After searching lot i got the answer , you have to change the PrinterAttributes Refer this link

And i android code change is

 PrintAttributes.Builder builder = new PrintAttributes.Builder();
 builder.setMediaSize( PrintAttributes.MediaSize.ISO_A5);
 PrintJob printJob = printManager.print(jobName, printAdapter, builder.build());

That's it.
