`webContents.print()` shold send print job to a printer

### Actual behavior
Nothing happens. Callback doesn't gets called. 

`printToPDF` works though.

```
let deviceName = 'HP LaserJet 1020'
let options = {deviceName, silent: true}
win.webContents.print({}, (err) => {
    if (!err)
      console.error('printing failed')
})
```
