  • Patent number: 6847470
    Abstract: A printing control device of the present invention is provided for a digital complex system having an automatic color sensing function and an interleaving print function. In the printing control device, a receiving unit receives a print request. A detection unit detects that a preceding printing task is active when the print request is received. An interleave printing control unit controls the interleaving print function such that, when a print mode of the received print request is different from a print mode of the active preceding printing task, execution of the interleaving print function is inhibited, and only when the print mode of the received print request is the same as the print mode of the active preceding printing task, the execution of the interleaving print operation is allowed.

  • Patent number: 6842264
    Abstract: A printer that contains printer devices that use different versions of a protocol is configured with a translation layer in printer firmware that receives one version of a protocol command from a sending device, translates the protocol command to another version of the protocol command, and sends the translated command to a receiving device or devices. The translation layer includes a table of modified commands that identifies each command used in the versions of the protocol used by the printer devices. The table of modified commands is used to generate a translation table for each device. The translation table is used to find a command that is compatible with a receiving device when the receiving device uses a different version of the command than the sending device. If the command has not changed in the protocol versions used by the sending and receiving devices, then the translation facility is not invoked and print processing proceeds normally.

  • Patent number: 6833930
    Abstract: When an original image is to be printed as a poster composed of an-array of 4×4 output images, an image is generated by enlarging the original image fourfold in the vertical and horizontal directions and dividing the enlarged image into 16 parts. These 16 partial images are output successively starting from the upper left or lower right of the 4×4 array, depending upon the designation. If there is a blank page, the blank page is output as is even if the printer possesses a blank-paper economizing function. Thus, when a poster printing function is used, the user designates the manner in which the enlarged image is divided up and the order in which the divided images are printed. Even if the printer is equipped with the blank-paper economizing function, normal printed results can be obtained merely by joining the output sheets together in the order that conforms to the manner in which the enlarged image was divided.

  • Patent number: 6804026
    Abstract: A color conversion method and apparatus for a compact printer system. An image processor converts a stored image from a first tri-color space to a second tri-color space. Resultant transformation values are read from lookup tables for each color component of the stored image pixels and a single cycle interpolator unit performs linear interpolation to generate a single color component in the second tri-color space in 14 cycles. In one example, the L*a*b* color space is converted to CMY color space. In another example, the RGB form is converted to the L*a*b* form and two extra L* components for use in sharpening a converted image.

  • Patent number: 6795203
    Abstract: An adjustment door (22) is provided on a housing (2) at an initial position of a carriage (3) on a side opposite to an original table (1). Accordingly, when printing medium powdery dust, dispersed ink or the like adheres to surfaces adjacent to a white reference (9) or a starting point (1a) for a scanner (20), it can be easily removed through the adjustment door (22). Since the gap between the original table (1) and the adjustment door (22) corresponds to the initial position of the carriage (3), a space for accommodating the carriage (3) at the initial position is not required at the end portion of the housing (2), and thus the size of an image input/output apparatus (100) can be reduced and the space required for it's installation can be easily obtained. Further, since a transparent detachable partition member (32) is detachably attached to a frame member (33), a printing medium jam in a printer (50) can be easily eliminated by removing the detachable partition wall (32) from the frame member (33).

  • Patent number: 6788427
    Abstract: An object of the present invention is to provide a print data controlling method for correctly performing, even when a print request regarding the same or similar print data is repeatedly issued, a print procedure desired by a user without decrease in printer operating efficiency and waste of resources such as paper. As a decision result produced by a print server on the basis of a comparison of data specifying information contained in print requesting data with data specifying information attached to each print data spooled in a print queue, a terminal device receives decision data which informs that there has already been spooled print data identical with or similar to print data regarding a current print request. Then, the terminal device will accept designation input for designating a print data processing procedure, thereafter sending to the print server processing data representative of contents of the designated print data processing procedure.

  • Patent number: 6788429
    Abstract: A method for managing a print queue over a computer network. The network generally includes at least one user interface, a network server, and at least one print server. The user interface uses a web browser or other mechanism to allow a user to communicate with the network server and the print server. Initially, the user directs the web browser to the network server and chooses a print server. The network server, using device management software, identifies the operating system of the print server and selects a print manager compatible with that operating system. The network server then installs and executes the selected print manager on the print server. Finally, the network server redirects the web browser on the user interface to the print manager on the print server allowing the user to manage a print queue for the print server.

  • Patent number: 6778294
    Abstract: A color printer receives N-bit values indicating a computer generated color to be printed. Each N-bit value has a most significant bit (MSB). Upon receiving the N-bit color values, the color printer creates an address from combined multiple-bit segments of each of the received N-bit values, each multiple bit segment includes at least a MSB of each N-bit value. The color printer includes a cache memory, each cache address including first and second entries. The first entry being values indicative of a computer generated color and the second entry being values usable by the color printer to reproduce a color indicated by the first entry. A processor determines if there is a match at an address created from a received computer color value between the first entry and the received computer color value. The processor is responsive to a determined match to access the second entry at the address and to employ the second entry to control the color printer.
