A tape cassette that includes a housing having a top surface, a bottom surface, a front wall, a tape feed exit on the front wall, and an arm portion formed by the front wall and an arm rear surface behind the front wall. The arm portion partially surrounds an opening, and a tape feed path passes through the arm portion. The tape cassette also includes a tape at least partially included within the housing and configured to be fed along the tape feed path extending to the tape feed exit, an ink ribbon at least partially included within the housing, a take-up spool included within the housing and configured to take-up the ink ribbon, and a first aperture formed on a bottom edge of the front wall. A virtual line orthogonal to the front wall intersects the first aperture, the opening, and the take-up spool.

A tape cassette that includes a housing having a front wall and a tape feed exit located on the front wall, a tape included at least partially within the housing, and a pressing portion and a first non-pressing portion on the front wall. The pressing portion and the first non-pressing portion are positioned to oppose tape type detecting switches of the label printer when the cassette is in the label printer. The pressing portion is configured to change a state of an opposing one of the tape type detecting switches, and the first non-pressing portion is configured to avoid changing a state of an opposing one of the tape type detecting switches. The first non-pressing portion is a planar area of the front wall extending in a tape width direction from a top surface of the housing to a bottom surface of the housing.

A tape cassette that includes a tape cassette that includes a housing having a top surface, a bottom surface, a rear wall, a front wall, and a tape feed exit located on the front wall, a tape included at least partially within the housing and configured to be fed along a tape feed path extending to the tape feed exit, and a first indicator aperture positioned on the front wall and a second indicator aperture position on a rear portion of the bottom surface. A position of the first indicator aperture on the front wall indicates a type of the tape included within the housing. A position of the second indicator aperture indicates a color of characters.

A printing device for printing on a label sheet includes a first print head to perform printing on a first side of a label sheet being conveyed along a conveyance path. The label sheet is interposed between the first print head and a first roller. A second print head is upstream of the first print head and performs printing on a second side of the label sheet. A second roller is adjacent the second print head across the conveyance path. A cutter is downstream of the first print head to cut off a first portion of the label sheet. A processor is configured to cause the label sheet to be conveyed in a second direction after the first portion is cut off from the sheet so that the cut end of the sheet reaches the first print head.

A tape cassette that includes a housing having a top surface, a bottom surface, a tape feed path, a front wall, and a tape feed exit adjacent to the front wall. The tape cassette also includes a tape configured to be fed along the tape feed path to the tape feed exit, an ink ribbon, and a take-up spool configured to take-up the ink ribbon and having an axis of rotation. A first aperture is formed on a bottom edge of the front wall, wherein a portion of the first aperture is downstream of a location at which a virtual line orthogonal to the front wall and passing through the axis of rotation of the take-up spool passes through the front wall and upstream of a virtual centerline that is orthogonal to the bottom surface and divides the front wall into left and right portions.
