爱普生TM-T70 Java打印

Question

我需要使用Java打印到Epson TM-T70打印机（以太网版本）。我无法找到关于此的文档。哪种方法最简单？也许使用JavaPOS？有一些例子吗？

谢谢。

我们的POS机，我能够做到：

/* (non-Javadoc) 
* @see be.intoit.pos.epsonagent.commands.Command#execute() 
*/ 
public void execute() throws Exception { 
    DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE; 

    StringBuilder builder = new StringBuilder(); 
    builder.append(toPrint); 
    builder.append(EscapeCodeUtil.createEscapeCode(10)); 

    PrintRequestAttributeSet aset= new HashPrintRequestAttributeSet(); 
    aset.add(new MediaPrintableArea(100,400,210,160,Size2DSyntax.MM)); 


    InputStream is = new ByteArrayInputStream(builder.toString().getBytes("UTF-8")); 

    Doc mydoc = new SimpleDoc(is, flavor, null); 


     PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService(); 

     //print using default 
     DocPrintJob 
       job = defaultService.createPrintJob(); 
       job.print(mydoc, aset);  

} 

哪里的UTIL类是：

public class EscapeCodeUtil { 

public static String createEscapeCode(int ... codes) 
{ 
    StringBuilder sb = new StringBuilder(); 

    for(int code : codes) 
     sb.append((char) code); 

    return sb.toString(); 
} 
}
