A printing control apparatus that facilitates settings, such as magnification-reduction and a layout of plural pages on one printing plane, and thereby improves the operatability. The operator sets in advance print attribute information, such as an orientation, a printable area, and magnification-reduction, mapped to plural pieces of logic sheet information with a data input device 5. The plural pieces of logic sheet information with the print attribute information mapped thereto are accordingly registered in a pull-down menu 47. The operator selects one piece of logic sheet information out of the pull-down menu 47, so as to set the print attribute information corresponding to the selected piece of logic sheet information. In the printing control apparatus, bit map data based on print data are edited according to these various pieces of information.
