在打印java之前设置边距和字体？

Question

我想从txt文档创建java中的打印服务，我需要在打印前设置边距和字体。

方法printjob工作正常，但结果边距和字体不符合预期。如何解决我的问题？  :(
对不起我的英文:)感谢以前的帮助

public void test() {
            FileInputStream inStream = null;
            try {

                return;

            String printerName = "\\\\\\192.168.1.8\\EPSON L210 Series";

            PrintServiceAttributeSet printServiceAttributeSet = new HashPrintServiceAttributeSet();
            printServiceAttributeSet.add(new PrinterName(printerName, null));

                    break;

            }
        }
