You can also freeze your printing paper. B&W anyway, the colour printers here will tell if colour paper can be frozen, but I don't see why not. Don't freeze Polaroid film. Although after all the film I have stuffed into mine, there no room for food, let alone paper. When I buy film it goes into the freezer, the oldest film get pulled into the fridge, and the oldest in the fridge gets put into the camera case. Rotate your stock.
Letting it reach room temp before using is important. I got a bunch of Kodak colour 120 film at a $1 a roll than had expired back in 92. I pull a couple rolls out every fall, still works good.
