection

￿When an interface other than the parallel interface is selected, the parallel interface goes into the BUSY state.

￿When the interface other than serial interface is selected, the serial interface sets the DTR signal MARK.

￿When the printer is initialized and returned to idle state, the parallel interface goes into ready state and the serial interface sets the DTR signal SPACE.

Note) An interrupt signal such as the INIT on the parallel interface is ignored while that interface is not selected.
