1.5.5 Preventing Hosts from Data Transfer Timeout

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

1.5.6 Interface Selection

The Stylus COLOR 800 can have three types of interfaces: parallel, serial, and optional Type-B. Each interface can be selected manually or automatically. Both modes are selected through default setting mode.

Manual Selection

One of 3 interfaces selected through the default setting mode. The selected interface is fixed.

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 receives 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 Selection and Interface State

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.
