At times, you may want to print only a specific area in a worksheet instead of printing the whole worksheet.
GcExcel .NET supports customized printing by allowing users to select a range of cells in order to configure the desired print area in a worksheet. This can be done by using the PrintArea property of the IPageSetup interface.
//Set print area in the worksheet
worksheet.PageSetup.PrintArea = "$D$5:$G$10";
