It's possible. With the changes of barometric pressure, humidity, and tempature used on the curling iron....
ok, I was kidding about the iron..
usually the print will hang out straight. But with the events of weather and where it is hung..
You will experience what some like to explain "the aliveness" [sorry cpt english], of the print.
Paper isn't "alive" but it does react, same as a board... with changes of humidity, the moisture content of the print or board will increase or decrease resulting in swelling or shrinkage. Usually it is very small in a print, and then again it can be quit dramatic in something like handmade paper that is as thick as 12-ply but with only half the densitiy.
If the paper is hardface rolled and shelled (usual for posters and highspeed printing) then the you can expect the changes to be less than noticable.
