itext通过pdf模板填充数据并调用打印机打印

使用itext5对生成的pdf模板进行编辑填充数据，一种是通过绝对定位去做，简单的可以，通用性太差，第二种是通过pdf域来填充字段，通用性很强

在使用过程中遇到的问题：

网上都是通过这种字体设置中文的，在生成pdf之后，格式一切都正常，但是用java代码直接调用打印机打印后会出现填充的数据格式和生成的pdf格式不一样

BaseFont baseFont = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);

解决方法，添加宋体字体文件，直接调用添加的文件就正常了

String path2 = Thread.currentThread().getContextClassLoader().getResource("SIMSUN.TTC").getPath();
BaseFont baseFont = BaseFont.createFont(path2 + ",1", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
