Setting Printer from Selenium UI-Test

[pschwarzer-tt]

Hi,

we are currently implementing Selenium UI-Tests for a WebView2 based application. The application runs as an executable and the Selenium-Tests are connected by --remote-debugging-port, which works fine. But one issue we still facing, how we can print with Selenium using the "Save as PDF" option by default?

In the WebView2 application we set the default download folder path with:

if (SUCCEEDED(webView2_13->get_Profile(&profile)))
{
   if (FAILED(profile->put_DefaultDownloadFolderPath(m_PdfOutFolder.c_str())))
   {
       LOG_WARNING("Failed to set default PDF download folder.");
   }
}

and we run the WebView2 application with additional browser arguments --kiosk-mode. Within the application we have a button, that triggers window.print().

For us it looks like, the default printer seems to be "Microsoft Print to PDF", but this option ignores the value of put_DefaultDownloadFolderPath. "Save as PDF" handles filename and location propably.

So how we can ensure, that printer "Save as PDF" is selected, when we start our Selenium Tests?

Or is there any possibility to set the default print settings on webview startup, compareable in setting the DefaultDownloadFolderPath, which allows me to set the "Save as PDF" option?
