摘要： An example disclosure printer includes a base assembly, a lid pivotably attached to the base assembly, and a ribbon frame pivotably connected to the base. The ribbon frame is configured to receive at least one ribbon spool; a ribbon locker configured to interact with the ribbon spool via a spool gear assembly, the ribbon locker comprising: a biasing element to maintain a biasing force on the ribbon locker in a first direction, a first pawl, a second pawl, and a central pivot, wherein: when the ribbon locker is rotated by the actuator in the first direction, the first pawl is brought into contact with the spool gear assembly, and when the ribbon locking assembly is rotated in a second direction opposite the first direction, the second pawl is brought into contact with the spool gear assembly.
