上一篇实现了粗略的打印元素绘制协议，并且写了打印示例和导出示例，趁着空隙时间完善一下打印。
首先元素构造函数默认初始化每个字段值
package LIS.Core.Dto;
/**
* 打印约定元素
*/
public class PrintElement {
/**
* 元素类型
*/
public String PrintType;
/**
* X
*/
public String PrintX;
/**
* Y
*/
public String PrintY;
/**
* 字体
*/
public String PrintFont;
/**
* 字体大小
*/
public String PrintFontSize;
/**
* 字体样式
*/
public String PrintFontStyle;
/**
* 长度
*/
public String PrintLength;
/**
* 宽度
*/
public String PrintWidth;
/**
* 高度
*/
public String PrintHeight;
/**
* 文本
*/
public String PrintText;
/**
* 数据字段
*/
public String DataField;
/**
* 特殊标志
*/
public String PrintFlag;
/**
* 停靠
*/
public String PrintAlignment;
/**
* 图片
*/
public String PrintImageFile;
/**
* 颜色
*/
public String PrintColor;
/**
* 旋转角度
*/
public String Angle;
/**
* 垂直显示
*/
public String IsVShow;
/**
* 业务ID
*/
public String BllID;
/**
* 构造
*/
public PrintElement()
{
PrintType="";
PrintX="10";
PrintY="10";
PrintFont="宋体";
PrintFontSize="10";
PrintFontStyle="";
PrintLength="10";
PrintWidth="20";
PrintHeight="20";
PrintText="";

PrintFlag="";

}

打印基础就更稳定了，业务只需要按要求控制输出数据就行了，可以结合设计器的保存数据和业务数据组装
