AR-PB2A
Setting
Automatic Between When receiving data is detected through
Switching Jobs a port, sensing data receipt from each
port, considers the port as current (port
automatic sensing processing), and
processes the data received only through
the current port. Then until the job ends
in the situation described below in 1) or
2), the data through the current port is
only processed. After the print job ends,
the port automatic sensing processing
restarts.
1) The print job is completed by the
job-end command.
2) The current port gets into the state of
waiting for data receipt, and after no
data is received for a certain time (I/O
time-out value), print job ends by the
I/O time-out.
After I/O When receiving data is detected through
Time-out a port, sensing data receipt from each
port, considers the port as current (port
automatic sensing processing) and
processes the data received only through
the current port. Then until the I/O
time-out in the situation described below
in 1), the data through the current port is
only processed. After the I/O time-out,
the port automatic sensing processing
restarts.
1) The current port gets into the state of
waiting for data receipt, and after no
data is received for a certain time (I/O
time-out value), the print job ends by
the I/O time-out. (When the print job
has not been completed , it ends
simultaneously.
Fixed Disables Receives data only through the Network
P1284 Port (NIC) port.

Note: In the I/O time-out, the count starts at the point that data is not
acquired via the receiving buffer. When receiving the data until
the I/O time-out, the count is reset to stop.
In the between jobs setting of the automatic switching, the
conditions that a print job will be completed are as follows.
