A cassette includes a printing tape roll being rotatable and into which a printing tape as a medium to be printed is wound, and an outer peripheral wall disposed on one side in a first direction relative to the printing tape roll. The first direction is a width direction of the printing tape. The outer peripheral wall includes a first side wall extending in a second direction orthogonal to the first direction, a second side wall extending in a third direction orthogonal to the first direction and intersecting with the second direction, and a recess wall defining a recess extending from the second side wall toward one side in the second direction. The recess extends in the third direction on one side in the second direction further than the second side wall. At least a portion of the recess overlaps the printing tape roll in the first direction.

A ribbon supply includes a supply spool and a ribbon material wound onto the supply spool. A tack down bond prevents unwinding of the ribbon material from the supply spool. A leader film extends from the tack down bond, with the leader film having a length that is sufficient to allow installation of the ribbon supply and connection of the leader film to a take-up spool without detaching the tack down bond.

A cassette includes: a case including a first layer and a second layer and having a head space at the first layer; and a roll disposed at the second layer and into which a medium to be printed is wound about a rotation axis in a winding direction. The medium to be printed includes a to-be-printed layer and a release layer, and is disposed at the case such that the to-be-printed layer is on an inner side thereof and the release layer is on an outer side thereof in the winding direction. The case has a conveyance path for conveying the medium to be printed. The conveyance path is defined such that the medium to be printed is conveyed in the winding direction from the roll to the head space through an opening defined at a boundary between the first layer and the second layer in the case.
