在页面打印后不可见边框周围的边框

我有几个字段的简单窗体，用户插入值后可以点击按钮打印并打印页面。在页面打印后不可见边框周围的边框

一切工作正常，除非实际打印执行输入字段边框丢失。

这是形式

<form name="hongkiat" id="hongkiat-form" method="post" action="#"> 

    <div id="wrapping" class="clearfix"> 

     <section id="aligned"> 

      <div class="block"> 
       <label for="name">Full Name</label> 
       <input type="text" name="name" id="name" placeholder="" autocomplete="off" tabindex="1" class="txtinput"> 
      </div> 
      <div class="block"> 
       <label for="name">Email Address</label> 
       <input type="email" name="email" id="email" placeholder="" autocomplete="off" tabindex="2" class="txtinput"> 
      </div> 
      <div class="block"> 
       <label for="name">Statement</label> 
       <textarea name="message" id="message" placeholder="" tabindex="5" class="txtblock"></textarea> 
      </div> 
     </section> 

    </div> 
    <section id="buttons"> 
     <input type="button" value="Print This Page" class="resetbtn" id="resetbtn" onClick="window.print()"> 
     <br style="clear:both;"> 
    </section> 
    </form>

这是CSS
