Generally a PrintService will be looked up like in the below snippet
PrintService defaultPrintService = PrintServiceLookup.lookupDefaultPrintService();
DocPrintJob printerJob = defaultPrintService.createPrintJob();
But is there a way to create a new PrintService by specifying the ip address of the printer
for eg:
String myPrinter = "10.101.111.11\\Eighth Floor Ricoh Printer";
PrintService myPrntSrvc = create a service with myPrinter
printJob.setPrintService(myPrntSrvc);
