TM-T20II Software Installer
❏ Printer Class: Configures the printer to the printer class.
❏ Vender Class: 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.
