Abstract: An image processing apparatus includes a maximum/minimum density detecting unit which detects a center pixel of a matrix of N×N pixels in image data that has a maximum or minimum density. A determination unit determines whether the absolute value of a difference between an average of densities of diagonal pixels of the matrix and a density of the center pixel is larger than a threshold value. A peak pixel detecting unit detects peak pixels of the matrix, each peak pixel being the center pixel having a maximum or minimum density, and the absolute value of the difference with respect to the center pixel being larger than the threshold value. A dot region detecting unit detects one of neighboring pixels of the matrix as being a dot region based on the number of the peak pixels in a target region and the number of the peak pixels in each of neighboring regions.

Abstract: This invention relates to the printing of transparent media often used for later projection, commonly referred to as Over Head Transparencies, or OHT's. These OHTs are used in several ways: They can be printed in advance and projected in sequence, created in the course of the presentation using marking pens, or a combination of he two, where a pre-printed OHT is edited or modified after printing or in the course of presentation using pens or other marking means. This third use is often compromised by incompatibilities between the marking technology used to create the pre-printed image and the marking pens used to edit the image later. This invention describes a technique for separating the two images, placing each on opposite sides of the transparent film, avoiding this conflict and producing a better solution for the user.

Abstract: An area on the printing sheet which can be printed through a single scanning operation of a printing head is divided into a plurality of smaller areas. The printing sheet is transported a distance corresponding to each divided area to print the image using different nozzles of the printing head for each divided area. When a back end portion of the printing sheet is printed, the distance transported is reduced to set inoperative nozzles that are not used for the printing operation. Then, when the printing sheet slips out from the upstream roller pair and it is then detected that the printing sheet is to be transported a distance longer than predetermined amount of rotation of the roller, the inoperative nozzles are used to shift an operative nozzle range depending on the extra amount of rotation. Thus, the extra transportation of the printing sheet is corrected.

Abstract: One aspect of the invention checks mechanical misalignment of plural pens and shifts data to allow for at least part of misalignment—and automatically prints images with the shifted data. If pens are aligned within a dot row then preferably the image prints without data shift. In one other preference, the pens print respective ink types; in this regard a particular preference is that the inks include plural colors, or alternatively plural dilutions. The invention is particularly beneficial in printing on a particular printing medium that is insensitive to relative timing of deposition of ink types; in this case an ideal print medium is plain paper. In some such situations the data shift best compensates for only part of misalignment, and pen-nozzle selections for the rest. In other situations the shifting step best compensates for all the misalignment. In another aspect, the invention extends marking element life and thereby printhead life by distributing usage over a maximum number of elements.

Abstract: As it is often difficult for users of a keyboard to adequately identify and select the correct keys in a keyboard where the light is inadequate, it is desirable to provide a keyboard capable that allows a user to better see keys of the keyboard even in environments where there is not sufficient light to see the keys (e.g., in an airplane). A keyboard of the present invention comprises a substrate, a membrane, an elastic member, a cover sheet, a keytop, and light-emitting means for emitting light from the bottom of the substrate to the keytop. The keytop is illuminated and a legend on a key surface can be seen, so that the chance of incorrect key stroke is reduced.

Abstract: A process in which a scented ink is applied to an article. An oil-based scent is mixed with a plastisol-type ink and applied to an article, such as a t-shirt. All layers of the ink forming the design, including the base layer, the color layers and a top special effects clear plastisol ink, include the scent. The combination of a plastisol ink and the oil-based scent results in a design with a positive “hand”, where elevated temperatures activate the scent.

Abstract: There is provided a printing apparatus and method which is capable of printing based on internal data stored within the apparatus or external data inputted from an external storage device, and at the same time capable of setting the enabling/disabling of an automatic power-off function. A tape printing apparatus has a keyboard for entering data indicative of characters and various commands. A RAM stores the data entered via the keyboard, as the internal data. The external data stored in a personal computer is inputted into the tape printing apparatus via a cable. The printing mode is sets to either an internal printing mode in which printing is performed based on the internal data stored in the RAM or an external printing mode in which printing is performed based on the external data inputted from the personal computer via the cable. A printer block performs printing on a tape in the set printing mode. A CPU determines ON/OFF setting of an automatic power-off function of automatically turning off power.

Abstract: In an image forming apparatus mountable a detachable unit mounting a memory in a main body of the apparatus, a memory-access-reservation control unit for accepting a request of an access with respect to a nonvolatile memory provided in a process cartridge in which a photosensitive drum, a toner and the like are integrated is provided in an engine control unit.

Abstract: When a communications terminal has stopped operating because it is off-line, data received from a host is efficiently stored to a receive buffer so that receive buffer full states cannot easily occur. A data interpreter interprets the receive buffer content in the input order. An action buffer stores interpreted commands. A command execution controller executes commands in the action buffer in first-in first-out order. The data interpreter continues interpreting the received data even when operation of the command execution controller is stopped, and kills without storing to the action buffer any real-time commands detected by the data interpreter.

The printing apparatus including a printhead having a plurality of print elements and a head driver for generating a pulse-like driving signal supplied to the printhead. The apparatus sets driving conditions for a printhead with test patterns obtained by simultaneously driving a predetermined number of print elements of the plurality of print elements are printed on the printing medium while the pulse width of the driving signal is decreased stepwise from a predetermined value. Then, the boundary value of a pulse width with which a print element is not properly driven is obtained from the test patterns, and the pulse width of a driving signal generated by the head driver is controlled on the basis of the boundary value.
