My program


package test;

import javax.print.*;
import javax.print.attribute.*;
import javax.print.attribute.standard.*;
import java.io.*;

/*
import javax.print.event.*;
*/

public class PrintStatus {

// A utility method to look up printers that can support the specified
// attributes and return the one that matches the specified name.
public static PrintService getNamedPrinter(String name,
PrintRequestAttributeSet attrs) {

PrintService[ ] services =
PrintServiceLookup.lookupPrintServices(null, attrs);

if (services.length > 0) {
if (name == null) return services[0];
else {
for(int i = 0; i < services.length; i++) {
if (services[i].getName( ).equals(name)) return services[i];
}
}
}

return null;
}

// List details about the named printer
public static void queryPrinter(String printerName,
PrintRequestAttributeSet attributes) {

// Find the named printer
PrintService service = getNamedPrinter(printerName, attributes);
if (service == null) {
System.out.println(printerName + ": no such printer capable of " +
"handling the specified attributes");
return;
}

// Print status and other information about the printer
System.out.println(printerName + " status:");
Attribute[ ] attrs = service.getAttributes( ).toArray( );

System.out.println("Attributes length----------" + attrs.length);
for(int i = 0; i < attrs.length; i++)
System.out.println("\t" + attrs[i].getName( ) + ": " + attrs[i]);
}

public static void main(String[ ] args) throws IOException {

if( args.length == 0 ) {
System.out.println("Usage: java PrintStatus <printer-name1> [<printer-name2> ...]");
return;
}

String printerName;
PrintRequestAttributeSet attributes = null;

for( int i = 0 ; i < args.length ; i++ )
{
printerName = args[i];
queryPrinter(printerName, attributes);
}
}

public static void main1(String[ ] args) throws IOException {

String printerName;
PrintRequestAttributeSet attributes = null;

printerName = "printer470";
/* // printer470, printer4550
attributes = new HashPrintRequestAttributeSet();
attributes.add(Chromaticity.COLOR);
*/

queryPrinter(printerName, attributes);

}
}
