Roles of Port1 to Port3

In the socket server function of TCP/IP, either of the following connection methods can be used.

The ports to be used and their roles change depending on the connection method and communication protocol.

Two-port connection

•	If AEP mode is disabled (initial value)

Port1 is used for receiving print data, and Port2 is used for returning the product status.

Two-port connection is available when the communication protocol is STATUS4.

•	If AEP mode is enabled

Port1 and Port3 can be used for both receiving print data and returning the product status. Port2 cannot be used.

One-port connection

One port is used for both receiving print data and returning the product status.

When the communication protocol is STATUS4, Port3 is used.

When the communication protocol is STATUS3 or STATUS5, Port1 or Port3 is used.

• AEP does not support STATUS3, STATUS4, or STATUS5.

The setting items are as follows:

[Port1]

Set the port number for Port1.

If AEP mode is disabled, and while in the two-port connection of STATUS4, this port is used for receiving print data. While in the one-port connection of STATUS3/STATUS5, this port is used for both receiving print data and returning the product status.

While in the two-port connection in AEP mode, this port can be used for both receiving print data and returning the product status.

The setting range is from 1 to 65535.

• Set different values for each port (1, 2, and 3). • Set a port number not used by other services. If port numbers that overlap with those used by other services are used, communication cannot be performed properly.

• AEP does not support STATUS3, STATUS4, or STATUS5.

[Port2]

Set the port number for Port2.

While in the two-port connection of STATUS4, this port is used for returning the product status.

The setting range is from 1 to 65535.

• Set different values for each port (1, 2, and 3). • Set a port number not used by other services. If port numbers that overlap with those used by other services are used, communication cannot be performed properly.

• The setting is disabled if [AEP] is enabled.

[Port3]

Set the port number for Port3.

If AEP mode is disabled, and while in the one-port connection of STATUS3/STATUS4/STATUS5, this port is used for both receiving print data and returning the product status.

While in the two-port connection in AEP mode, this port can be used for both receiving print data and returning the product status.

The setting range is from 1 to 65535.

• Set different values for each port (1, 2, and 3). • Set a port number not used by other services. If port numbers that overlap with those used by other services are used, communication cannot be performed properly.

• You can change the return status format of Port3 to compatible mode by enabling [Legacy Status for Port 9100]. • AEP does not support STATUS3, STATUS4, or STATUS5.

[Flow Control]

Set the communication protocol.

The options are as follows:

•

[STATUS4]

•	[STATUS4 ENQ]

•

[STATUS3]

•

[STATUS5]

•

[NONE]

[TCP Connection Queue]

Set whether to allow queuing for connection when multiple hosts or applications are sending connection requests to the product.

While connecting with one host or application, the product can receive connection requests from other hosts or applications. The subsequent connection requests are put on hold, and processed in order of reception after the first connection is closed.

While connecting with one host or application, the product cannot receive connection requests from other hosts or applications.

• When you have enabled the setting, be sure to use one port connection for STATUS3, STATUS4, and STATUS5. Operation using two port connections for STATUS4 is not guaranteed.

[Legacy Status for Port 9100]

Set whether to change the return status format of Port3 to compatible mode.

Does not appear if you have selected [NONE] in the [Flow Control] menu.

In compatible mode, the return status format of Port3 becomes as follows:

STATUS3

(Standard mode)

STATUS4

(Compatible mode)

(Standard mode)

(Compatible mode)

(Standard mode)
