用java的api访问打印机

[songfuyu_1997]

我找了一段代码，可以用java的api访问打印机，没有运行过，不知道好不好用。我的机器上没有打印机，如何实现 运行我本地机器上的程序访问其他机器上的打印机 打印我机器上的 文件。这段代码应该怎样写？
程序代码如下：
import java.io.FileInputStream;
import java.io.FileNotFoundException;

import javax.print.Doc;
import javax.print.DocFlavor;
import javax.print.DocPrintJob;
import javax.print.PrintException;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import javax.print.SimpleDoc;
import javax.print.attribute.HashPrintRequestAttributeSet;
import javax.print.attribute.PrintRequestAttributeSet;
import javax.print.attribute.standard.Copies;
import javax.print.attribute.standard.MediaSizeName;
import javax.print.attribute.standard.Sides;

//import javax.print.attribute.standard.Sides;

public class Print {
public static void main(String[] args){
new Print();
// System.out.println("ok");
}
Print(){
FileInputStream psStream=null;
try {
psStream = new FileInputStream("cntxt.txt");
} catch (FileNotFoundException ffne) {
}
if (psStream == null) {
return;
}

DocFlavor psInFormat = DocFlavor.INPUT_STREAM.POSTSCRIPT;
Doc myDoc = new SimpleDoc(psStream, psInFormat, null);
PrintRequestAttributeSet aset =
new HashPrintRequestAttributeSet();
aset.add(new Copies(5));
aset.add(MediaSizeName.ISO_A4);
aset.add(Sides.DUPLEX);
PrintService[] services =
PrintServiceLookup.lookupPrintServices(psInFormat, aset);
if (services.length > 0) {
DocPrintJob job = services[0].createPrintJob();
try {
job.print(myDoc, aset);
} catch (PrintException pe) {}
}

}

}
