Abstract: An apparatus comprises a dryer to force air onto a printed media during use to dry the printed media, and an air collector comprising at least one suction opening throughout which, in use, air from the dryer is collected. The apparatus may guide the collected air back to the dryer. The at least one suction opening may be arranged so as to stop the printed media from rising due to pressure differential.

Abstract: Disclosed are a printing device, a system and a method for printing medium feed. A device may comprise a support member and multiple rollers. The support member may support a print medium. The multiple rollers may each advance the print medium from the support member in an advance direction. The multiple rollers are arranged in a distributed manner along a width direction. The multiple rollers are operable in a disengage state detached from the print medium and the support member and in an engage state of pressing against the support member such to rest on the print medium or, if the print medium does not extend therebetween, to rest on the support member. The multiple rollers in the engage state are individually movable toward the support member.

Abstract: A printing system comprises an air-transmissive platen, a vacuum source, a cap and a controller. The vacuum source is configured to draw air through the platen to bias print media towards the platen. The cap is provided on a surface of the platen, between the vacuum source and the platen. The cap is configured to limit air flow through the platen, and comprises a plurality of closable openings provided in a plurality of zones along a length of the cap in a print media advance direction. The controller is configured to selectively open or close the openings of each of the plurality of zones to permit airflow through a portion of the platen overlain by print media and limit airflow through a portion of the platen not overlain by print media.
