By these steps, it becomes possible to design the process for causing the NC machine employing end mills as a cutting tool to perform a predetermined machining of a workpiece without relying on the experience of the designer, and without necessitating complicated work.

Abstract: In a printing apparatus which prints by serial scanning, a control command and image data formed from a plurality of rasters as a unit that are received from a connected host apparatus are stored in a reception buffer. Whether to perform marginless printing of printing on the entire surface of a printing medium is determined on the basis of information on the size of image data and information on the size of the printing medium that are contained in the control command.

Abstract: Disclosed is a portable, hand-held printing apparatus capable of maintaining high printing quality even when the movement of the apparatus becomes unstable due to looseness or wrinkles of a printing medium or even when the moving velocity of the apparatus changes. When a user moves the housing of this apparatus on a printing medium to print on the printing medium by using a printhead, the apparatus itself detects the moving velocity of the housing. On the basis of this detection result, the apparatus adjusts the supply timing of a driving signal for driving the printhead.
