Reporting web portal -Convert a report page into pdf download(ASP.NET Razor c#)

We have already developed Asp.net Razor c# program to generate reports for Power Monitoring System. Reports are able to generate and we are able to print pdf. But the windows print option is not fit into one screen (Piechart not fully visible, bar chart alignment issue). So we would like to provide pdf download option. So that it will have pdf with proper alignment and fit properly on the page what ever necessary to be there.

Logics are not required to change. Only the pdf download option has to provide and align the print pdf option.
