A printing control apparatus includes a control unit. Provided that n is an integer equal to or greater than one, the control unit configured to perform printing control processing including a plurality of types of processing configured to be performed simultaneously is configured to, in the printing control processing performed for an n-th time, write, to a first storage medium of the storage unit, n-th print data that is the print data generated in the printing control processing performed for an n-th time, and, in the printing control processing performed for an n+1-th time, write, to a second storage medium of the storage unit, n+1-th print data that is the print data generated in the printing control processing performed for an n+1-th time, and also read the n-th print data from the first storage medium and supply the n-th print data to the printing unit.
