批量直接打印

客户端经常需要对报表进行批量打印，此时可以调用applet打印或者PDF打印进行批量打印操作，用法如下：

applet打印：

<%

//此JSP参数格式为：report={无参数报表名}{报表1(参数1=value1;参数2=value2;...)}{报表2(参数1=value1;参数2=value2;...)}...&prompt=yes&needSelectPrinter=yes

request.setCharacterEncoding( "UTF-8" );

String report = request.getParameter( "report" );

if( report == null || report.trim().length() == 0 ) throw new Exception( "请输入报表文件名及参数串report={无参数报表名}{报表1(参数1=value1;参数2=value2;...)}{报表2(参数1=value1;参数2=value2;...)}..." );

String prompt = request.getParameter( "prompt" );

String needSelectPrinter = request.getParameter( "needSelectPrinter" );

String pages = request.getParameter( "pages" );

String copies = request.getParameter( "copies" );

if( pages == null ) pages = "";

if( copies == null ) copies = "1";

String appmap = request.getContextPath();

String serverPort = String.valueOf( request.getServerPort() );

String serverName = request.getServerName();

String appRoot = "http://" + serverName + ":" + serverPort + appmap;

%>

打印其它相关知识:

1.  批量打印时，可以在第一张报表打印前弹出一个页面设置窗口，用户输入新的页面设置数据后，所有的报表都可以使用此设置进行打印

 方法：在directprint.jsp中增加下面的参数

 <param name="needSetPageSize" value="yes">

2.  批量打印时，也可以使用以前保存的客户端打印设置，在directprint.jsp中增加下面的参数

 <param name="savePrintSetup" value="yes">

3.  html报表、打印方式发布的报表、批量打印报表在打印完成后，均可以回调页面中的一个js函数，以便让用户可以实现打印后的处理事件.用户在页面中写一个名称为raqsoft_printOver()的javaScript函数，通过此函数实现打印后的处理

 

PDF打印：

<script language=javascript>

var myToast;

function showToast() {

myToast = $().toastmessage('showToast', {

text  : '<%=ServerMsg.getMessage(request,"jsp.loadingPrint")%>',

sticky  : true,

position : 'middle-center',

type:  'notice'

});

  }

function closeToast() {

$().toastmessage('removeToast', myToast);

}

</script>

//此JSP参数格式为：report={无参数报表名}{报表1(参数1=value1;参数2=value2;...)}{报表2(参数1=value1;参数2=value2;...)}

request.setCharacterEncoding( "UTF-8" );

String report = request.getParameter( "report" );

if( report == null || report.trim().length() == 0 ) throw new Exception( "请输入报表文件名及参数串report={无参数报表名}{报表1(参数1=value1;参数2=value2;...)}{报表2(参数1=value1;参数2=value2;...)}..." );

String src = request.getContextPath() + ServletMappings.getMapping( "com.raqsoft.report.view.ReportServlet" ) + "?action=45&report=" + URLEncoder.encode( report, "UTF-8" );

String preview = request.getParameter( "preview" );

if( "no".equalsIgnoreCase( preview ) ) {

String url = appmap + ReportConfig.raqsoftDir + "/pdfjs/pdfDirectPrint.jsp?src=" + URLEncoder.encode( src, "UTF-8" );

%>

  <iframe src="<%=url%>" style="position:absolute;left:-100px;top:-100px" width=50 height=50></iframe>

<script language=javascript>

showToast();

</script>

PDF批量打印可访问pdfBatchPrint.jsp，示例url如：http://localhost:6868/demo/reportJsp/pdfBatchPrint.jsp?report={a.rpx}{b.rpx(bid=10248;eid=10250)}&preview=yes

当参数preview的值为no时，则为直接批量打印；无此参数或参数值不为no时，则为预览后批量打印。
