打印不光要能打印内部的单据，对于检验的打印还有外送回传的PDF报告也需要能够打印，所以需要把打印PDF文件整合进来，为此给打印元素绘制协议增加PDF类型的元素。
定义如下，由绘制协议按地址下载文件后和其他打印元素整合：
/**
* PDF文件的ftp或http全路径。用英文逗号分隔两个A5PDF路径打印会自动合并为一个A4。一个A5路径后跟个英文逗号，会把PDF转A4纸打印，会把PDF每页提取成大图当一页打印
*
* @param httpOrFtpPath pdf文件的下载路径
* @return
*/
public static PrintElement DrawPDF(String httpOrFtpPath) {
PrintElement ret = new PrintElement();
ret.DataField = httpOrFtpPath;
ret.PrintType = "PDF";
return ret;
}
整合协议
PDF文件在文件服务放一个
