Printing on self stick envelopes????

I ordered self stick envelopes in the interest of saving time. I planned on printing the addresses on them..but the self stick has a flap that sticks out & looks like my printer will eat it up.

Has anyone printed on self-stick envelopes?? Did it work???

I have no time for calligraphy and my handwriting isn't the greatest. I don't know what the f**k I'm going to do now ughhhh

i used clear labels....
i know i know tottaly tacky but i had no time to get them all addressed anyother way.... and honestly it really didn't look that bad
