Abstract
An apparatus to detect toner consumption converts an original file into a spool file to perform preview before printing, converts the spool file into preview data, classifies objects based on types of items recorded in the spool file to create an object map, and calculates dot counts based on the preview data and information of the object map to detect toner consumption.
Claims22
A detection apparatus of toner consumption comprising:
- an enhanced meta file (EMF) creation unit to convert an original file into an EMF so as to perform preview before printing an image of the original file;
- a preview data creation unit to convert the EMF into preview data;
- an object map creation unit to classify objects in the EMF to create an object map;
- and
- a dot count calculation unit to calculate dot counts of pixels based on RGB values of the preview data and object attributes from the object map so as to detect toner consumption.

A detection method of toner consumption comprising:
- converting an original file into a spool file to perform preview before printing and storing the spool file;
- converting the spool file into preview data;
- classifying objects based on types of items recorded in the spool file to create an object map;
- and
- calculating dot counts based on the preview data and information of the object map to detect toner consumption.
2 more elements
A method of determining toner consumption, the method comprising:
- classifying objects of an enhanced meta file (EMF) into a plurality of object types;
- and
- applying different dot count data to each object type to generate dot count information of the EMF.
