How to print an image to its exact size in iOS application?

Question

I am printing different images in my application. problem is printer always print the image in the whole page. if image size is very small printer print in the whole page and it looks very bad. i am using the following code for printing image:-

        NSData *dataFromPath = UIImageJPEGRepresentation(croppedImage, 1.0);
    if(printController && [UIPrintInteractionController canPrintData:dataFromPath]) {

        printController.delegate = self;
        UIPrintFormatter *my=[[UIPrintFormatter alloc]init];
        UIPrintInfo *printInfo = [UIPrintInfo printInfo];
        printInfo.outputType = UIPrintInfoOutputGeneral;
        printInfo.jobName = @"print image";
        printInfo.duplex = UIPrintInfoDuplexNone;
        printController.printInfo = printInfo;
        printController.showsPageRange = YES;
        printController.printingItem = dataFromPath;
        [printController presentFromRect:_btn_ShareAction.frame inView:_btn_ShareAction.superview animated:YES completionHandler:^(UIPrintInteractionController *printInteractionController, BOOL completed, NSError *error) {
            if (!completed && error) {
                NSLog(@"FAILED! due to error in domain %@ with error code %ld", error.domain, (long)error.code);
            }
        }];

    }

so i want a solution that allways print image according to it size and not allways take the whole page. — Dheeraj Kumar, Jul 11 '14 at 07:42

Instead of using printingItem you can use the printPageRenderer property and implement your own printing logic, which will enable you to print at the exact location and size as you wish.
