I'm trying to print the addresses for the guests of our wedding on the envelopes and am having a lot of trouble. My printer keeps jamming or we can get the address to be in the right place when we can get it to print. I was thinking about resorting to buying clear labels and printing on those and then placing the labels on the envelopes to be mailed, but I've heard you're not supposed to do that? Does anyone know the etiquette behind this??? HELP!
