问题描述

如何将客户端的打印机上打印从CrystalReport（ASP.NET）报告。

How do I print report from CrystalReport (ASP.NET) on a client side printer.

推荐答案

您有两种选择：

1. 设置的打印模式，以ActiveX或PDF，并保留Crystal报表查看器工具栏来处理它。


2. 创建在iframe的PDF，并用JavaScript触发打印命令。

要简化用户必须安装在每个客户端我的隐藏PDF选项和一个单独的按钮继续打印到客户端的内容。

To simplify what the users had to install on each client I went with the hidden pdf option and a separate button to print to client.

在aspx页面我有一个asp的文字，我与1px的PDF格式嵌入式对象x 1像素的填充，所以它不是对用户可见。然后在页面加载调用printToPrinter方法​​。

On the aspx page I have an asp literal that I populate with the pdf embeded object at 1px x 1px so it isn't visible to the user. Then on pageload call the printToPrinter method.

// On server side
// Export to PDF
Guid imageGuid = Guid.NewGuid();
string _pdfName = String.Format(@"{0}{1}{2}.pdf", _pdfPath, _reportName, imageGuid);
// expport to unique filename
// ...
// Display the pdf object 
_sb.AppendFormat("<object ID=\"pdfObject\" type=\"application/pdf\" data=\"{0}\" src=\"{0}\" style=\"width: {1}; height: {2}; ", _pdf2Name, _width, _height);
_sb.AppendLine("z-index:1; display: block; border: 1px solid #cccccc; top: 0; left: 0; position: absolute;-+ \">");
_sb.Append("</object>");
pdfLiteral.Text = _sb.ToString();
pdfLiteral.Visible = true;

// javascript
// on document load call the printWithDialog function
 var code = function(){
 try
     {
        var pdf = $get('pdfObject');
        if (pdf == null)
            return;
        try {
            pdf.printWithDialog();
        }
        catch (err) {
            alert('Please Install Adobe Acrobat reader to use this feature');
        } 
     }
     catch(err)
     {
     }
  };
window.setTimeout(code, 1000);
