PREVENTION HOSTS FROM DATA TRANSFER TIME-OUT
When data is received from the parallel interface or the type B interface while no error
has occurred (including the pause condition), the printer receives data a rate of 2 byte/
second while buffer free space is less than 16 kbytes in order to prevent host timeout.
When buffer free space is more than 32kbytes, the 2 byte/second receive rate is cleared,
and receive is halted when free space reaches 16 bytes, and returns to the 2 byte/second
rate when free space reaches 512 kbyte or more.
INTERFACE SELECTION
The printer has the parallel interface, the USB interface, the optional interface. These
interfaces are selected manually by the default setting mode or selected automatically.
Manual selection
One of 3 interfaces can be selected; the parallel interface, the USB interface, the
optional interface.
Automatic selection
Select a interface which the printer received data first after power ON. If it passes
10 seconds after interruption of data receiving, it will be idle status (any interface
is not selected) and will select a interface which the printer received data first.
Interface state and interface selection
When the parallel interface is not selected, the interface goes into the busy
status.
Only reverse communication can be done at this time.
When the printer is initialized or returned to the idle state, the parallel
interface becomes ready status, the USB interface becomes non NACK reply
status, and the option interface resets OFF-LINE bit of Main Status Register
(MNSTS).
INIT signal on the parallel interface is not effective while that interface is not
selected or nibble Mode , ECP Mode.
