Paper cutting mechanisms

A paper cutting mechanism for cutting paper in a printing device, the paper having a first lateral side and a second lateral side spaced from the first lateral side, comprising:

• a cutting device movingly coupled to the printing device;
• and
• a retention mechanism configured to rotate when mechanically interacting with the cutting device to selectively deploy the retention mechanism to retain the paper, the retention mechanism including:
• 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;
• a rotation shaft extending from the elbow transverse to a plane defined by the first arm and the second arm;
• and
• a retaining portion connected to the rotation shaft and configured to selectively retain the paper when the cutting device mechanically interacts with the trigger.

A paper cutting mechanism for cutting paper in a printing device including a channel including a first end and a second end, comprising:

• a belt-drive mechanism;
• a cutting device coupled to the belt-drive mechanism;
• and
• a retention mechanism configured to rotate when mechanically interacting with the cutting device to selectively deploy the retention mechanism to retain the paper, the retention mechanism including:
• a trigger including a pivot, a first arm extending from the pivot, and a second arm extending from the pivot offset from the first arm;
• a rotation shaft extending from the pivot transverse to a plane defined by the first arm and the second arm;
• and
• a retaining portion connected to the rotation shaft and configured to selectively retain the paper when the cutting device mechanically interacts with the trigger.
