摘要： A printing apparatus arranged to perform printing while a monochrome printing head and a color printing head are moved in a direction in which the two heads are moved, the printing apparatus being arranged to print a plurality of patterns in which the relative quantity of deviation of printing timings of the two heads is changed in a stepped manner to cause a user to select a pattern having the smallest quantity of deviation among the plural patterns. Then, the selected pattern is used as a central value when a plurality of patterns in which the relative quantity of deviation of the printing timings of the two heads is changed in a stepped manner are furthermore printed to cause the user to select a pattern having a smallest quantity of deviation from the plural patterns. The above-mentioned process is repeated as necessary. As a result, the operation which is performed by the user to adjust the printing position can simply and easily be performed. Control is performed in such a manner as to change color to be printed by the color printing head whenever an adjustment mode in which the relative quantity of deviation of the printing timing is adjusted is started.
