A handheld recording device includes a first face, a second face, a third face pair, a recorder, and a connector. The first face has an opening. The second face is disposed opposite the first face. The third face pair is different from the first face and the second face. One of the third face pair is disposed on one side in a given direction of the second face and configured to be held by a user for recording. The recorder is configured to discharge ink from the opening. The connector is configured to be connected to a cable to receive at least one of power and image data. The connector is disposed at a position closer to the second face than the first face, on another one of the third face pair disposed on another side in the given direction of the second face.

Handheld recording device

A data generation system includes circuitry configured to generate data of sub-images constructing an image. Each of the sub-images includes at least one of image elements of the image. The image elements are aligned in a direction perpendicular to a given direction in which an image forming apparatus moves to form the image. The circuitry is configured to, when, in an attempt to add another one of the image elements adjacent to the at least one of the image elements in one of the sub-images, the other one of the image elements does not fit within the one of the sub-images, generate data of the one of the sub-images without the other one of the image elements.

A droplet discharge apparatus discharges a droplet to form an image on a recording medium while being moved by a user. The droplet discharge apparatus includes a head to discharge a droplet on a recording medium according to image data, a sensor to detect a movement amount of the droplet discharge apparatus in a predetermined period, and a processor. The processor is configured to instruct droplet discharge based on the image data and the movement amount detected by the sensor, determine floating of the droplet discharge apparatus from the recording medium based on information from the sensor, and stop the droplet discharge in response to a determination that the droplet discharge apparatus is floating.

Droplet discharge apparatus and droplet discharge method

A liquid droplet discharging apparatus includes a plurality of nozzles to discharge a liquid droplet onto a medium and a liquid droplet discharging controller to receive image data. The liquid droplet discharging controller controls each of the nozzles to discharge the liquid droplet in an amount defined by the image data onto a target discharging position on the medium, which corresponds to a pixel position defined by the image data. The liquid droplet discharging controller controls at least one of the nozzles to discharge the liquid droplet for a controlled number of times smaller than a number of times N representing an integer not smaller than 2 in an amount greater than the amount defined by the image data onto the target discharging position on the medium. A frequency recorder records the controlled number of times of discharging for each of the at least one of the nozzles.

A mobile image forming apparatus includes a body; a recording device supported by the body and configured to form an image on a recording medium, and at least one roller provided to the body and configured to rotate on the recording medium while the body is moved in a scanning direction for image formation. The mobile image forming apparatus further includes at least one pressing member disposed in contact with the at least one roller and configured to press the at least one roller in a roller axial direction.

A droplet discharge apparatus to discharge droplets while moved by a user includes a head to discharge a droplet onto a recording medium, a sensor to detect a movement amount of the droplet discharge apparatus in a predetermined period, and a memory to store determination information indicating whether droplet discharging has been instructed for each pixel of the image data. The droplet discharge apparatus further includes a processor configured to accumulate the movement amount to calculate a total movement amount of the droplet discharge apparatus; instruct droplet discharging from the head based on the total movement amount and the image data; instruct droplet discharging only for an unprinted pixel for which the determination information indicates that droplet discharging has not been instructed; and rewrite the determination information of the unprinted pixel to indicate that droplet discharging has been instructed, based on a predetermined condition.

A computer program for an information processing device communicating with a droplet discharging device is provided. The droplet discharging device is configured to form rendering data on a printing medium by being moved by a user on the printing medium, and includes a position calculation unit for calculating a position of the droplet discharging device, and a droplet discharging unit for discharging a droplet in accordance with the rendering data and location information. The computer program is configured to cause the information processing device to function as a scanning direction output unit for outputting a scanning direction of the droplet discharging device.
