An image forming apparatus includes an image forming device, a base, circuitry, and a detector. The image forming device includes a recording head to form an image on a recording medium conveyed in a conveyance direction. The base supports the recording medium and is movable in the conveyance direction. A type of the base is changeable according to a type of the recording medium. The circuitry sets a detection range in the conveyance direction. The detector detects, before the image is formed, a collision between the recording head and the recording medium on the base, in the detection range set by the circuitry.

Image forming apparatus and image forming method

A liquid discharge method includes: calculating a first print time to print original image data on a print medium; generating rotated image data by rotating the original image data by a predetermined angle; calculating a second print time to print the rotated image data on the print medium; comparing the first print time and the second print time to determine whether the first print time is larger than the second print time; generating print image data according to the rotated image data in response to a determination in which the first print time is larger than the second print time; generating print image data according to the original image data in response to a determination in which the first print time is smaller than the second print time; and displaying a position and a direction of the print medium based on the print image data.

Liquid discharge method, non-transitory recording medium, and liquid discharge apparatus

A printing target holder includes a platen to hold a printing target portion of a printing target to which printing is applied, and the platen is configured to hold the printing target in a flat state. The platen includes a support face disposed on a top side of the platen and configured to support the printing target portion of the printing target; and an escape portion lower in height than the support face.

Printing target holder, printer, heater, image forming system, and recording medium

An image forming apparatus includes a computing unit to compute an amount of ink to be used to record raster data if a remaining amount of ink reaches a predetermined amount, and a recording control part to enable the recording if the remaining amount of ink is greater than the amount of ink computed by the computing unit. The recording control part disables the recording if the remaining amount of ink is less than or equal to the amount of ink computed by the computing unit.
