Auto Switching
Gives the printer the ability to handle multiple data streams
simultaneously. With Auto Switching, the printer can service hosts
attached to the serial and parallel ports as if they were the only
interface connected.
simultaneously. With Auto Switching, the printer can service hosts
attached to the serial and parallel ports as if they were the only
interface connected.
For example, if the host computer sends one print job to the RS-
232 serial port and a separate print job to the IEEE 1284 parallel
port, the printer’s Auto Switching is able to handle both jobs, in the
order they were received, without the user having to reconfigure the
selected interface between jobs. The hotports are Parallel and
Serial.

Port Type
Select the types of parallel and serial interfaces which are
connected to the printer. For example, if your printer is attached to
one host with a Centronics connection and a second host with an
RS-422 serial connection, you would select Centronics under the
Parallel Hotport menu, RS-422 under the Serial Hotport menu.

one host with a Centronics connection and a second host with an
RS-422 serial connection, you would select Centronics under the
Parallel Hotport menu, RS-422 under the Serial Hotport menu.
Trickle Time
When the printer is printing data from a host and a second job is
received by the printer from a different host, Trickle Time prevents
the second host from timing out while it is waiting for its data to be
printed. In order to support this feature, the port has to be able to
accept data from the host and store it for future use.

accept data from the host and store it for future use.
For example, if the printer is printing a job from the serial port, and
then receives a second print job from the parallel port, the data from
the parallel port will “trickle” bit by bit into the printer buffer to
prevent a timeout error from being sent back to the host connected
to the parallel port.

prevent a timeout error from being sent back to the host connected
to the parallel port.
The selected value is the time that the printer waits before getting
the next byte of data from the host. The Trickle Time value should
be less than the host time out value, but not too much shorter or
else the printer fills up its buffer too fast.
