    Get PrinterStateReasons

    993856
      Hi,

      I want to run a printing job using java and before that I need to check printer State.(I found this thread on same problem but unsolved. Re: How to get a PrinterState ) Which means whether covers are open, Trays out of paper, Paper Jam etc. I see these things are available inside PrinterServiceAttribute PrinterStateReason PrinterStateReason . When I loop through attributes available in PrintService, PrintStateReason is null(Primarily PrinterStateReasons is null. because API documentation says PrinterSateReason is inside PrinterStateReasons). Following is what I try to do

      PrintService[] allServices = PrintServiceLookup.lookupPrintServices(null, null);
                
                for (PrintService ps : allServices){
                     AttributeSet attSet = ps.getAttributes();
                     
                     System.out.println("Available printers support attribute -> "+ ps.getName());
                     
                     PrinterState prnState = (PrinterState)ps.getAttribute(PrinterState.class);
                     
                     System.out.println("PrinterStats -> "+ prnState);
                     
                     log.info("Available printers support attribute -> ");

                for(Attribute att:attSet.toArray()){
                     String attName = att.getName();
                     String attValue = attSet.get(att.getClass()).toString();
                     System.out.println(attName + " : " + attValue);
                     log.info(attName + " : " + attValue);
                }
           }

      If printer is not supporting this attribute how can we check whether a particular printer supports this?

      Thank you
