  • Patent number: 6428225
    Abstract: A printer media cassette includes a movable arm which defines a desired path for media stock to facilitate insertion and removal of the cassette from a printer. The cassette also includes a tensioner arm for providing slack in the media path within the cassette to account for slippage between a feed roller of the printer and the media. Latching mechanisms on the cassette cooperate with latching mechanisms on a printer to assure proper installation of the cassette within the printer.

  • Patent number: 5779370
    Abstract: An apparatus for printing labels having a tacky side and a non-tacky printable side. The apparatus comprises a print head for printing indicia on the printable side of the labels, and a print roller disposed in close proximity to the print head. The print head is thus enabled to print indicia on the labels when the labels are supported by the print roller, the print roller having at least one annular recess in its surface thereof. The apparatus further comprises at least one elongated stripper element retained in and extending from the recess such that upon rotation of the roller, the label is transported to the stripper element. The stripper element thereby lifts the label from the surface of the roller and the label is removed from the print roller.
