For the best chance of success for long lasting prints consider the following: use a pigment based printer, 100 % cotton paper with no optical brightening agents, spray your prints with a protective coating to insure that the inkjet emulsion doesn't continue to absorb airborne contaminants, and make sure that your final print is sealed in a frame, hung or stored in an environment that isn't too extreme and away from bright sunlight.
