本文介绍了一个Java程序，该程序使用`javax.print`包中的类来查找系统中可用的打印服务，并列出每个打印服务的属性及支持的文档格式。

import javax.print.DocFlavor;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import javax.print.attribute.Attribute;
import javax.print.attribute.PrintServiceAttributeSet;
import javax.print.attribute.standard.PrinterName;

public class Main {
  static public void main(String args[]) throws Exception {
    PrintService pss[] = PrintServiceLookup.lookupPrintServices(null, null);
    for (int i = 0; i < pss.length; ++i) {
      System.out.println(pss[i]);
      PrintService ps = pss[i];

      PrintServiceAttributeSet psas = ps.getAttributes();
      Attribute attributes[] = psas.toArray();
      for (int j = 0; j < attributes.length; ++j) {
        Attribute attribute = attributes[j];
        System.out.println("  attribute: " + attribute.getName());
        if (attribute instanceof PrinterName) {
          System.out.println("    printer name: " + ((PrinterName) attribute).getValue());
        }
      }
      DocFlavor supportedFlavors[] = ps.getSupportedDocFlavors();
      for (int j = 0; j < supportedFlavors.length; ++j) {
        System.out.println("  flavor: " + supportedFlavors[j]);
      }
    }
  }
}
