Changing the PPI tag in the image file is *not* what changes the print.

nospam
yes it does.

Poor nospam. We can post 30 different identical copies of an image file, with only the PPI tag being different. Anything from 7 to 7000 will do. When loaded into an editor... the image data will be exactly the same for every one of them.

Because chaning the PPI tage in the image file does nothing.
