Automatic Selection of Printer not working!

According to the instructions that I got from experts exchange earlier, I tried to develop a class file for sending a print option to a particular printer without prompting for selection of printer. But when I try to press PRINT button an exception is coming and the print out is not appearing. Please go through the program and suggest a better solution. My aim is : There are 2-3 printers attached to a particular PC and a particular report print should go to a particular printer without a print dialog box.

sorry, please replace the code

DocPrintJob job = printServices[1].createPrintJob();

with this code

DocPrintJob job = printServices[0].createPrintJob();
