Where do you get labels for your Zebra 2844 thermal label printer? The free UPS ones work well, but UPS limits them, they have a UPS logo on them, and I don't ship via UPS. I tried some very cheap ones from Amazon, but the adhesive isn't strong enough and the labels actually tend to fall off the packages. I could keep at it with trial and error, but has anyone found a low-priced 2844 label they like?
