Create image from image and label

I would like to print an image that I would include the image and add the text from a label.

Here is the code I have to print the image.

-(void)printItem {

    NSString *path = [[NSBundle mainBundle] pathForResource:@"St_Trop" ofType:@"jpg"];
    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];

    }
}

What's the question? Are you just trying to get an image with text? If so, you'll probably want to use

UIGraphicsBeginImageContext and UIGraphicsGetImageFromCurrentImageContext

You'd also want to look into the NSString convenience methods for drawing text to a CG context.

I have managed to create the image now. I am trying to print this image but just can't work out how. Is there any way I can create a path for the created image?

I'm not sure what you mean by a path for the image? When you use UIGraphicsGetImageFromCurrentImageContext, it returns a UIImage. It's not written to file, it's written to memory, so you don't need a path for it.
