In DsExcel .NET, you can use the properties of the IPageSetup interface in order to configure paper settings for customized printing.

Configuring paper settings involves the following tasks:

1. Configure Paper Scaling
2. Configure Paper Size

Configure Paper Scaling

You can use the IsPercentScale property in order to control how to the spreadsheet is scaled; the FitToPagesTall property and the FitToPagesWide property in order to set its size; and the Zoom property in order to adjust the size of the paper that will be used for printing.

//Set paper scaling via percent scale 
            
worksheet.PageSetup.IsPercentScale = true;
worksheet.PageSetup.Zoom = 150;
            
//Set paper scaling via FitToPagesWide and FitToPagesTall    
            
worksheet.PageSetup.IsPercentScale = false;
worksheet.PageSetup.FitToPagesWide = 3;
worksheet.PageSetup.FitToPagesTall = 4;            
            

Configure Paper Size

You can use the PaperSize property in order to set the paper size for the paper that will be used for printing.

//Set built-in paper size. The Default is Letter
            
worksheet.PageSetup.PaperSize = PaperSize.A4;
