First of all I would recommend to reconsider your approach as testing browser print dialog is not something you should be normally doint

If you still decide to go to that direction be aware that the "Cancel" button is hidden in Shadow DOM so you will need to identify all ShadowRoot elements, cast them to IWebElement, locate the "interesting" child, repeat

Example code:

driver.SwitchTo().Window(driver.WindowHandles[1]);
IWebElement printPreviewApp = driver.FindElement(By.TagName("print-preview-app"));
IWebElement printPreviewAppConten = expandShadowRoot(printPreviewApp, driver);
IWebElement printPreviewSidebar = printPreviewAppConten.FindElement(By.TagName("print-preview-sidebar"));
IWebElement printPreviewSidebarContent = expandShadowRoot(printPreviewSidebar, driver);
IWebElement printPreviewHeader = printPreviewSidebarContent.FindElement(By.TagName("print-preview-header"));
IWebElement printPreviewHeaderContent = expandShadowRoot(printPreviewHeader,driver);
printPreviewHeaderContent.FindElements(By.TagName("paper-button"))[1].Click();

The associated expandShadowRoot function:

private IWebElement expandShadowRoot(IWebElement parent, IWebDriver driver) {
    return (IWebElement) ((IJavaScriptExecutor )driver).ExecuteScript("return arguments[0].shadowRoot", parent);
}

Thanks a lot , found this approach after working whole day going through various libraries . — Anurag, May 29 '21 at 12:25
