I know there's not really, but I just grabbed my Trusty Label Printer (yet another lp2844) from eBay, and it turns out these things are useless without labels.
Darn the luck.
Now, it'd be nice if I could use just one standard labely label (so's not to swap reels in the printer, for I am a Lazy Bastard (TM)) for the bulk of my labeling tasks, which as far as I can tell will be: sticking on bags that contain kits, and sticking on packages for shipping. Right now 4"x6" bags seem like a decent bag-for-kit size, so something smaller than that sounds reasonable, but I don't want to shoot myself in the labeling foot and have someone say 'You got 2"x3" labels!? YOU FOOL!", so I thought I'd throw it out there and see if anyone had advice.
