Depends. If you are using an older printer that uses dye inks, then yes. Framed or out of an album they will last a year or two. In an album in a dark place a bit longer. If you have one of the newer printers that uses pigment inks and you are using the right paper they will last a decade or two. I do not believe that even the pigment inks will last the 70 to 200 years some printer makers claim. All of the testing done on this is done in a lab simulating what they think is 70 to 200 years of light exposure. They do not take in to account the variations in pollution, atmosphere (drier vs. wetter conditions) and the like. But I do believe that these newer printers will make prints that last a decade or two.
Some printers to look at include:
The Epson R1800 The Epson R2400 The original Epson PictureMate (the new just released ones use dye inks and went from 6 colors to 4) The HP PhotoSmart 9180
Basically look for them talking about pigment based inks. It is of course important that you use real Epson, HP, Canon inks and paper. Using others totally throws the print life out the window. Meaning you just don't know then how long the prints will last.
