print2flash的大体实现是这样的，通过把从客户端上传的word/Excel/ppt文件，调用print2flash官方提供的dll，转化成swf格式文件，最后浏览swf文件，就是上图中的效果。
具体使用 如下：
1、下载print2flash，这里是64位的，可以到官方http://print2flash.com/download.php下载最新的，其中的Print2Flash SDK 3.5，是java php .net asp的代码示例
2、配置服务信息，这一步很关键，不然会提示 COM 类工厂中 CLSID 为 {466FAC17-24D2-4B37-A2C4-E2CFA0D3E1E7} 的组件失败，原因是出现以下错误: 80040154 没有注册类 (异常来自 HRESULT:0x80040154 (REGDB_E_CLASSNOTREG))(不安装print2flash也会这样提示)
配置步骤：打开print2flash安装目录，64位操作系统默认在C:\Program Files (x86)\Print2Flash3下，右键管理员方式运行print2flash.exe，点击option—>Print2Flash Service Configuration,如下图：
