摘要： A physical layer which depends on hardware of a general-purpose interface determines whether an image supply device supports a predetermined communication protocol. A transport layer which controls communication as an upper layer of the physical layer determines whether the image supply device supports the predetermined communication protocol. When either of the physical and transport layers determines that the image supply device supports the predetermined communication protocol, the image supply device is decided to support the predetermined communication protocol. When both of the physical and transport layers do not determine that the image supply device supports the predetermined communication protocol, an application layer serving as an upper layer of the transport layer determines whether the image supply device supports the predetermined communication protocol.

摘要： Image processing apparatus and image processing method for formation of high quality image by high-speed error diffusion processing by execution of more complicated threshold condition processing in a simple manner. When error diffusion processing is performed on multivalued image data having plural density components and the result of processing is outputted, upon execution of error diffusion processing on a first density component among the plural density components, a threshold value used in the error diffusion processing is determined based on a density value of a second density component, then the error diffusion processing is performed on the first density component based on the determined threshold value, and the result of execution of the error diffusion processing is outputted. Further, upon execution of the error diffusion processing on the second density component among the plural density components, a threshold value used in the error diffusion processing is determined based on a density value of the first density component, then the error diffusion processing is performed on the second density component based on the determined threshold value, and the result of the error diffusion processing is outputted.

摘要： When the function of a printer has been changed, the printer notifies a DSC of a change in printer function using a capabilityChanged tag. If the DSC does not return any inquiry about the capabilityChanged tag, the printer determines that the DSC has no function that supports the capabilityChanged tag. The printer executes disconnection and re-connection of USB to execute a communication procedure with the DSC from the beginning, thereby notifying the DSC of the latest capability information in the printer.

摘要： A paper feed operation is performed by a width less than one pixel (½) in addition to an integer multiple number of pixels (n/2) with respect to a basic number of pixels inherent to an ink jet recording apparatus having a multi nozzle head having n nozzles. When a plurality of pixel recording operations are performed for a single pixel region, ink dots land within a distance less than one pixel unit (½). Thus, a variation in ink surface density on a recording sheet in an overlapping print operation is reduced, thereby efficiently increasing the image density, and preventing blurring by promoting absorption and evaporation of an ink to and from a paper sheet.

摘要： Improved techniques for measuring misalignment between multiple print heads, or between forward and reverse printing for the same print head. Adverse effects of ink bleeding, paper cockling and other ink ejection effects are reduced by superimposingly printed alignment patterns in which less than all pixels of printed portions of the patterns are filled in. Carriage ringing and overshoot effects are reduced by printing the alignment patterns in multiple passes, and preferably with an offset in carriage starting location for each pass. Improved detection of darkest density regions of the superimposingly printed alignment pattern is obtained through detections based on differences between densities rather than absolute values of measured densities.
