To handle devices with POS for.NET, you need a software component called a service object.
It needs to be made according to the interface specification of POS for.NET or OPOS.
Please refer to this site. POS for .NET Architecture (POS for .NET v1.14 SDK Documentation)
Service objects are usually provided by the hardware vendor.
On sites that are considered printer vendors, such software does not appear to be available.
This will not work with POSfor.NET. BC95AC Thermal Receipt Printer
If you want to print from POS for.NET, switch to the printer of the vendor that provides the service object.
If you want to use this printer, please send the ESC/POS control code directly using the serial port.
Alternatively, you may try using the Windows.Devices.PointOfService interface with the LAN connection option.
However, I don't know if this method will succeed.

PosPrinter Class
Receipt Printer (POSPrinter) - Supported Point of Service Peripherals
Connectivity Support
Network and Bluetooth Windows supports network and Bluetooth connected receipt printers using the Epson ESC/POS printer control language.
The printers listed below are discovered automatically using POSPrinter APIs.
Additional receipt printers which provide an ESC/POS emulation may also work but would need to be associated using an out of band pairing process.
Note: slip station and journal stations are not supported through this method.
