摘要:
Device abstraction units 28a and 28b respectively transmit various pieces of control information and data to and from devices 34a and 34b, and carry out abstraction of the devices 34a and 34b (that is, abstraction of the hardware) with respect to upper constituents. Interface units 22a and, 22b transmit various pieces of control information and data to and from the device abstraction units 28a and 28b, and provide an application unit 20 with an identical interface. Communications path abstraction units 24a and 24b carry out abstraction of communications paths 26a and 26b in the process of transmission of various pieces of control information and data via the communications paths 26a and 26b across a process boundary or a network boundary. This arrangement of the present invention enables a substantially fixed control according to an applications program, regardless of the type of the device or the type of the communications path.

A first half-tone processing means 110 half-tone processes image data blocks using an error diffusion method. A second half-tone processing means applies a half-tone process for error value calculation on a leading portion of each image data block before the normal half-tone processing. Two error buffers store the error values output by the first half-tone processing means successively to the leading error values already stored by the second half-tone processing means. Two data buffers store the process result from the first half-tone processing means. The first half-tone processing means starts half-tone processing the image data blocks using the leading error values stored in the two error buffers.

A correlation element 134 correlates a source device with a destination device according to an instruction given by the user. A decision element 122 determines whether or not a certain combination of device classes is operable as a composite device. In the case of the affirmative answer, a determination element 136 identifies the type of the composite device and specifies a user interface for operating the composite device. A data output element 132 then displays the specified user interface in a window on a monitor 170 at a specific timing. This arrangement effectively improves the operatability of the device control.

[Problem]To suppressing part of an image not being recorded even when the image to be recorded does not fit in an area defined by the top, bottom, left, and right margins set by an application.[Solution]If the size of the image to be recorded is larger than the application-specified area defined by the margins when image information including information denoting margins on cut-sheet paper is input from an application execution unit, the printer driver execution unit of the host computer virtually enlarges the positions of the sides of the cut-sheet paper, and generates and outputs to the printer a control command to record the image described by the image data in an enlarged area, which is an area defined by sides separated by the margin from the virtually enlarged sides.
摘要:
The technique of the present invention intermediates between an arbitrary client and an arbitrary printer connecting with a network to actualize practical printing works.A print portal system utilizing a server connected to the network intermediates between the client and the printer to execute a printing operation. The client outputs a printing requirement, which specifies print data of interest and a printer as an output resource, to the print portal system. The print portal system converts the input print data into data of a general purpose format, which does not depend upon the type of the printer, and transfers the converted print data to the specified printer.

摘要:
A control system built around plural common objects is provided with greater flexibility and easy customizability, and a programming method for the control system is provided. An interface object (15) capable of two-way communications is created and used when first OCX (10), a common object, creates and controls second OCX (11). This interface object (15) is able to return events generated by second OCX (11) to first OCX (10), and first OCX (10) is able to completely control the operation of second OCX (11).
