Mary Ann, I had wondered about that. Years ago I marked V. blinds with a p. marker and they would fade so.
The only problem I have with my Brother labeler is it seems to waste a lot of tape between names. It spits out almost a blank inch!! What is with that? I am sure there is a way to change the settings some how.
I have also found that my tape is almost 1/2 price at Amazon instead of Staples
