Question

I currently retrieve some printer information about the possible media trays with this code snippet:

 Media med[] = (Media[])printService.getSupportedAttributeValues(Media.class, null, null);
 if( med != null ) {    
     for (int k=0; k<med.length; k++) {
          sb.append("Name : " + med[k].getClass() + " - Value : " + med[k].getValue() +
                " - Name : " + med[k].getName()+"\n" );
     }
 }

Sadly, this just returns some tray numbers, which I find relatively useless:

Name : class javax.print.attribute.standard.MediaSizeName - Value : 40 - Name : media
Name : class javax.print.attribute.standard.MediaSizeName - Value : 41 - Name : media
Name : class javax.print.attribute.standard.MediaSizeName - Value : 42 - Name : media
... more ...
Name : class sun.print.Win32MediaTray - Value : 5 - Name : media
Name : class sun.print.Win32MediaTray - Value : 25 - Name : media
Name : class sun.print.Win32MediaTray - Value : 26 - Name : media
Name : class sun.print.Win32MediaTray - Value : 27 - Name : media

How can I retrieve useful names?

Answer 1

This will give you all printer properties, including tray names

String printName = "HP Officejet Pro 8500 A910 (Network)";
AttributeSet aset = new HashAttributeSet();
aset.add(new PrinterName(printName, null));
PrintService[] services = PrintServiceLookup.lookupPrintServices(null, aset);
for (int i = 0; i < services.length; i++) {
  PrintService service = services[i];
  System.out.println(service);
  DocFlavor flavor = DocFlavor.SERVICE_FORMATTED.PAGEABLE;
  Object o = service.getSupportedAttributeValues(Media.class, flavor, null);
  if (o != null && o.getClass().isArray()) {
    for (Media media : (Media[]) o) {
      System.out.println(media + " ID: " + media.getValue() + "\t" + media.getClass().getName());
    }
  }
}
