当用户需要打印两个控件的图纸时，可以采用嵌套打印实现。点击此处在线演示。
实现嵌套打印功能，首先将两个控件放入网页中，js代码如下：

首先通过id得到两个控件，新建一个COM组件对象，设置打印的位置等常规设置，具体实现js代码如下：

function
BatchPrintDialog() {
var
ocx1 = document.getElementById(
"MxDrawXCtrl1"
);
var
ocx2 = document.getElementById(
"MxDrawXCtrl2"
);
var
print = ocx1.NewComObject(
"IMxDrawPrint"
);
// 开始打印.
print.BeginNestedPrint();
//iFlag = 0表示页边距，iFlag = 1表示打印区域矩形框位置
print.Flag = 1;
// 打印区位置(10,10,200,100),坐标系统是，X从左到右，Y从上到下.
//打印的页边距的左边距离
print.dLeftPageMargin = 10;
//打印的页边距的上边距离
print.dTopPageMargin = 10;
//打印的页边距的右边距离
print.dRightPageMargin = 200;
//打印的页边距的下边距离
print.dBottomPageMargin = 100;
// 把屏幕显示内容进行的打印,打印第一个控件。
ocx1.MakeCurrentOcx();
print.PrintScreen();
ocx2.MakeCurrentOcx();
// 打印区位置(10,110,200,210),坐标系统是，X从左到右，Y从上到下.
//打印的页边距的上边距离
print.dTopPageMargin = 110;
//打印的页边距的下边距离
print.dBottomPageMargin = 210;
// 把屏幕显示内容进行的打印,打印第二个控件。
print.PrintScreen();
//结束嵌套打印
print.EndNestedPrint();
}
