- Electron version: 0.37.2
- Operating system: Windows 7 64-bit

I have tried to call `mainWindow.webContents.print`, which showed the printer dialog but when I choose the printer, it just does nothing. Not even an error.

I have tried with multiple printers such as physical and virtual one (like print to XPS/PDF).

I suspect its my code, so I tried this [this example](https://github.com/hokein/electron-sample-apps/tree/master/printing) as well but I got same result.

After that I tested it on another computer (Microsoft surface 4) and still nothing.

Then  I run the same code on Mac OS, and it was working ok.

So I'm confusing right now and wondering if anybody else have same issue or not...

PS: `webContents.printToPDF` was also okay on windows since I guess has nothing to do with OS printing functionality.
