I got sample from the 800 sent to me supposed to be scratch resistant sadly they were not very so didn’t bother at the price. That was a while ago though, may be better now. I would definitely get samples sent first. I am going to try adhesive outdoor paper first as I am too looking for a coloured label printer.
I have an older zebra thermal printer and have put strips of vinyl through it with resin mix ink, speed pretty impressive and durability excellent. as good as it gets. I don’t know how long it would last the thickness of the vinyl is more than is supposed to go through them.
