I keep having to explain this, you see unfortunately I cannot make this printer friendly by the usual means, ie. communicating with the printer. I just need a few pointers so I can adjust it and make the best guess I can with my monitor and photoshop. It looks ok on my phone now that I managed to work out how to turn the backlight on without it defaulting to off again before I opened the pictures.
I'm also looking to scale this down in size and up the DPI from 72 to 300, as that is part of the requirement. Maybe I can adjust the Y, or the contrast somehow to make it look more printer friendly, and maybe even better anyway...
