- (void)printAndSave
{
    webViewHeight = [[self.myWebView stringByEvaluatingJavaScriptFromString:@"document.body.scrollHeight;"] integerValue];
    CGRect screenRect = self.myWebView.frame;
    double currentWebViewHeight = webViewHeight;
    while (currentWebViewHeight > 0)
    {
        imageName ++;
        UIGraphicsBeginImageContext(screenRect.size);
        CGContextRef ctx = UIGraphicsGetCurrentContext();
        [[UIColor blackColor] set];
        CGContextFillRect(ctx, screenRect);
        [self.myWebView.layer renderInContext:ctx];
        UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();
        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsDirectory = [paths objectAtIndex:0];
        NSString *pngPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%d.png",imageName]];
        if(currentWebViewHeight < 460)
        {
            CGRect lastImageRect = CGRectMake(0, 457 - currentWebViewHeight, self.myWebView.frame.size.width, currentWebViewHeight);
            CGImageRef lastImageRef = CGImageCreateWithImageInRect([newImage CGImage], lastImageRect);
            newImage = [UIImage imageWithCGImage:lastImageRef];
            CGImageRelease(lastImageRef);
        }
        [UIImagePNGRepresentation(newImage) writeToFile:pngPath atomically:YES];
        [self.myWebView stringByEvaluatingJavaScriptFromString:@"window.scrollBy(0,460);"];
        currentWebViewHeight -= 460;
    }
}
