If you’re really ambitious you can create a slick template for the MR-1212 series of labels. With Inkscape it’s an easy task to get Text on a curve. You may have to tweak the graphics a bit to get your labels centered, and your printer might not support full bleed printing. Full bleed printing means that the printer will print all the way out to the edge of the paper. If you don’t have a full bleed, the outside columns will be cut off at the edges of the labels.
