Abstract: A data processing apparatus communicating with a printer through a predetermined communication medium, in which a printer command forming unit constructs a print image by analyzing a drawing command formed by an operating system and forms a printer control command based on the print image; a first obtaining unit obtains feature information to presume print processing times by the printer command forming unit where a specific compression method is used and where it is not used; a discriminating unit discriminates whether the printer command forming unit should use the specific compression method or not based on the feature information obtained by the first obtaining unit; and a controller switches and controls whether to apply the specific compression method in forming the printer command based on a discrimination result of the discriminating unit.

Abstract: A print control apparatus for processing print information, which is connected to a printer, selects the optimal print mode for a set condition. The apparatus controls a printer driver to generate print data in the selected print mode in accordance with a print instruction generated by a graphics engine, thereby increasing the print throughput of the printer and allowing proper printing.

Abstract: A data processing apparatus which communicates with a printer forms trial compressions of image data to discriminate whether sufficient compression has been obtained. A print image is produced by analysis of a drawing command, and a print control command is formed based on the print image. Image data is compressed in a predetermined segment by applying a specific compression method so as to obtain size information. Based on the size information, a discrimination is made as to whether the specific compression method is to be applied to the image data. This discrimination is made repeatedly for each predetermined segment. A print control command is formed if the size information indicates that the size of the compressed data is smaller than a threshold, whereas the print control command is not formed if the size of the compressed data is not.

Abstract: A data processing apparatus which can communicate with a printer through a predetermined communication medium is constructed by: a printer command forming unit for constructing a print image by analyzing a drawing command which is formed by an operating system and for forming a printer control command which is based on the print image and should be transferred to the printer; a first obtaining unit for obtaining feature information to presume print processing times by the printer command forming unit in the case where a specific compression method is used and the case where it is not used; a discriminating unit for discriminating whether the printer command forming unit should use the specific compression method or not on the basis of the feature information obtained by the first obtaining unit; and a controller for switching and controlling the formation of the printer control command which is formed by the printer command forming unit and to which the specific compression method is applied and the formation

Abstract: There is provided an information processing system capable of always ensuring output with a predetermined number of output sheets, and an information processing method and a recording medium therefor. A printer control system is composed of a host computer on which a printer driver constituting a printer control command generating program is operable, and a printer capable of processing the data as if the data have been received by a designated number of times, wherein the host computer is provided with an external memory for temporarily storing the maximum data amount of the received data temporarily storable in the printer, and a printer driver for discriminating whether the total data size of the printer control commands exceeds the maximum data amount, and, in case of excess, outputting the temporarily stored printer control commands by a designated number of times to the printer.
