Install Printers with batch file

Dear Coleagues,
I use to place the following batch file(start \\printservername\printersharename) for my users to enable install any network printer they may choose. But running this kid of batch file brings a prompt where you have to select yes before the printer is installed. I was wonering if there's a switch I could incorporate into this batch file to automatically answer yes to the prompt and for the batch file to run in silent mode.

Thanks
