Abstract

Disclosed is a print controlling device including a control unit to control printing according to an instruction which relates to the printing, wherein the control unit analyzes a page description language which relates to the printing, determines whether the printing is practically monochrome printing or color printing, and changes a first command of the page description language to a second command for monochrome printing when it is determined that the printing is monochrome printing.

Claims

1. A print controlling device comprising:

a control unit to control printing according to an instruction which relates to the printing;

wherein the control unit;

analyzes a page description language which relates to the printing, and determines whether the printing is practically monochrome printing or color printing; and

changes a first command of the page description language to a second command for monochrome printing when it is determined that the printing is monochrome printing.

2. The print controlling device of claim 1, wherein the control unit does not conduct a following determination processing which relates to the printing when it is determined that the printing is color printing.

3. The print controlling device of claim 1, wherein the control unit determines whether the printing is practically monochrome printing or color printing for each page.

4. An image forming device comprising:

a receiving unit to receive an instruction which relates to printing;

a control unit to control the printing according to the instruction which relates to the printing received by the receiving unit; and

a printing unit to execute the printing according to a control from the control unit;

wherein the control unit;

analyzes a page description language which relates to the printing, and determines whether the printing is practically monochrome printing or color printing; and

changes a first command of the page description language to a second command for monochrome printing when it is determined that the printing is monochrome printing.

5. The image forming device of claim 4, wherein the control unit does not conduct a following determination processing which relates to the printing when it is determined that the printing is color printing.

6. The image forming device of claim 4, wherein the control unit determines whether the printing is practically monochrome printing or color printing for each page.

7. A print controlling method comprising:

analyzing a page description language which relates to a printing, and determining whether the printing is practically monochrome printing or color printing; and

changing a first command of the page description language to a second command for monochrome printing when it is determined that the printing is monochrome printing.

8. The print controlling method of claim 7, wherein a following determination processing which relates to the printing is not conducted when it is determined that the printing is color printing.

9. The print controlling method of claim 7, wherein determination whether the printing is practically monochrome printing or color printing is conducted for each page.

10. A computer readable recording medium that stores a control program which is executed by a control unit of a print controlling device that controls printing according to an instruction which relates to the printing, the control program causing the control unit execute:

analyzing a page description language which relates to the printing, and determining whether the printing is practically monochrome printing or color printing; and

changing a first command of the page description language to a second command for monochrome printing when it is determined that the printing is monochrome printing.

11. The computer readable recording medium of claim 10, wherein the control program does not cause the control unit execute a following determination processing which relates to the printing when it is determined that the printing is color printing.

12. The computer readable recording medium of claim 10, wherein the control program causes the control unit execute determination on whether the printing is practically monochrome printing or color printing for each page.
