iPhone/iPad AirPrinting Tutorial in 3 steps

Step 1:

Start Xcode and make a New Project – Select View-based Application – I call it AirPrinting.

Add an image to your project – I added demo.png – Here is the image

Step 2:

Go to AirPrintingViewController.h and add the following code

#import <UIKit/UIKit.h>   @interface AirPrintingViewController : UIViewController <UIPrintInteractionControllerDelegate>{   }   -(void)printItem;   @end

Next in AirPrintingViewController.m add the following code

#import "AirPrintingViewController.h"   @implementation AirPrintingViewController   -(void)printItem {       NSString *path = [[NSBundle mainBundle] pathForResource:@"demo" ofType:@"png"];     NSData *dataFromPath = [NSData dataWithContentsOfFile:path];       UIPrintInteractionController *printController = [UIPrintInteractionController sharedPrintController];       if(printController && [UIPrintInteractionController canPrintData:dataFromPath]) {           printController.delegate = self;           UIPrintInfo *printInfo = [UIPrintInfo printInfo];         printInfo.outputType = UIPrintInfoOutputGeneral;         printInfo.jobName = [path lastPathComponent];         printInfo.duplex = UIPrintInfoDuplexLongEdge;         printController.printInfo = printInfo;         printController.showsPageRange = YES;         printController.printingItem = dataFromPath;           void (^completionHandler)(UIPrintInteractionController *, BOOL, NSError *) = ^(UIPrintInteractionController *printController, BOOL completed, NSError *error) {             if (!completed && error) {                 NSLog(@"FAILED! due to error in domain %@ with error code %u", error.domain, error.code);             }         };           [printController presentAnimated:YES completionHandler:completionHandler];       } }   - (void)viewDidLoad {     [super viewDidLoad];     UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];     [btn addTarget:self action:@selector(printItem) forControlEvents:UIControlEventTouchDown];     [btn setTitle:@"PRINT" forState:UIControlStateNormal];     btn.frame = CGRectMake(0, 100, 320, 50);     [self.view addSubview:btn]; }   @end

Step 3:

Build and Run – You will see a print button – Click the print Button and you will see UIPrintInteractionController popup – Go ahead and Print.

Here is the entire Code
