how to lookup network printers

I'm not looking to get printers that are installed on the local system, I'm looking at finding printers within the network. I've tried the following:

AttributeSet aset = new HashAttributeSet();
aset.add(new PrinterName("\\\\PRINT_SERVER\\PRINTER_NAME", null));
PrintService service[] = PrintServiceLookup.lookupPrintServices(null, aset);

But this only gets me the local printers isntalled on the machine that the code is running on. What i'm looking for is to get other network printers, by name, from across the network.

Any help would be greatly appreciated.
