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 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.

摘要： Control of an ink ejection frequency to compensate for recording medium unevenness in printing by inducing a predetermined unevenness pattern into a recording medium, adjusting an ink ejection frequency of a print head based on the induced unevenness pattern, and controlling ink ejection based on the adjusted frequency. A plurality of print heads may be employed that may correspond to different color inks and may be controlled by a same control signal or individually. Control may also be varied for bi-directional printing based on a printing direction. The adjustment of the ink ejection frequency may be providing a predetermined recording unevenness pattern having periodic oscillations, dividing each periodic oscillation into a predetermined number of regions, setting a number of ink droplets to be ejected within each region, determining a gate array interval for each region, providing at least one parameter corresponding to a printing operation, and determining an ink ejection trigger difference for each ink droplet to be ejected within each region.

摘要： Feeding a plurality of successive sheets of a recording medium by calculating an expected time for a page end detection of a current sheet, and feeding a next sheet of the successive sheets in accordance with the calculated time, but prior to detection of the page end of the current sheet. Calculating the expected time may be detecting the page end for the current sheet, and mathematically filtering the page end detection of the current sheet with a current estimate of expected time for page end detection of the next sheet. The current estimate may be initialized after a first sheet of the successive sheets with a page end detection of the first sheet. The feeding of the next sheet may be controlled by controlling a time between the current sheet and the next sheet based on a time between the page end detection of the current sheet and a detection of the next sheet so as to obtain and maintain the time within a target range. Whether the page end detection of the current sheet is detected within a threshold amount of time after feeding of the next sheet has commenced may be determined, and where the page end of the current sheet is not detected within the threshold, the feeding of the next sheet is interrupted and a recovery process is engaged. The recovery process may be waiting for a page end detection of the current sheet and re-initiating feeding of the next sheet.
摘要翻译：通过计算当前纸张的页面结束检测的预期时间，并根据计算出的时间，但是在检测到页面结束之前，向下一张连续纸张馈送多个连续的记录介质片材当前工作表。计算期望时间可以是检测当前工作表的页面结束，并用当前的预期时间估计来过滤当前纸张的页面末端检测，以便下一张纸张的页面结束检测。可以在具有第一页的页面结束检测的连续页的第一页之后初始化当前估计。可以通过基于当前纸张的页面末端检测与下一纸张的检测之间的时间来控制当前纸张和下一纸张之间的时间来控制下一张纸张的进纸，以便获得并保持下一张纸张的时间目标范围。可以确定在开始下一张纸的供给之后的阈值时间内是否检测到当前纸张的页面结束检测，并且在阈值内未检测到当前纸张的页面结束的情况下，工作表中断，并进行恢复过程。恢复过程可能是等待当前页的页面结束检测并重新启动下一页的馈送。

摘要： An ink jet printing apparatus which performs printing by using a print head. The print head has at least a predetermined number of nozzles to eject ink. The apparatus includes a first prefiring mechanism for causing the print head to perform a prefiring operation to eject ink from nozzles of the print head for maintaining printing quality after a first time interval during a printing operation. The apparatus also includes a driving mechanism for driving nozzles of the print head based on data to be printed, and a second prefiring mechanism for causing the print head to perform the prefiring operation in a case where a number of the nozzles to be driven is changed. Preferably, the apparatus further includes a shifting mechanism for causing the driving mechanism to drive the nozzles of the print head based on the first time interval during the printing operation so as to enhance a power of ejecting ink and continue the printing operation after the first time interval without performing the prefiring operation. The shifting mechanism also preferably delays the prefiring operation to a second time interval longer than the first time interval, and after the second time interval, the first prefiring mechanism causes the print head to perform the prefiring operation. In a case where the number of nozzles to be driven is changed within a time duration after the first time interval and during the second time interval, the second prefiring mechanism causes the print head to perform the prefiring operation.
