A drive transmission device includes a rotatable driving member; a rotatable follower member, and an elastic member. The drive transmission device includes a first rotatable member and a second rotatable member. The first rotatable member includes first and second driving portions and a limiting portion. The second rotatable member includes a first driven portion, a second driven portion and a contact portion contacting the limiting portion. The second driving portion is adjacent to the limiting portion with respect to a rotational axis direction of the first rotatable member. The second driven portion is adjacent to the contact portion with respect to a rotational direction of the second rotatable member.

A printer may include a printhead assembly, a clutch assembly, and/or a printer ribbon transport assembly. An example clutch assembly includes a first spool engagement member defining a first friction torque; a first friction member configured to frictionally engage the first spool engagement member; a second spool engagement member defining a second friction torque that is larger than the first fiction torque; and a second friction member configured to frictionally engage the second spool engagement member.
