java 打印机打印和开钱箱
最近在网上查了一下，用java实现了打印机打印以及打印机开钱箱功能。代码如下：
String os = System.getProperty("os.name");
if(os.contains("Windows")){
//Windows
try {
PrintWriter pw = new PrintWriter("lpt1");
//普通打印
pw.write("English-Windows"+"\n");
pw.write("中文-Windows"+"\n");
//打印机开钱箱指令
char[] c = {27,'p',0,60,240};
pw.write(c);
pw.write("\n");
pw.flush();
} catch (FileNotFoundException ex) {
Logger.getLogger(PrintTest.class.getName()).log(Level.SEVERE, null, ex);
}
}else{
//Linux
try {
FileOutputStream fos = new FileOutputStream("/dev/lp0");
//普通打印
fos.write("English-Linux\n".getBytes());
fos.write("中文-Linux\n".getBytes("GBK"));
//打印机开钱箱指令
char[] c = {27,'p',0,60,240};
for(int i=0;i<c.length;i++){
fos.write(c);
}
fos.write("\n".getBytes());
fos.flush();
} catch (IOException ex) {
Logger.getLogger(PrintTest.class.getName()).log(Level.SEVERE, null, ex);
}
}
