Print controlling apparatus, image forming apparatus, and method for forming image

A print controlling apparatus usable with an image forming apparatus, the print controlling apparatus comprising:

• a user interface unit to receive a print command regarding a print job;
• an extraction unit to extract one or more graphical primitives from the print job;
• an image forming unit to form an image by arranging the one or more graphical primitives according to a determination of whether the extracted graphical primitives are disposed close to each other;
• a sketch image generation unit to convert the formed image into a sketch image;
• a print data generation unit to modify the print data by replacing the sketch image and a portion of the graphical primitives constituting the sketch image;
• and
• a communication interface unit to transmit the modified print data to the image forming apparatus.
