The printing control apparatus compares, when printing a bit image, a data set of a transmitted compressed image data to a data set of an untransmitted compressed image data, omits transmission of the data set in the subsequent compressed image data when the data sets coincide with each other, and notifies the printing apparatus that transmission of the data set has been omitted with setting in a printing command. The printing apparatus holds the compressed image data in which the data set has been omitted, and, when it is notified that transmission of the part of the data set has been omitted, generates the bit image by reusing a part of the already existing data set and developing the held compressed image data.

Printing system, printing control apparatus, printing apparatus and method for generating a band compressed image data and print command includes selection of omitting untransmitted data set
