Abstract: An autonomous traveling body includes a vehicle body, a mover, an obstacle detector, a traveling controller, and a storage. The mover causes the vehicle body to travel. The traveling controller controls the mover based on a detection result of the obstacle by the obstacle detector. The storage stores an obstacle detection area around the vehicle body. The obstacle detection area includes a stop area having a predetermined width with the traveling direction of the vehicle body as an axis, and first and second deceleration areas excluding the stop area. When at least a portion of the obstacle is included in the stop area, the traveling controller stops the vehicle body. When at least a portion of the obstacle is included in the first deceleration area or the second deceleration area, the traveling controller reduces the traveling speed of the vehicle body.

Abstract: Image data is acquired, it is determined whether the tone value specified by tone value information included in the acquired image data is equal to or greater than a predetermined tone value, and the tone value information is converted into a description that indicates a still smaller tone value if it is determined that the answer is negative.

Abstract: In a printing control method arranged to control a printer via a network by using a computer, stored print setting data is referred to when direct printing is specified, either one of original document data and print data in which the original document data is described in a page description language is selected as data to be transmitted to the printer, the original document data is transmitted to the printer when the original document data is selected, and the original document data is converted into the page description language and then transmitted to the printer when the print data is selected.
