A printing device executes processes (a)-(c). In the process (a), first and second rollers convey a sheet a first amount, and a print head executes a printing operation while the sheet is in a state where the sheet is supported by the first and second rollers and a supporting unit disposed between the first and second rollers. In the process (b), the second roller conveys the sheet a second amount that is no larger than the first amount, and the print head executes a printing operation while the sheet is in a state where the sheet is supported by the supporting unit and the second roller. In the process (c), the second roller conveys the sheet a third amount that is larger than the first amount, and the print head executes a printing operation while the sheet is in a state where the sheet is supported by the second roller.

A system for shaping media for printing by a media width printhead is provided having a media width printhead of fluid ejection nozzles defining a media width print zone, input rollers disposed for transporting media into the print zone at an angle to a plane parallel with the print zone, output rollers for transporting media out of the print zone at an angle to a plane parallel with the print zone, and an elongate platen for supporting and shaping the media as the media is transported through the print zone. The platen has a series of ribs disposed upstream of the print zone and a series of ribs disposed downstream of the print zone. The ribs are configured so that the transported media adopts a constrained curved path past the nozzles through contact with the ribs in the print zone.

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.
