Claim:
In combination, a label printing apparatus and a cassette, the cassette comprising a supply of label material and a brake positioned downstream of the supply of label material and upstream of an outlet for the label material, said brake having a first position and a second position, wherein in said first position said label material is clamped by said brake such that the label material is prevented from coming out of the cassette, and in said second position said label material is removable from said cassette via the outlet; and the label printing apparatus comprising a print head, a cassette receiving bay and a brake activation mechanism, said brake activation mechanism arranged to interact with a brake of the cassette, wherein said brake activation mechanism comprises a brake actuating member; wherein relative movement between the cassette and the brake actuating member, after the cassette is received in said cassette receiving bay, causes the brake actuating member to enter an opening in the cassette; and wherein relative movement between the cassette and the brake actuating member, when the brake actuating member is located in the opening, moves the brake, whereby said brake activation mechanism causes said brake to move from the first position to the second position.
