What do you want to print on the label Sarah? That where you need to start to determine features.

My suggestion for features:
-2 or 3 line printing
-can handle lots of characters per label. Mine does 59 and is good for most tags.
-uses tape width that matches your plant tags
-has power adapter (too many batteries polluting our world)
Be sure to check if you can adjust the Tape Margin Function. This allows you to adjust the amount of blank tape on the left and right sides of you text. With the smallest setting, my model 1750 wastes almost 1" at the beginning of
every label. I try to print several labels at one time, so I only waste it once - but it still hurts!
Good luck shopping!
