<h2><font color="#009999">超多页打印演示：</font></h2>
<p> 当打印页数超级多（上千页）时，如果用单页循环打印，会因为在操作系统中产生太多的</p>
<p>打印任务而影响性能；如果用NewPage分页方式打印，则会因为一次性占用太多的系统资源而</p>
<p>需要等待很长时间...</p>
<p>
解决问题的办法是采用折中处理，既分组完成，每组完成一部分，循环执行组打印。</p>
<p>下面演示一组打印预览10页，分50组循环实现500页的学位证书套打：</p>
<p>（在分组打印模板中，需要用ADD_PRINT_TEXTA函数，为每一个对象起个类名）</p>
