In/Out Function Description

This signal (negative pulse) indicates that the
printer has received data and is ready to accept
next one.

This signal’s high level means that the print is
not ready to accept data.

This signal’s high level means that the printer is
in a state of paper-out error.

Always at high level when the printer is
powered on.

This signal’s low level means the printer is in a
state of error.

1.4.4 Interface Selection

The printer has 2 interfaces; the parallel interface and Type-B optional interface. These
interfaces are selected manually by Default Setting or selected automatically.

o

Manual Selection
One of 2 interfaces can be selected by Default Setting.

o

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 when it is powered on. Then the interface that receives data
first is selected. When the host stops data transfer and the printer is in stand-by
state for the 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 in busy state, the
selected interface is let as it is.

o

Interface State and Interface Selection
When the parallel interface is not selected, the interface gets into 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. Caution
that the interrupt signal such as a -INIT signal on the parallel interface is not
effective while that interface is not selected.

1.4.5 Prevention Hosts from Data Transfer Time-out

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

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

o

Off:
Communication is carried out in the conventional mode. A magic string (1284.4
synchronous commands) is discarded.

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 point­to-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 and blocking
of one has no effect on the others. The protocol operates over IEEE1284.
