It’s true, there are limitations when printing, so we are glad you asked.  In order to verify that your font size is large enough for your label, we recommend printing the label out at it’s proper size (if you are using one of our templates, that should be at 100% or no scale).  If you can read it clearly from your home printer, it will show up perfectly on our industrial ones.  If the font is sort of pushed together and hard to decipher, you may want to bump the sizing up a bit. We recommend going no smaller than 7pt type if you want your friends with glasses to be able to read it.
