    摘要: Printing on a recording medium by lateral scans of a print head in accordance with print data. Content of print data is determined. Then, the print data is printed either with a first lateral scan process using a critical zone at edges in a lateral scan of the print head for printing, or with a second lateral scan process that does not use the critical zone for printing. The first or second lateral scan process is selected based on the print data. Preferably, the critical zone is sized in correspondence with ramp up non-uniformities of a print carriage on which the print head is mounted, so as to accommodate a distance between a point where print degradation due to speed non-uniformities are noticeable to a point where print degradation due to speed non-uniformities are no longer noticeable. The second lateral scan process preferably is a process in which a predetermined margin is inserted into the first lateral scan process. The second lateral scan process is used if print data for a current scan and print data for a previous scan, in at least the critical zone, are continuous print data, thereby alleviating ripple effects for the continuous data. In a case where the print data for the current scan and the print data for the previous scan are not continuous print data, the print data preferably is printed using the first lateral scan process.

    摘要: Printing which accommodates carriage speed non-uniformities by allowing both forward and reverse printing despite the presence of ringing and other overshoot anomalies in carriage printing speed. A determination is made as to whether print data for a current scan and a prior scan overlap in either of two critical zones at lateral extents of the recording medium, where carriage speed ringing and overshoot non-uniformities are most prevalent. If print data for a current scan and a prior scan overlap in either of the two critical zones, the current scan is printed in the same direction as that of the prior scan. On the other hand, if print data for the current scan and the prior scan do not overlap in either of the two critical zones, then printing of the current scan is effected in a direction opposite to that of the prior scan.

    摘要: Error diffusion halftoning in which error diffusion coefficients and/or thresholds vary, and preferably vary based on output error or on image source data plus accumulated error. Varying error diffusion coefficients and/or thresholds is observed to reduce printed artifacts. Preferably, a look-up table is provided, which may be based on output error or based on image source data plus accumulated error, and which directly provides error values for diffusion by adding to adjacent pixels, and which further may provide printer output data.

    摘要: In an information processing system, a printer driver in a host processor transfers print data to a print buffer in a serial printer having a configuration of one or more print heads. The print head configuration serially scans a predetermined number of print positions of a line and the print buffer for each print head has storage locations corresponding to the predetermined number of print positions. The printer driver determines empty storage locations of the current print head scan and sends print data for the next scan to the determined empty storage locations of the current scan in the print buffer.

    摘要: A multi-head printer, and a driver therefor, in which the multi-head printer has at least a wide width print mode and a standard width print mode. At least first and second print heads are mounted for lateral reciprocal movement across a support surface for a recording medium, with the first and second print heads being laterally displaced with respect to each other such that both the first and second print heads can print a first lateral print area and such that only the second print head can print a portion of a second and larger lateral print area. In the standard width printing mode, fully or partially overlapped printing in the first lateral print area can be effected by both of the first and second print heads. In the wide width print mode, printing by only the second print head is effected, and not by the first print head. An additional wide print mode may be provided for partially overlapped printing by the first and second print heads, with the second print head printing primarily in the second lateral print area. Based on print head configuration, such as the type and color capability of print heads mounted in the first and second print heads, available print modes are determined, from which one of the available print modes is selected for effecting printout by the printer.

    摘要: According to this invention, an intended image is transferred and printed even in a system which transfers image data by a handle upon reception of a print request list described by the file name of an image. In order to realize this, according to this invention, when a DPOF print request file which describes an image to be printed by the file name of the image exists in the memory card of a digital camera (3012) serving as an image supply side, a new file in which the file name in the print request file is replaced by a handle is generated and transmitted to a printer (1000).

    摘要: Image processing apparatus and image processing method for formation of high quality image by high-speed error diffusion processing by execution of more complicated threshold condition processing in a simple manner. When error diffusion processing is performed on multivalued image data having plural density components and the result of processing is outputted, upon execution of error diffusion processing on a first density component among the plural density components, a threshold value used in the error diffusion processing is determined based on a density value of a second density component, then the error diffusion processing is performed on the first density component based on the determined threshold value, and the result of execution of the error diffusion processing is outputted. Further, upon execution of the error diffusion processing on the second density component among the plural density components, a threshold value used in the error diffusion processing is determined based on a density value of the first density component, then the error diffusion processing is performed on the second density component based on the determined threshold value, and the result of the error diffusion processing is outputted.
