| 1. A printing apparatus that prints, by applying a printing agent to a printing medium, an image on the basis of data developed
from object information, the object information being arranged based on layout information onto the printing medium, the layout
information indicating a layout and size of the object information, said apparatus comprising:
calculation means for analyzing the layout information to calculate a printing area in which the image is to be printed, said
calculation means calculating the printing area based on the layout and size of the object information indicated by the layout
information without using the data developed from the object information; and
prediction means for predicting, based on the printing area calculated by said calculation means, the usage of the printing
agent required for printing the image, wherein
said calculation means calculates the printing area in which a plurality of pieces of object information are arranged based
on the layout information, and
said prediction means predicts, based on the printing area calculated by said calculation means, the usage of the printing
agent required for printing the printing area in which the plurality of pieces of the object information are arranged.
