### Expected Behavior
using  webContents api to print an html file oriention  set to landscape in default printer settings and page size set to A5, 

mainWindow.webContents.print({ silent: true, printBackground: false, deviceName: 'HP LaserJet 1020' })

My issue is : it is not printing as defined in the default printer settings

but it currently printing is deviceName not set

and need to send mainWindow.webContents.print() api to silently and printer name 

### To Reproduce
If you provide a URL, please list the commands required to clone/setup/run your repo e.g.
```sh
$ git clone git@github.com:shabeer-mdy/electron-quick-start.git
$ npm install
$ npm start || electron .
```
and set any printer name to  mainWindow.webContents.print({ silent: true, printBackground: false, deviceName: 'HP LaserJet 1020' })

set any installed printer name
