摘要:
A mechanism that attains high-speed processing by distributing a great deal of processing to a plurality of devices upon processing does not perform processing distribution which considers hardware resources of devices used in distributed processing. When rendering processing of a print job is executed by distributed processing using devices connected to a computer network, it is determined whether hardware or software rendering processing is executed (S1102, S1103). Image processing devices which can implement hardware or software rendering processing are sought from devices connected to the computer network (S1104, S1106). Based on the determination and seek results, devices to which jobs divided from the print job are transmitted are notified (S1108).

In a network print system in which a printer and at least one client are connected to each other through a network, and at least a part of a job for the printer can be subjected to load distributed processing by grid computing, wherein when a printer driver of the printer is installed on any one of the at least one client, the system is adapted to build a grid computing network. In this arrangement, it is easily to build the grid computing network in which the printer job is subjected to load distributed processing.

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.

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 computer system including a job scheduler which divides an input job and determines a client apparatus to assign the divided job, and a task manager which transmits the divided job to the client apparatus determined by the job scheduler, the job scheduler assigns the same job to a plurality of client apparatuses when the number of client apparatuses is larger than the number of divided jobs, and when the job is finished in one of the plurality of client apparatuses assigned the same job, execution of the job in the remaining client apparatuses is canceled so that the time until all jobs are finished is shortened.

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.
