try this

  - (IBAction)Print:(id)sender {
    [self searchForPrinters];
   }
 - (void) searchForPrinters
  {

  if (NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_7_1)
  {
         UIPrinterPickerController *printPicker = [UIPrinterPickerController   printerPickerControllerWithInitiallySelectedPrinter:nil];
    [printPicker presentAnimated:YES completionHandler:
     ^(UIPrinterPickerController *printerPicker, BOOL userDidSelect,    NSError *error)
         {
         if (userDidSelect)
           {
             //User selected the item in the UIPrinterPickerController and got the printer details.

             [UIPrinterPickerController printerPickerControllerWithInitiallySelectedPrinter:printerPicker.selectedPrinter];

             //Here you will get the printer and printer details.ie,
             // printerPicker.selectedPrinter, printerPicker.selectedPrinter.displayName, printerPicker.selectedPrinter.URL etc. So you can display the printer name in your label text or button title.

             [btnSettingsPrint setTitle:printerPicker.selectedPrinter.displayName forState:UIControlStateNormal];

             NSURL *printerURL = printerPicker.selectedPrinter.URL;

         }
     }];
}
 }

 -(void)printYourItem :(NSData*)data
 {
 if (NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_7_1)
  {
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    UIPrinter *currentPrinterObj = [UIPrinter printerWithURL:[NSURL URLWithString:[defaults stringForKey:@"YouKeys"]]];

    UIPrintInteractionController *controller = [UIPrintInteractionController sharedPrintController];

    if(currentPrinterObj)
    {
        [controller printToPrinter:currentPrinterObj completionHandler:^(UIPrintInteractionController *printController, BOOL completed, NSError *error)
         {
             if(completed)
             {
             }
             else
             {
                 NSLog(@"FAILED! due to error in domain %@ with error code %u", error.domain, error.code);
             }
         }];
    }
}
}
