使用Java工厂创建一个打印服务器

import java.io.BufferedOutputStream;
import java.io.FileOutputStream;
import java.io.OutputStream;

import javax.print.DocFlavor;
import javax.print.StreamPrintService;
import javax.print.StreamPrintServiceFactory;

public class Main {
public static void main(String[] argv) throws Exception {

StreamPrintServiceFactory[] factories = StreamPrintServiceFactory
.lookupStreamPrintServiceFactories(null, null);

OutputStream fos = new BufferedOutputStream(new FileOutputStream("outfile.ps"));
StreamPrintService service = factories[0].getPrintService(fos);

}
}
