摘要:
A printer has a queue for queuing a queued execution command, an immediate execution agent for executing a write command, and a queued execution agent for executing a read command. The immediate execution agent immediately executes the received write command, and writes data in a host. The queued execution agent picks up a read command from the queue, and reads out data from the host. The host appends a data transfer request from the printer to a queue, issues a write command to the printer on the basis of that data transfer request, and issues a read command to the printer on the basis of a print data transmission request or the like from an application. Independent full-duplex channels can be provided in two directions. Also, a write command can be immediately processed.

An information processing apparatus includes an acquiring unit for acquiring information stored in a memory of a printing device connected through a bidirectional interface, and a selecting unit for selecting a printer driver corresponding to the information acquired by the acquiring unit from a plurality of printer drivers on the basis of the information.
摘要:
A communication system for issuing commands from an initiator to a target, thereby allowing the target to write or read out data into/from a memory area which the initiator has and exchanging the data. The initiator transmits read and write commands for the memory area to the target so as not to exceed the total number of commands which can be held by the target. The target holds the received read and write commands, holds references to the commands by different queues, and independently processes the commands, so that the number of the commands to be transmitted can be managed efficiently.

An information processing apparatus includes an acquiring unit for acquiring information from a printer connected through a bidirectional interface, and a control unit for controlling a display status of a virtual printer, which is displayed on a display screen and represents the printer, on the basis of the information acquired by the acquiring unit. An output apparatus includes a setting unit for setting an operating environment, and a changing unit for changing operating environment information set by the setting unit on the basis of information acquired from an information processing apparatus connected through a bidirectional interface.

It is an object to print an image as it is inherently formed. Objects constructing the image are separated to character train objects in which there is no need to consider an overlap and the other objects by a character train separator. A character train converter converts the separated character train objects in which there is no need to consider the overlap into character code information and transmits to a printer. The other objects are converted into image information by a drawer and transmitted to the printer. The printer synthesizes a glyph formed by a glyph generator from the character code information onto the received image information and outputs.
摘要:
An information processing apparatus for communicating information with an information device. The information processing apparatus accesses virtual device image data representing an image of the information device, obtains status information representing a status of the information device from the information device through a bidirectional interface, and controls a display to display a virtual device image of the information device based on the accessed virtual device image data and the obtained status information. The virtual device image is a visual representation of the physical appearance of the information device in the status represented by the obtained status information.

A process for producing crosslinked polymer particles which comprises a first step of polymerizing a polymerizable monomer containing from 0.1 to 2.0% by weight, based on the entire polymerizable monomer, of a crosslinkable monomer in a medium in which the polymerizable monomer is soluble but the resulting polymer is insoluble, to obtain crosslinked polymer particles having a particle size of from 0.8 to 10 .mu.m, and a second step of letting the crosslinked polymer particles absorb from 1 to 50 times by weight of a polymerizable monomer containing from 2 to 100% by weight, based on the entire polymerizable monomer, of a crosslinkable monomer in an aqueous medium, followed by polymerization to obtain crosslinked polymer particles having a particle size of from 1 to 30 .mu.m and a crosslinking degree of from 1.0 to 98%.
摘要:
An initiator holds commands corresponding to ORBs issued to a target in an I/O request queue until it receives a completion response from the target. The target has read and write execution agents, and processes commands from the initiator. When a connection between the initiator and target is disconnected, and is connected again, the initiator deletes all ORBs, and generates and issues ORBs again to the target on the basis of the commands held in the I/O request queue. Upon processing an ORB, the target holds an identifier of the ORB whose processing is in progress, and the address of a buffer which is undergoing a read or write. After re-connection, the target compares the held identifier with the identifier of an ORB re-issued by the initiator. If the two identifiers match each other, the target restarts the read or write from the held address. If the two identifiers do not match, the target determines that the corresponding ORB has already been processed, and sends back processing completion status to the initiator.
