In DsExcel Java, you can use the methods 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 getIsPercentScale method in order to control how to the spreadsheet is scaled; the setIsPercentScale method, the setZoom method and the getPageSetup method in order to adjust the size of the paper that will be used for printing.

// Set paper scaling via percent scale
worksheet.getPageSetup().setIsPercentScale(true);
        
// Set paper scaling via zoom
worksheet.getPageSetup().setZoom(150);
        
// Set paper scaling via Fit to page's wide & tall
worksheet.getPageSetup().setIsPercentScale(false);
worksheet.getPageSetup().setFitToPagesWide(3);
worksheet.getPageSetup().setFitToPagesTall(4);

Configure Paper Size

You can use the getPageSetup method and setPaperSize method in order to set the paper size for the paper that will be used for printing.

// Set built-in paper size. Default is Letter Format - A4
worksheet.getPageSetup().setPaperSize(PaperSize.A4);
