I have a Canon photo printer at home that I got back in 2006. Off the top of my head, I can't remember which one - hopefully it won't be important for my question.
I printed out pictures to give to family of my older daughter when she was born (end of 2006). They were printed on Canon paper, probably the paper that came in the box with the printer. Since then, I've seen the pictures hanging up on relitives' fridges and they've yellowed. I don't use the printer much (I usually send out and have my pictures printed) and now I am even more hesitant to use it because of how the pictures look even two years later!
I am thinking it is a problem with the paper, since I printed them with borders and the borders are also yellowed (though the actual photo looks worse). Could the paper in the box have been old? It hadn't been opened until I bought it, so it shouldn't have been exposed to anything. Any other reason the pictures might have yellowed? I'd like to start printing my own photos again, but if they won't hold up for even two years, forget it!
