Answer 1

You need media query for switching between print and screen option

@media screen { /* for screen option*/

p {

      font-family: verdana, sans-serif;

      font-size: 17px;

  }

   }

@media print { /* for print option*/

 p {

     font-family: georgia, serif;
     font-size: 14px;
     color: blue;
   }

  }
