Abstract
An information processing apparatus includes at least one memory device that stores a set of instructions, and at least one processor that executes the set of instructions. The set of instructions includes instructions to acquire color data from an application, set a generation method for generating gray image data from color data by selecting a method from a group including at least a first generation method and a second generation method different from the first generation method, generate PDL data of gray image data based on the acquired color data and the set generation method, and transmit the generated PDL data to a printing apparatus.
Claims18
A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method, the method comprising:
- inputting color data;
- displaying a print setting screen for receiving a print setting;
- and
- receiving selection of a print mode from among a plurality of print modes including a color print mode and a grayscale print mode on the displayed print setting screen,
- wherein, in a state that the grayscale print mode is selected, a predetermined setting for using a conversion method in which the input color data is converted into grayscale data while assigning, based on the number of colors used in a page of the input color data, different achromatic values to the colors used in the color data is enabled, and
- wherein, in a state that the color print mode is selected, the predetermined setting is not enabled.
An information processing apparatus, comprising:
- one or more controllers including one or more processors and one or more memories, the one or more controllers configured to:
- input color data;
- display on a display a print setting screen for receiving a print setting;
- and
- receive selection of a print mode from among a plurality of print modes including a color print mode and a grayscale print mode on the displayed print setting screen,
- wherein, in a state that the grayscale print mode is selected, a predetermined setting for using a conversion method in which the input color data is converted into grayscale data while assigning, based on the number of colors used in a page of the input color data, different achromatic values to the colors used in the color data is enabled, and
- wherein, in a state that the color print mode is selected, the predetermined setting is not enabled.
