JAVA打印机打印TXT

Question

小弟刚接触JAVA打印机打印TXT，困惑许久，求一段实例代码，要求中文不乱码。意思就是把TXT以文件形式放入Windows打印队列。

Answer 1

Java的打印API主要存在于java.awt.print包中。而jdk1.4新增的类则主要存在于javax.print包及其相应的子包javax.print.event和javax.print.attribute中。其中javax.print包中主要包含打印服务的相关类，而javax.print.event则包含打印事件的相关定义，javax.print.attribute则包括打印服务的可用属性列表等。例子：

Answer 2

public void printFile(String fileName){
        StringBuffer buffer = new StringBuffer();
        try {
            BufferedReader reader = new BufferedReader(new FileReader(fileName));
            while(reader.ready()){
                buffer.append(reader.readLine());
            }
            System.out.println("输出文件内容的结果为：" + buffer.toString());
            reader.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
