Revision B

1.2.6 Interface selection

The printer has 3 interfaces; the parallel interface, USB interface and Type-B optional interface. These interfaces are selected manually by Default Setting or selected automatically.

Manual selection

One of the three interfaces can be selected by Default Setting.

Automatic selection

The automatic interface selection is enabled by Default Setting. In this automatic interface selection mode, the printer is initialized to the idle state scanning which interface receives data at power-on. Then the interface that receives data first is selected. When the host stops data transfer and the printer is in the stand-by state for the period of seconds specified by Default Setting, the printer is returned to the idle state. As long as the host sends data or the printer interface is the busy state, the selected interface is let as it is.

Interface state and interface selection

When the parallel interface is not selected, the interface gets info a busy state. When the Type-B serial interface card is installed and it is not selected, the interface sends XOFF and sets the DTR signal MARK. When the optional interface is not selected, the printer sets “OFFLINE” bit of MNSTS register to the optional interface. When the printer is initialized or returned to the idle state, the parallel interface got into a ready state, the serial interface sends XON and sets the

DTR SPACE and the printer resets “OFFLINE” bit of MNSTS register to the optional interface. Note that the interrupt signal such as a -INIT signal on the parallel interface is not effective while that interface is not selected.

Preventing Hosts from Data Transfer Timeout

Generally, hosts abandons data transfer to peripherals when a peripheral is in the busy state for dozens of seconds continuously. To prevent hosts from this kind of timeout, the printer receives data very slowly, several bytes per minute, even if the printer is in the busy state. This slowdown is started when the rest of the input buffer becomes several thousands of bytes. At last, when the input buffer is full, the printer is in the busy state continuously.

IEEE1284.4 on the parallel interface and on the USB interface do not require this function.

Revision B

1.2.7 IEEE1284.4 protocol

The packet protocol described by IEEE1284.4 is supported on the parallel I/F.

Two function modes of IEEE1284.4 protocol, “Off” and “Auto”, are available and one of them is selected according to the value of Default setting. (See Section 1.3.5. Default Setting).

NOTE:Packet protocol option “Off” &“Auto” in Default setting mode are effective in not only parallel I/F but also USB I/F.

Auto: Communication is carried out in the convetional mode until a magic string (1284.4 synchronous commands) is received. By receiving a magic string, communication in IEEE1284.4 packet mode is started.

Off:	Communication is carried out in the convetional mode.

NOTE:The packet protocol of IEEE1284.4 allows a device to carry on multiple exchanges or conversations which contain data and/or control information with another device at the same time across a single point-to-point link. The protocol is not, however, a device control language. It does provide basic transport-level flow control and multiplexing services. The multiplexed logical channels are independent of each other and blocking of one has no effect on the others. The protocol operates over IEEE1284.
