StarIODeviceSetting SDK for Universal Windows Platform C#

For more information about the API, supported OS, development environment, and supported printers, please refer to the manual.

Reference

SteadyLAN function is not available from the UWP application even if you set it to SteadyLAN for Windows because UWP application cannot communicate with the Star Printer via USB I/F. This function is available for Windows Desktop applications when you set to SteadyLAN for Windows.
SteadyLAN function must be configured to match the operating system (OS) of the device. It cannot be used with an OS different from the printer's settings. For more information, please refer to the manual.
