Abstract: A recording apparatus includes: a feeding unit which feeds a recording medium in a feeding direction; a recording head which discharges ink onto the recording medium for recording; and a first cleaning unit which performs first cleaning on at least one of a side surface on an upstream side of the feeding direction in the recording head, a side surface on a downstream side thereof, and side surfaces on both sides of a width direction of the recording medium with respect to the feeding direction.

Abstract: A recording apparatus has a recording head, a platen, and a first hole. The recording head includes a dot formation element array, and the platen holds a recording medium opposite the recording head. The first hole is disposed in an area of the platen opposite a downstream portion of the dot formation element array and guides ink discarded outside an end of the recording medium when the end is printed without a margin. Alternatively or additionally, a second hole is formed in an area of the platen opposite an upstream portion of the dot formation element array, and the platen guides ink, which is discarded outside an end of the recording medium when the end is printed without a margin, to the second hole.

Abstract: A printer 1 has an I/F section 31 for receiving data from a PC 2, a parameter-deriving section 35b for deriving a control constant on the basis of print setting information included in the received data, and a printer section 11 which performs printing operation on the basis of the print setting information, the control constant, and print data included in the received data.

Abstract: A rolled medium holding device includes a first gear mechanism 61 that is connected to a roll shaft holding the rolled medium and sends-out/rewinds the rolled medium, a second gear mechanism 62 that is connected to a torque limiter 64 and includes a plurality of torque transmission means, and a gear switching mechanism 63 that shifts connection between the plurality of torque transmission means and the first gear mechanism by operating the second gear mechanism for applying different back tension to the roll shaft.
