A modular camera and printer is disclosed. A camera module is provided having an image sensor for capturing an image in a RGB format. The camera module also has a central processing unit with program memory for storing program steps for execution by the central processing unit to operate the camera module, and an image storage memory for storing the captured image in the RGB format. An image processing unit of the camera module is in communication with the image storage memory and transforms image data in the image storage memory into a L*a*b* format. The camera module also has a serial bus for outputting transformed image data in the L*a*b* format. A printer module is provided also having a serial bus in communication with the serial bus of the camera module. The printer module receives the image data from the camera module in the L*a*b* format, converts the image data to a color space of the printer module, and then prints the image data on a printhead.

A method of generating half tone print data is disclosed. The method starts by determining an extent of overlap caused by temperature variations of overlapping end portions of a pair of consecutive printhead segments. A dither value is also generated from a dither matrix, and the dither value is combined with the extent of overlap to produce an output value. A mathematical operation is performed on continuous tone print data based on the output value, to produce the half tone print data.

A printhead having at least first and second rows of print nozzle cells. Each each nozzle cell has an ink chamber, control circuitry and drive circuitry. Each nozzle cell in the first row has a corresponding nozzle cell in the second row. The drive circuitry of each nozzle cell of the first row is arranged adjacent the drive circuitry of the corresponding nozzle cell in the second row and distant the control circuitry of the corresponding nozzle cell in the first row.

A printer system includes a printer and a printing consumable detachably mounted on the printer. The printer has a first integrated circuit which generates a random number, reference information using the random number and a secret key. The printing consumable has a second integrated circuit which generates validation information using the random number and the secret key received from the first integrated circuit. The printer also has processing circuitry configured for receiving the reference information from the first integrated circuit; receiving the validation information from the second integrated circuit; and comparing the reference information and validation information so as to validate the printing consumable device for use with the printer.

An inkjet printer includes a printhead assembly for ejecting ink upon print media; a capping molding for engaging a face of the printhead assembly; and an actuator for actuating the capping molding against and away from the printhead assembly. The actuator includes a flexible arm attached at one end to the capping molding and at the other end to slip and drive wheels. The slip and drive wheels facilitating actuation of the capping molding via the flexible arm. The flexible arm facilitates conformation of the capping molding against the printhead assembly.

A method of performing an action is disclosed. The method starts by sensing a print medium to obtain data encoded on a surface of the print medium. The data encodes at least a print media identifier. The print medium has a representation of a document printed thereon. The print media identifier is determined from the data and a digital copy of the document corresponding to the representation is retrieved. The digital copy is associated with the print media identifier and includes one or more hyperlinks. The digital copy of the document is displayed and a selection of one of the hyperlinks is received from a user. A predefined action designated by the selected hyperlink is then performed.
