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.
