// Note: This function must be called in a separate thread.
// Because many functions in this module are blocking or synchronous.
// Calling this function from a thread that manages interaction with the user interface could make the application appear to be unresponsive.
// Steps:
// 1. Add the local port.
// 2. Check if the driver is installed.
// Uninstall the existing driver if it is installed.
// We should not check the driver version because the driver is deployed with the application.
// It's better to uninstall the existing driver and install the driver from the application.
// 3. Add the printer.
