Abstract
The present invention provides a method for controlling the movement of a print medium to be printed, for example, in a facsimile device. The invention uses printing velocities for each line (or printing unit) to be printed, which are calculated based on the number of black picture elements in the image signal related to this line (or picture unit). These calculated printing velocities are stored each for succeeding line to be printed and are then used to determine the moving velocity of the print medium for the actual line being printed.
