  • Patent number: 10313561
    Abstract: A target file includes: object data including pixels indicative of coordinate values in a first color space; and an input-side profile including data for converting coordinate values from the first color space into a specific color space. A color conversion is executed onto object data to generate post-conversion data including pixels indicative of coordinate values in a second color space. The executing color conversion includes executing judgment to judge, based on the input-side profile, which of first type post-conversion data generated through first type conversion using the input-side profile and an output-side profile, and second type post-conversion data generated through second-type conversion using prescribed data, should be used to output an image of the target file. The prescribed data is for conversion from the first color space into the second color space. The output-side profile contains data for conversion from the specific color space into the second color space.

  • Patent number: 10310448
    Abstract: In a case where a new consumable item is determined to be installed in a printer as a replacement for the current consumable item based on the related information, the printer receives, from the server, a first code assigned to a first consumable item to be installed in the printer. The printer obtains, from the second consumable item, a second code associated with a second consumable item installed in the printer as a replacement for the current consumable item. The printer determines whether the first code corresponds to the second code. The printer provides a notification indicating whether the second consumable item was determined to replace the current consumable item based on whether the first code corresponds to the second code.
