核心代码：

public class PrintService { 
    
        private static final Logger logger = LoggerFactory.getLogger(PrintService.class);
    
        /** * 打印 * @param in 文件流 * @param isDuplex 是否双页打印 * @param copies 份数 * @param isPortrait 是否竖打 * @throws Exception */

            }
            if(copies <= 0) {
                throw new TXException("打印份数不应小于0");
            }
    
            logger.info("打印文件: 是否双页打印: "+isDuplex+",份数: "+copies+"是否竖打"+isPortrait);
