JPS: Printer Discovery w/ Port settings

Posted: Sep 27, 2002 9:28 AM

I thought JPS was just the API I was looking for. I could finally discover printers available to a workstation.

However, I would also like to be able to retrieve the ports these printers are using. Any ideas? Is there something I missed in the docs? Any third party solutions out there that I haven't found?

For example:
A Windows local printer may be "LPT1"
A Windows network printer "\\server\printername"
Linux local "/dev/lp0"

Ive looked through the attributes and a couple looked promising (Destination, PrinterLocation) but "out.prn" and null were returned, respectively.

Any comments welcome. Even "It Can't be Done, you Moron"

I don't know if you have solved your problem, but here
are some ways of doing it.

import javax.print.*;
import java.awt.print.*;

public class FindPrinter
{ public static void main(String[] args)
{

PrintService ps = PrintServiceLookup.lookupDefaultPrintService();
String ss = ps.getName();
System.out.println( "Default printer : " + ss );

PrintService[] pservices = PrinterJob.lookupPrintServices();
System.out.println( "Installed printers:");
for (int i = 0; i < pservices.length; i++)
{
System.out.println( "\t\tPrinter " + i + " \"" + pservices[ i ] + "\"");
}

System.out.println( "Printer: \"" + ps.getName() + "\"");

System.out.println( "Printer: \"" + pservices[ 0 ].getName() + "\"");

} // End main
} // End class

I don't know about ports yet, but that must be possible too.
