NOTE Most Fabric Sheet will tell you NOT TO USE A LASER JET and if you do it will void any warranty that you have.
I have used printed treasures off and on for some time and no real isues. However we just got a new quilt shop and they used to do T-Shirts so they still have all of the equipment. They are doing the transfers (using the t-shirt method) for quilters now. It is possible if you have a t-shirt shop near you that they might also do this. It didn't seem anymore expensive than the treated fabric sheets and more permanent.
