An inkjet printer for preventing ink flow, color blurring and color mixing during multicolor printing when image formation is performed with aqueous ink on a web-shaped printing base material, and an inkjet printing method using the inkjet printer. The inkjet printer is configured to perform image formation by discharging aqueous ink to a web-shaped printing base material, and includes: a conveyance mechanism configured to continuously convey the web-shaped printing base material; a single-pass system inkjet head configured to discharge the aqueous ink to a surface of the web-shaped printing base material conveyed by the conveyance mechanism; and a surface pre-heating unit arranged on an upstream side of conveyance from the single-pass system inkjet head and configured to heat at least the surface of the web-shaped printing base material. Image formation is performed on the web-shaped printing base material heated by the surface pre-heating unit.

An image recording apparatus includes an operation panel, a sheet conveyor, a print head, a cutting device, and a sheet discharge port. The operation panel is disposed at a first-side face of a housing in a particular direction that extends from a first side to a second side of the image recording apparatus. The sheet conveyor is configured to convey a sheet along a conveyance path in a conveyance direction. The print head is disposed downstream of the sheet conveyor in the conveyance direction. The cutting device has a cutter for cutting the sheet. The sheet discharge port is open at the first-side face of the housing. At least a part of the sheet passes through the sheet discharge port when the sheet is discharged from the conveyance path. The cutter positioned below the operation panel is exposed to an outside of the housing through the sheet discharge port.

A roll holder is for a label roll of linerless labels wound in a crosswise manner. The roll holder has: a horizontally arranged spindle, which is held by a stand on at least one side, and a rotatable roll mount, which is oriented in parallel with the spindle, and which is mounted on the spindle. The roll mount is mounted on the spindle in a linearly displaceable manner using at least one linear bearing.

A sheet feeding device includes a support that detachably supports a roll, a rotation driver that rotates a spool, a guide including a facing portion and a guide portion, a support shaft that swingably supports the guide, a biasing member that presses the guide, a sensor that retractably projects from the facing portion and outputs a detection signal, a roller that contacts an outer circumferential surface of the roll, and circuitry that controls the rotation driver. The circuitry determines a passing time based on a first change rate and a second change rate, and causes the rotation driver to rotate the spool by a predetermined angle in a winding direction, from the passing time, to position a leading end of a continuous sheet at a feeding start position, and rotates the spool in the feeding direction to feed the continuous sheet from the feeding start position along the guide portion.
