In some examples, a non-transitory-machine readable medium can store instructions executable by a processing resource to select a special media mode from a plurality of special media modes based on a weight or a type of print media and cause a conditioning device to condition the print media in accordance with the special media mode.

A printing apparatus includes a liquid ejecting unit capable of ejecting ink, which is a liquid, onto a medium and capable of reciprocating in a width direction (X-axis direction) of the medium, a medium support unit that supports the medium on a support face, a medium width detection unit that detects a width of the medium supported on the support face, a plurality of heating units that are provided along the width direction of the medium and heat the medium support unit, and a control unit capable of individually controlling the plurality of heating units. The control unit controls an output of each of the heating units in accordance with the width of the medium detected by the medium width detection unit.

A recording unit which is provided in a recording system includes a heat roller pair which contacts paper and performs drying of the paper after recording by a line head using heating and a control unit which controls operation of the heat roller pair, in which a heating region of the heat roller pair is divided into a plurality of subdivisions in a width direction which intersects the medium transport direction and the heat roller pair is configured to be capable of modifying a heating state for each subdivision region, and in which the control unit controls the heating state of each of the subdivision regions in the heat roller pair according to conditions when performing drying of the paper using the heat roller pair.

A first unit includes a receiving portion that receives a medium to be processed, a drying unit that processes the medium received from the receiving portion, and an end stitching unit that processes the medium received from the receiving portion or the medium processed by the drying unit. The processing performed by the drying unit is processing of drying the medium, the drying unit is located vertically below the end stitching unit, and the drying unit and the end stitching unit have a portion overlapping when viewed in a vertical direction.

Inkjet printing apparatus including: ink accommodating unit storing ink; ejection head configured to eject the ink to form print layer; and heating unit configured to heat print target, wherein the ink is clear ink including resin and water, dry film of the clear ink has glass transition temperature of 50° C. or more, the inkjet printing apparatus has first printing mode and second printing mode, and the heating unit is configured to heat the print target so that expression: T.sub.matte>T.sub.gloss is satisfied, where the T.sub.matte is temperature (° C.) of the print target in printing region printed in the first printing mode obtained when the clear ink is deposited on the print target, and the T.sub.gloss is temperature (° C.) of the print target in printing region printed in the second printing mode obtained when the clear ink is deposited on the print target.

An ink jet recording method includes a treatment liquid attachment step, in which a treatment liquid is attached to a recording medium, and an ink attachment step, in which a water-based ink composition is attached to the recording medium. An ink jet recording apparatus includes a recording medium support and a heating mechanism that heats the recording medium support. The ink attachment step is carried out with the recording medium supported and heated by the recording medium support. In the ink attachment step, the recording medium is heated so that a surface thereof reaches a maximum temperature of 28.0° C. or more and 45.0° C. or less. The ratio between absorbances A and B (A/B) is 0.5 or more and 0.95 or less, where absorbance A is that of a 0.1% by mass mixture of the water-based ink composition in the treatment liquid, and absorbance B is that of a 0.1% by mass mixture of the water-based ink composition in purified water.
