Image forming device and image formation method

A print control method comprising the steps of measuring a battery remainder index correlating with a remaining capacity of a battery in a printing unit operating on the battery, specifying a number of remaining printable copies of the printing unit on the basis of the battery remainder index, and outputting the number of remaining printable copies.

Print control method

A printer driver () divides printing data, which controls printing of a printer, into one or plural data to record the data, to each of which information for discriminating the data is added, as a sub-file (), as well as creates a sub-file name data () for specifying the sub-file () and records it as a spooling file (). The printer driver () also creates a file () for writing a print controlling command and records the file name thereof in the spooling file (). When a print cancellation instruction is received during the printing performance, a print cancellation command is written in the file (). The print processor () refers the print spooling file () to read the sub-file () in order, so that the printing data included in the file would be transferred to a printer (). The completely transferred sub-file is deleted. The print processor () monitors the file () while the printing data is transferred to the printer (), and stops the following printing when the cancellation command is written.

Methods for creating printing data and for transferring printing data

Quality of printing is easily improved without applying surface finishing after printing. A printer that prints an image based on image data, on a print medium, using a plurality of color inks. The printer comprises a colorless clear ink printing means which prints the print medium using a colorless clear ink, a print setting receiving means which receives settings relating to printing, and an area determination means which determines an area in which the colorless clear ink is used, based on at least either said image data or said settings relating to printing.

Printer, print control unit, print control method and print control program product

A printing apparatus of the present invention prints an image corresponding to image data, which are divided into a plurality of pages and supplied from an application program, on a roll of machine glazed paper without any margin set between the adjoining pages. This arrangement enables printing on a large-sized printing medium, such as a banner. A printer driver incorporated in the printing apparatus causes the image data divided into the plurality of pages to be subjected to halftone processing according to an error diffusion method. When a standard printing mode is specified, an error buffer is initialized on every instruction of a new page. When a continuous printing mode is specified, on the other hand, the error buffer is not initialized. This causes an error occurring in a certain pixel included in one page to be diffused to pixels included in a next page in the continuous printing mode. The arrangement of the present invention enables the image data divided into a plurality of pages to be collectively processed by the halftone processing and thereby improves the picture quality of the image especially in the vicinity of a boundary between the adjoining pages.

A pattern of continuously printing a sheet without any margin between images and cutting a boundary between the images, a pattern of continuously printing the sheet with a margin between the images and performing two upper and lower cuttings at the places slightly inside the image around boundaries between the image and each of the margins, and a pattern of continuously printing the image obtained by cutting upper and lower ends of the original image without any margin between the images and cutting the boundary between the images are prepared beforehand. To execute the printing, an instruction as to the method for performing the printing is received from a user. This provides a printing system of printing the continuous sheet, subsequently automatically cutting the sheet, and outputting a standard-size printed matter without any margin, wherein the plurality of patterns can be switched regarding a printing mode and cut position of the image to complete the printing.

A printer host comprising a list-forming unit for forming a band-corresponded drawing command list showing correspondence of respective drawing commands to a band or bands referring to a spool file stored in a hard disk device; a drawing command storage control unit which successively reads out the drawing commands corresponding to the respective bands from the spool file stored in the hard disk device according to the band-corresponded drawing command list, and stores the drawing command of one band that is read out in the drawing command memory; and an image data expanding unit which converts the drawing command of one band stored in the drawing command memory into image data and expands the image data in the band memory. This constitution makes it possible to decrease the number of drawing commands stored in the memory in the host.

Printer host and storage medium storing the operation program therefor

In a printing apparatus of the present invention, image data divided into a plurality of pages and supplied from an application program are printed on a roll of machine glazed paper without any margins set between adjoining pages. This arrangement enables a large image to be printed on a large-sized printing medium, such as a banner. A printer driver in the printing apparatus sets feeding amounts of sub-scan according to a selected printing mode. In the case where a standard printing mode is selected, the printer driver sets the feeding amounts to execute an upper end process and a lower end process with regard to each page. In the case where a continuous printing mode is selected, on the other hand, the printer driver maintains a periodic variation of standard feeding amount, except the upper end process carried out in a first page. When a print head is located across a boundary between adjoining pages in the course of printing in the continuous printing mode, print data with regard to the adjoining two pages across the boundary are output to the respective nozzles, and specific areas immediately before and after the boundary are recorded simultaneously by one pass of the main scan. This arrangement of the present invention effectively prevents banding from occurring in the vicinity of the boundary.

Printing apparatus for continuous printing

In conventional ink jet printers there has been a problem such that with a decrease in residual quantity of ink, the density of the ink becomes lower and so does the print density. In a color conversion processing which a color conversion module executes in a printing data generating process executed by a printer driver an amount of ink used is acquired with respect to ink contained in each of ink cartridges and and the degree of variations in ink density is acquired on the basis of the amount of ink used. Then, on the basis of the degree of variations in ink density, a correction coefficient table TBL is retrieved to acquire a correction coefficient associated with print density.

When a plurality of types of image data are superposed and written onto a color information virtual drawing screen, attribute information of each pixel is written onto an attribute information virtual drawing screen so that the image data can be read out for every type. When results of superposition are read out from a virtual drawing screen for an interpolating process, the results are read out for every type of image data on the basis of the attribute information so that an optimum interpolating process suitable for each type is carried out. Since a margin of each image data is affected by the interpolating process, superposition after the interpolating process is controlled so that the margin is rendered most suitable. As a result, optimum results of interpolation can be achieved even when a plurality of types of image data are co-existent.
