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 height adjustment apparatus for a print carriage comprises a support for supporting the print carriage and a moving mechanism. The support has an upper support surface configured to slidingly engage a surface of the print carriage. The height of the support surface in a first direction increases in a second direction, perpendicular to the first direction. The moving mechanism is configured to move the support in the second direction, wherein when the support is moved in the second direction, the print carriage surface is configured to slide relative to the support surface to move the print carriage in the first direction.
