Abstract: A tape cassette is used in a printing device with a drive shaft. The tape cassette includes a cassette casing which houses a printing tape and defines a feed path through which the tape moves in a feeding direction. The cassette casing includes a head recess adapted to receive a print head of the printing device. The cassette casing forms a generally rectangular shape that is bounded by four corners, but also includes a recess for receiving the drive shaft adjacent a first corner of the four corner of the cassette casing downstream of, and spaced from, the head recess in the feed direction. The cassette casing defines a first positioning hole adjacent the drive shaft and a second positioning hole spaced from the drive shaft, the first and second positioning holes each communicating with a corresponding pin of the printing device to ensure a proper positioning of the cassette casing within the printing device.

Abstract: A tape-like label printing device capable of accurately setting a print start point of origin in case plural times of printings are required to the identical printing area of a tape by rewinding the tape for respective printing. A print start process is executed by manipulation of a print key. A ribbon color of a ribbon cassette is detected (S40). If the cassette has a desired ribbon color (S42:Yes) print data is retrieved. (S45). If the printing tape is detected by a tape detection sensor (S46), a message prompting the cutting is displayed (S48). When the tape is cut(S48, S46:Yes), the printing tape is fed in the tape feeding direction (S49), and the print start point of origin is set which is indicative of the printing position of the thermal head relative to the printing tape when the leading edge of the printing tape is detected by the tape detection sensor.
