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.
摘要翻译：控制喷墨频率以通过将预定的不均匀图案引入记录介质来补偿印刷中的记录介质不均匀性，基于感应的不均匀图案调节打印头的喷墨频率，并且基于调节的频率来控制喷墨。可以使用可以对应于不同颜色的墨水的多个打印头，并且可以由相同的控制信号或单独地控制。也可以根据打印方向对双向打印进行控制。喷墨频率的调节可以是提供具有周期性振荡的预定记录不均匀图案，将每个周期性振荡分成预定数量的区域，设定要在每个区域内喷射的墨滴数量，确定每个区域中的门阵列间隔区域，提供对应于打印操作的至少一个参数，以及确定每个区域内要喷射的每个墨滴的墨水喷射触发差。

摘要： In an ink jet printer having plural ink ejection nozzles on a print head, additional firings are added for each print element so as to ensure that the ink jet nozzles remain unclogged during printing. The extra firings are effected directly onto the recording medium in a controlled way so as to ensure that printout quality is not adversely affected. Particularly, extra firings of lighter-colored inks are effected over regions of darker colored ink, and any color shift caused thereby is compensated by changing printout data in the surrounding region.

摘要： In a print system for causing a printer to print an image on the basis of image data supplied from a portable communication apparatus by direct communication between the portable communication apparatus and the printer, the print function of the printer is obtained. When print conditions input by using the UI of the portable communication apparatus cannot be implemented by the print function of the printer, the portable communication apparatus requests a server to execute corresponding processing. A result processed by the server is received, and the printer is caused to print the image.

摘要： Feeding a recording medium through a printer for printing images on the recording medium by actuating a line feeding motor in predetermined stepped increments, feeding the recording medium through the printer by a line feeding device driven by the line feeding motor, printing a image on the recording medium by a print head scanning across the recording medium and ejecting ink from nozzles, the print head having j nozzles spaced at a predetermined pixel resolution that is less than a pixel resolution printed by the printer, j being an integer number, controlling the actuating step to actuate the line feed motor in stepped increments, and controlling the j nozzles utilized in printing the image. For each stepped increment of the line feed motor, the line feeding device feeds the recording medium (m×1/n) pixels of the print head pixel resolution, where m and n are integer numbers and m is greater than n. The j nozzles that print in any one scan of the print head are controlled based on the number of increments of the line feed motor. Additionally, a print driver calculates a line skip amount and a buffer offset amount, and adjusts a starting position for storing of the image data in a print buffer in a case where a first line of image data to be stored in the print buffer is white data.

摘要： A recording system for printing a high resolution image. Low resolution print data is transferred from the host computer to the printer and expanded into high resolution print data in the printer, such as by using a predetermined pixel pattern or a pattern key. The pixel pattern is changed in each of the plurality of printing scans, such as by changing the scanning frequency, to eject additional ink droplets per pixel. An image process, such as an output correction process, is performed by the host computer to determine the pixel pattern and pattern key information for printing a high resolution image. Also, power required to be supplied to the print head is reduced by changing the pixel pattern.

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.
