epplus 打印功能

EPPlus库本身没有直接支持打印[功能](https://geek.csdn.net/educolumn/0cf712bbe06919ce80efc8d763fefd03?spm=1055.2569.3001.10083)，但你可以通过EPPlus库操作[excel文件](https://geek.csdn.net/educolumn/058a2f001dec80db1ef2d7bf8bc67c6b?spm=1055.2569.3001.10083)来实现打印[功能](https://geek.csdn.net/educolumn/0cf712bbe06919ce80efc8d763fefd03?spm=1055.2569.3001.10083)。下面是一些示例代码，演示如何使用EPPlus库来设置打印选项和打印[excel文件](https://geek.csdn.net/educolumn/058a2f001dec80db1ef2d7bf8bc67c6b?spm=1055.2569.3001.10083)： ```csharp using OfficeOpenXml; // 创建[excel文件](https://geek.csdn.net/educolumn/058a2f001dec80db1ef2d7bf8bc67c6b?spm=1055.2569.3001.10083) var file = new FileInfo("example.xlsx"); using (var package = new ExcelPackage(file)) // 获取工作表 var worksheet = package.Workbook.Worksheets.Add("Sheet1"); // 设置要打印的区域 worksheet.PrinterSettings.PrintArea = worksheet.Cells["A1:F10"]; // 设置打印方向为纵向 worksheet.PrinterSettings.Orientation = eOrientation.Portrait; // 设置页面边距 worksheet.PrinterSettings.LeftMargin = 0.5m; worksheet.PrinterSettings.RightMargin = 0.5m; worksheet.PrinterSettings.TopMargin = 0.5m; worksheet.PrinterSettings.BottomMargin = 0.5m; // 设置打印标题 ```
