The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth.

I know this post is old, but just in case anyone is looking for it, there is a project called NYXImagesKit that does what you are looking for.

All you have to do is:
NYXProgressiveImageView * imgv = [[NYXProgressiveImageView alloc] init];
imgv.frame = CGRectMake(0, 0, 320, 480);
[imgv loadImageAtURL:[NSURL URLWithString:@"http://yourimage"]];
[self.view addSubview:imgv];
[imgv release];
Also, a good option is to save your images as interlaced so that it loads with low quality and improve with the download. If the image is normal it is loaded from top to bottom.
