摘要： If an optional paper feeding deck or furnisher, or paper stacker, is connected to an image forming apparatus (such as a printer), such optional devices are to be controlled by connecting the paper conveyance control apparatus to control those options. Such an image forming apparatus has a video controller to convert the printer language sent from a high-order device such as a host computer, into bit map data and a printer engine to print the bit map data. Such a paper conveyance control apparatus, being electrically connected to the video controller, has a memory to be shared with the video controller. The video controller writes the job schedule in the shared memory. The paper conveyance control apparatus controls the optional device according to the written job schedule.

摘要： Whether the number of prints is equal to or larger than a predetermined number or not is judged. Whether the total number of pages in a job is equal to an odd number or not is judged. When the total number of prints is equal to or larger than the predetermined number and when the total number of pages is equal to the odd number, the printer controller controls in a manner such that a final paper is fed by only a first feed and an image is printed to only the first side of the paper and the paper is ejected out. In the case where the total number of prints is less than the predetermined number and the total number of pages is equal to the odd number, the printer controller controls in a manner such that the final paper is fed by the first feed and an image is printed to the first side of the paper and, subsequently, the paper is fed by a second feed and an image is printed to a second side of the paper on the basis of blank page data and the paper is ejected out.

摘要： When an optional unit (40, 50) is mounted, a video controller (27) serving as main control unit sends various control commands to a supervising controller (101) through an interface (114). The supervising controller (101) controls an engine controller (26) through an interface (29) while controlling the optional unit (40, 50) in accordance with the received control commands, thereby recording an image. When no optional unit is mounted (when the optional units 32, 40, 50 are absent), the video controller (27) directly controls the engine controller (26) through an interface (28), thereby recording an image. With the above arrangement, the supervising controller (101) serving as a control unit associated with optional units can be attached/detached.

摘要： In a printer apparatus having an automatic paper feed selection function for automatically selecting one of a plurality of paper feed means in which a paper of a designated size is loaded, an operator is permitted to set a desired priority. When there are a plurality of paper feed means in which the paper of the designated size are loaded, the paper feed means of a higher priority is selected to cause the selected paper feed means to feed the paper for printing. The priority may be set to groups each comprising a plurality of paper feed means. When there are a plurality of paper feed means in one group in which the paper of the designated size are loaded, the paper is fed from predetermined paper feed means. When no paper is loaded in a paper feed cassette of the paper feed means from which the paper is to be fed, one of a plurality of operation modes relating to a timing to inform it may be selected by the operator.

摘要： An image forming system provided with a printer engine and a controller which communicates with the printer engine over a serial communication interface. The controller receives a condition change signal from the printer engine over a dedicated signal line, which is outputted by the printer when the condition of the printer engine changes. The identity of the condition that has changed is then communicated over the serial communication interface. Further, the controller designates one of a plurality of kinds of condition changes, in response to which the condition change signal is outputted, according to the conditions of the controller or the image forming system.

摘要： A half-tone image recorder in which input digital data is represented by a plurality of bit data for each pixel. A data conversion device outputs digital data indicative of a recording-start position and a recording-end position, based on the input digital data. A recording device such as a laser printer records an image in accordance with the output digital data from the data conversion device. The data conversion device controls a first value of the digital data indicative of the recording-start position and a second value of the digital data indicative of the recording-end position so as to change a black-area growing direction within one pixel in the recorded image. This results in the recordation of a high-quality half-tone image without conspicuous vertical stripes and without conspicuous white stripes in the main-scanning direction of the recording device due to pitch irregularity.

摘要： An image processing apparatus in which a density pattern is generated which corresponds to input image data. Growth direction of the density pattern is controlled by generating a density pattern in a prescribed direction, and generating a density pattern in a direction based on a random signal. As a result, when printing the image data based on the generated density patterns, there is no joining between adjacent pixels and a high-quality image is produced.
