Abstract
A computer-readable recording medium stores a printer driver that causes a computer to function as: a PDL conversion unit configured to convert drawing data received from an application into PDL data; a rasterization unit configured to convert at least one of a text object and a vector object into a raster object when the drawing data is converted into the PDL data; and a communication control unit configured to transmit the PDL data to an image forming apparatus. Before-conversion information, that indicates a data format of the object before the conversion is associated with the converted raster object.
Claims14
A non-transitory computer-readable recording medium storing a printer driver, the printer driver causing a computer to function as:
- a page description language (PDL) conversion unit configured to convert drawing data received from an application into PDL data;
- a rasterization unit configured to convert an object into a raster object when the drawing data is converted into the PDL data, wherein the object is at least one of a text object and a vector object;
- and
- a communication control unit configured to transmit the PDL data to an image forming apparatus,
- wherein before-conversion information is attached as a comment to a front or a rear of the converted raster object, which indicates that a data format of the object before the conversion into a raster object is a text object or a vector object, and
- wherein the printer driver controls the image forming apparatus to reduce a number of gray levels of color information included in the object (i) if the transmitted PDL data is printed in color and (ii) if the before-conversion information is attached to the converted raster object.
A non-transitory computer-readable recording medium storing a printer driver, the printer driver causing a computer to function as:
- a PDL conversion unit configured to convert drawing data received from an application into PDL data;
- a rasterization unit configured to convert an object into a raster object when the drawing data is converted into the PDL data, wherein the object is at least one of a text object, a vector object, and a raster object;
- and
- a communication control unit configured to transmit the PDL data to an image forming apparatus,
- wherein before-and-after-conversion information is attached as a comment to the front or rear of the converted raster object, which indicates that a data format of the object before and after the conversion is the text object, the vector object, or the raster object, is associated with the raster object and,
- wherein the printer driver controls the image forming apparatus to reduce a number of gray levels of color information included in the object (i) if the transmitted PDL data is printed in color and (ii) if the before-conversion information indicates that the object is a text object or a vector object.
A printing method with a printer driver, the method comprising:
- converting drawing data received from an application into PDL data;
- converting an object into a raster object when the drawing data is converted into the PDL data, wherein the object is at least one of a text object and a vector object;
- attaching before-conversion information as a comment to the front or rear of the converted raster, which indicates that a data format of the object before the conversion into the raster object is a text object or a vector object;
- transmitting the PDL data to an image forming apparatus;
- and
- controlling the image forming apparatus to reduce a number of gray levels of color information included in the object (i) if the transmitted PDL data is printed in color and (ii) if the before-conversion information is attached to the converted raster object.
