Media capacity—or the maximum label volume that the printer can load—also dictates efficiency. Larger media loads mean fewer refills and less reloading time. You may not feel its impact when your labeling requirements are still few, but you will notice the difference when they are already picking up.
Media capacity can be gauged by a label roll's outer diameter. The larger is the diameter, the bigger is the printer's label-loading capacity. In Brother and Dymo's case, their label roll sizes are expressed as the number of labels per roll.
