Owining a large printer probably will not save a someone a lot of money per se. Replacing the full set of ink cartridges is over $200.00. You will not be buying cheap ink to replace the cartridges either because you want your color spot on and if you are doing archival prints, you will be using pigment inks anyway. Hahnenmuhle or any good art paper will cost anything from $3 to $10 per sheet or so depending on size and quality.

What it will do is give you control over how your prints look. Once you have your camera, computer and printer all coordinated, what you see is what you get. A well made print is a beautiful thing!
