Query: waterproof labels

I was told in a email question to the seller that these labels were waterproof on ink jet printer. They are not. The package specifies they only work on laser jet. The seller would not take a return of the labels and told me I should have done more research on the product and that the buyer should beware. Not a good Amazon merchant. I can not speak as to how the labels would work on a laser printer.
