Abstract

Paper cutting mechanisms for cutting paper in a printing device including a drive mechanism, a cutting device coupled to the drive mechanism, and a retention mechanism including a trigger and a retaining portion configured to mechanically interact with the cutting device to selectively deploy the retention mechanism to retain the paper. In some examples, paper cutting mechanism includes a trigger including an elbow, a first arm extending from the elbow, and a second arm extending from the elbow offset from the first arm, and a rotation shaft extending from the elbow transverse to a plane defined by the first arm and the second arm. In some further examples, the paper cutting mechanism includes a resilient member cooperatively coupled with a paper engaging end of the retaining portion.
