Modular print drive assembly and platen assembly

A platen latch assembly comprising:

• a latch arm defining a latch hook and a pivot end, wherein the latch arm is configured to rotate between a latched position and an unlatched position;
• a lock arm slideably coupled to translate along the latch arm between a locked and an unlocked position, wherein the lock arm comprises a tension mount at a tension end and the latch arm further comprises a tension mount disposed between the latch hook and the pivot end;
• a cam actuator structured to drive the lock arm between the locked position and the unlocked position and further structured to drive the latch arm from the latched position to the unlatched position;
• and
• a tension mechanism connected between the tension mount of the latch arm and the tension mount of the lock arm, wherein the lock arm is biased toward the locked position in response to the tension mechanism application of tension between the tension mount of the latch arm and the tension mount of the lock arm.

A platen latch assembly comprising:

• a latch arm defining a latch hook and a pivot end, wherein the latch arm is configured to rotate between a latched position and an unlatched position;
• a lock arm slideably coupled to translate along the latch arm between a locked and an unlocked position;
• and
• a cam actuator structured to drive the lock arm between the locked position and the unlocked position and further structured to drive the latch arm from the latched position to the unlatched position, wherein the cam actuator comprises a rack and pinion.
