Crystal Report打印功能在部署后无法使用？

Question

我使用水晶报表来构建报表，开发时一切正常。
但是在部署网站后，打印功能不起作用。

我使用_rptDocument.PrintToPrinter（1，false，0，0）;打印报告。

我已经尝试了两种方法来部署网站

1. 正常发布选项。
2. Web部署项目。

但我得到了相同的输出，打印功能不起作用。
另外，我试图设置默认打印机，这也不起作用。

任何想法？

Answer 1

在Web服务器上打印并不是一个好主意。应该发生什么？用户在您的服务器打印机上打印？使用CR来创建PDF。将它们流到您的客户端。他们可以使用本地打印机。

试试这个： - 创建PDF和打开的浏览器选项... enter code here

string fname = "Report" + ".pdf";`enter code here` 
     //Create instance for crystal report Export option class 
     ExportOptions exprtopt = default(ExportOptions); 

     //create instance for destination option - This one is used to set path of your pdf file save 
     DiskFileDestinationOptions destiopt = new DiskFileDestinationOptions(); 

     //Bind data in the crystal report first before export cystal report to PDF 
     ReportDocument RptDoc = new ReportDocument(); 

     //Map your crystal report path 
     // RD.Load(Server.MapPath("~/CrystalReport2.rpt")); 

     //Set your crystal report datasource as dt 


     //Get path and assign into destination DiskFileName 
     destiopt.DiskFileName = Server.MapPath(fname); 

     exprtopt = RD.ExportOptions; 
     exprtopt.ExportDestinationType = ExportDestinationType.DiskFile; 

     //use PortableDocFormat for PDF data 
     exprtopt.ExportFormatType = ExportFormatType.PortableDocFormat; 
     exprtopt.DestinationOptions = destiopt; 

     //finally export your report document 
     RD.Export(); 

     //To open your PDF after save it from crystal report 

     string Path = Server.MapPath(fname); 

     //create instance to client to open your pdf 
     WebClient client = new WebClient(); 

     //Assign path to download pdf 
     Byte[] buffer = client.DownloadData(Path); 

     //metion content type as PDF and write 
     // Response.ContentType = "application/pdf"; 
     //Response.AddHeader("content-length", buffer.Length.ToString()); 
     //Response.BinaryWrite(buffer); 

     //====================================== 
     Response.Write("<script>"); 
     Response.Write("window.open('" + fname + "', '_newtab');"); 
     Response.Write("</script>"); 
     //===================================
