详细说明：

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

本地打印：

//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" );

//"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;...)}..."

if( report == null || report.trim().length() == 0 ) throw new Exception( ServerMsg.getMessage(request,"jsp.dpArgError") );

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

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

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

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

String appmap = request.getContextPath();

String appRoot = ReportServlet.getUrlPrefix( request );

if( !appRoot.startsWith( "http" ) ){

String approot1 = request.getRequestURL().toString();

approot1 = approot1.substring( 0, approot1.indexOf( request.getRequestURI() ) );

appRoot = approot1 + appmap;

}

StringBuffer url = new StringBuffer( "printrpx://" );

url.append( "a=" + URLEncoder.encode( appRoot, "UTF-8" ) );

url.append( "&b=" + URLEncoder.encode( "/reportServlet;jsessionid=" + session.getId() + "?action=1", "UTF-8" ) );

url.append( "&c=" + URLEncoder.encode( report, "UTF-8" ) );

if( needSelectPrinter != null ) {

url.append( "&k=" + needSelectPrinter );

}

url.append( "&u=1" );

url.append( "&v=" + prompt );

url.append( "&x=UTF-8" );  //paramCharset

if( pages != null ) url.append( "&z=" + pages );

if( copies != null ) url.append( "&aa=" + copies );

url.append( "&ti=" + System.currentTimeMillis() );
