Communication I/F Settings
This utility allows you to make printer communication settings. The port setting of the computer is not made,
so making the printer settings may cause a communication error with the printer. In such case, change the
printer driver settings or any other necessary settings on the computer so that they match with the settings
made on the printer.

Chapter 2 Using the Utility
USB
Configures the USB class.
• When using the UPOS select [Vender Class].
• When you do not need to use the [Printer Class], using [Vender Class] is recommended.
❏ Printer Class: Configures the printer to the printer class.
❏ Vender Class (Default Setting): Configures the printer to the vender class.
If you change the USB class from [Vender Class] to [Printer Class], the printer becomes a Printer Class
device. The computer detects the printer as a new Printer Class device and creates a new port.
Using the newly created port, you can print but cannot use the EPSON Status API. The existing port still allows
you to both print and use the EPSON Status API, so you can delete the newly created queue and use the
existing queue instead.
How to distinguish the EPSON Status API available port
Select [Properties]-[Ports] and check the “Port” and “Description”.

❏ IP Address:
Type a new IP address to be set to the printer.
Changing the printer IP address causes a communication error between the printer and the
computer. After the setting, change the setting of the printer driver and UPOS to the same as
that you made on the printer.
