Query: good for a while, then nothing

worked great for a few months, then started sucking batteries. every time i pulled it out of the drawer (once a month or so) i'd have to put in a new set of batteries just to get it to print. now it won't print anything, even with fresh batteries (it still feeds the tape through though). so, i'm going to be looking for a new label maker. yay.
