Method for controlling the sampling direction, sequence and position of color data in a frame memory in a color video line printer
 A printing control method for a video color printer includes the steps of: changing sampling direction so that a line memory inputs column samples among one frame data of a frame memory whenever printing is completed; sequentially designating one column sample position from left to right or vice versa according to the direction designated in the sampling direction changing step whenever one frame data is read out from said frame memory; and designating the position of unit samples so that said line memory sequentially inputs the column samples designated in the column sample designating step whenever one horizontal scan line data is read out. The method is advantageous in preventing paper's curl and dislocation of color by controlling an enabling signal of the line memory in a video color printer to allow reciprocative printing.
