That's very interesting. You are quite right to be concerned about the longevity of your self-printed photos....these will begin to fade (especially in sunlight) after about five years.
I have a Canon 'Selphy' photo printer. It uses a rather unique process which involves the final stage consisting of applying a protective coat. Canon claim that these prints will last for 100 years. Prints are waterproof & virtually indestructible.
Limitations are: It's necessary to use only Canon paper & ink cartridge and the maximum size is only 6" x 4".
An example, but as always it's best to shop around: www.argos.co.uk/static/Product/partNumber/1574607.htm
