Although I don't use it often, I've lost the AC adapter, so it runs on six AA batteries. It supports 6-18mm tapes, and currently has an 18mm white tape installed, which is about 80% full, so please use it. I've taken pictures of the printed tape to show it can print. I think it's clean with no blurring. I haven't used all the functions, but I've confirmed that basic printing works. This is a used item, so I'm selling it as junk. I will not accept returns or complaints, so please understand this before purchasing.
