具体怎么调用，每个方法注释写得都很清楚了，至于怎么排版，要看纸的宽度了，然后自己计算字符的长度进行设置，下面是一个异步调用的例子，下面方法仅仅是一个例子，请无视其他无用代码。

页面排版实现，首先得知道打印纸的宽度，还有你要在纸上显示几列，譬如我这个方法 我显示了4列，所有我先根据打印纸的宽度 先设置好每一列的大致宽度，如果该列的字符长度大于设置好的 可以设置换行，如果小于，为了排版整齐 可以补空格，大致实现原理就是这样。

  // 粗略计算打印纸上每个字段占的长度

  private int wlname = 18;

  private int wlnum = 6;

  private int wlunit = 7;

  private int wlprice = 9;
