Abstract
Disclosed is a method for processing graphic data in a laser printer capable of improving an effect of processing the graphic data, in which the graphic data are processed even though post-processing of the graphic data is not completed while pre-processing of the graphic data is performed. The method according to the present invention includes the steps of: processing low level graphic data which are inputted from a host computer to a laser printer to generate graphic elements; and generating and printing real bitmap image corresponding to a respective band on a recording paper during the feed of the recording paper after carrying out the pre-processing.
Claims20
A method, comprising:
- detecting end of page when graphic data are received at an image formation apparatus from a host computer;
- when end of page is detected, transmitting selected data to a post-processor unit;
- when end of page is not detected, processing said graphic data to generate graphic element data, said processing of said graphic data being performed by a pre-processor unit;
- processing said graphic element data to generate bitmap data corresponding to a respective band on a recordable medium during a transporting of the recordable medium along a path of conveyance in said image formation apparatus;
- and
- forming an image on the recordable medium corresponding to said bitmap data;
- said processing of said graphic element data to generate said bitmap data further comprising:
- generating said bitmap data corresponding to said respective band on the recordable medium when said respective band increases at start of a present page;
- when said bitmap data have been generated, detecting end of the present page, said detecting of end of the present page being performed by a graphic execution unit;
- and
- when end of the present page is detected, stopping said forming of said image on the recordable medium.

An apparatus, comprising:
- a pre-processor unit receiving graphic data from a host computer, said pre-processor unit detecting end of page when said graphic data are received, said pre-processor unit transmitting selected data when said end of page is detected, said pre-processor unit processing said graphic data to generate graphic element data when said end of page is not detected;
- and
- a post-processor unit receiving said selected data from said pre-processor unit and receiving said graphic element data from said pre-processor unit, said post-processor unit processing said graphic element data to generate bitmap data corresponding to a respective band on a recordable medium during a transporting of the recordable medium along a path of conveyance, said bitmap data being utilized to form an image on the recordable medium;
- said pre-processor unit performing said processing of said graphic element data by generating said bitmap data corresponding to said respective band on the recordable medium when said respective band increases at start of a present page, detecting end of the present page when said bitmap data have been generated, and stopping forming of said image on the recordable medium when end of the present page is detected.
