Abstract
A printer cartridge suitable for use in a cartridge-based printer houses and dispenses a roll of label media. The cartridge includes a housing having a top wall and a bottom wall. A yoke pivotally mounted between the top and bottom walls for pivotable movement about a pivot axis includes a label media supply shaft for holding a roll of label media. The label media supply shaft has a longitudinal axis spaced from, and parallel, to the pivot axis. A label media drive roller is rotatably mounted between the top and bottom walls, and a biasing means biases the yoke toward the label media drive roller to maintain the roll of label media in contact with the label media drive roller and defines a beginning of a media path. In one embodiment, the yoke is adjustable to accommodate different label media widths.
