<p>A thermal printing machine (30) is provided with a releasably attachable tape cassette (1) which holds the tape (5) on which an image is placed. The cassette includes a memory circuit component (15) which includes at least two separate memory areas. The first area (65) contains a first value which is read by the printing machine; the second area (75) contains a second value which is placed on the cassette as a result of the first value having an algorithm applied to it. When the cassette (1) is installed in the machine, the machine applies the algorithm to the first value and checks this against the second value. This process is followed in order to see if the cassette (1) contains a compatible tape for that machine.</p> |
