摘要： A tank unit is configured to introduce liquid supplied from a container and to lead out liquid toward a head configured to eject the liquid. The tank unit includes a storage section that stores the liquid supplied from the container, an introduction section that introduces the liquid supplied from the container into the storage section, an atmosphere opening section configured to open inside of the storage section to atmosphere, and an outlet section that leads out the liquid stored in the storage section. The introduction section is connected to the storage section, extends in a vertical direction in the storage section, and has an open end located within the storage section. The storage section includes a blocking section including a first protruding section located at a position in the vertical direction facing the open end and a second protruding section extending upward from the first protruding section.

摘要： An inkjet printer composes a first dot group including a first base dot group from ink dots of a first ink, and a second dot group including a second base dot group and a second additional dot group from ink dots of a second ink having a weaker color developing capability than the first ink. A total proportion of the first dot group with respect to the ink dots of the first ink is set to be a first print coverage greater than or equal to 100%. A total proportion of the second dot group with respect to the ink dots of the second ink is set to be a second print coverage greater than the first print coverage. Ink dots including the second additional dot group form a first print layer, and ink dots including the first base dot group and the second base dot group form a second print layer over or under the first print layer.

摘要： The present disclosure is directed to a microfluidic die that includes ejection circuitry and one time programmable memory with a minimal number of contact pads to external devices. The die includes a relatively large number of nozzles and a relatively small number of contact pads. The die includes decoding circuitry that utilizes the small number of contact pads to control the drive and ejection of the nozzles and the reading/writing of the memory with the same contact pads.

摘要： A control device for controlling a printer includes a conveyer and a print head. The control device performs: acquiring first image data representing a first image and second image data representing a second image; determining, based on the first image, a plurality of head positions of the print head relative to the first image; and determining a relative position of the second image relative to the first image such that, when the number of partial printings for printing the first image and the second image is increased from the number of partial printings for printing the first image, the relative position can minimize the increment.

The storage unit includes a print media catalog including a list of print media, each print medium in the list having a plurality of media attribute values characterizing the print medium, and each print medium categorized in at least one group based on at least one media attribute value. The print unit includes a print head for ejecting marking material on a print medium of the list. The control unit is configured to control the printing on a print medium of the list according to a plurality of optimization parameters, an optimization parameter being related to the at least one media attribute value used for categorization in a group of the at least one group. Upon receipt of a value of a particular optimization parameter for a print medium categorized in a particular group of the at least one group, the received value is automatically propagated to other print media categorized in the same particular group. A method is suitable for application in the printing system.
