    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： A printing system in which it is determined whether the print heads of a printer are effectively aligned and, depending on whether or not the print heads are effectively aligned, one of multiple different printing schemes is selected for controlling printing of a print job, wherein the selected printing scheme for the case when the print heads are not effectively aligned includes controlling printing by directing the printer to use only one selected print head.

    摘要： A printer driver executable in a computer connectable to a driven printer. In response to initiation of a print job, the print driver obtains current status of the printer. Based on the status of the printer, the print driver modifies operational parameters of the printer prior to commencement of the print job, so that the operational parameters are different from default ones of such parameters. In addition, the print driver modifies its own operational sequence based on the printer status, so that the operational sequence of the printer is different from a default sequence without such status information.
