What is the highest dpi I can use to print index size photos to view thru a telescope viewer ?
I will be placing the pictures in the view finders. Most of these view finders are purchased at most amusement parks. The ones I purchased in the past are made with slide film but I want to print on the spot pictures at the highest dpi so you can view your images clearly. Just want to know if this is possible with the hp photosmart D7260. It can be done I just need to find the right printer.. Thank you
It sounds like you need to venture into the world of professional printers.
Multiple inks (consumer level ones only have 4)
High quality source image.
You'll be printing on transparency, so you'll have to search out a printer that can do that well.
Good luck.
