ABSTRACT:
In a printing control apparatus in a page printer for making prints based on print data supplied from an external unit page by page, when the page printer is in an idling state, the print data is directly converted into dot image information. When the page printer is not in the idling state, the print data is converted into descriptors while the prior page print is being formed, and the descriptors are converted into dot image information. A print is made based on the dot image information. The printing control apparatus further includes a first jam recovery block for recovering a print corresponding to a jammed paper in the page printer by using descriptors in a case where the descriptors have been stored in a page descriptor area of a memory, and a second jam recovery block for recovering a print corresponding to a jammed paper in the page printer by using dot image information which has been stored in a bit map area of the memory.
