摘要： A print start position is set to an appropriate position, and the time required for printing is shortened. A printing apparatus, which forms a row of dots from a print start position in a scanning direction to print on a medium to be printed, is provided with a sensor that is capable of detecting an edge, in the scanning direction, of the medium to be printed. The printing apparatus stores the result of detecting the edge of another medium to be printed, and, when printing on the medium to be printed, it reads out the stored detection result and determines the print start position based on that detection result.

摘要： A liquid ejection apparatus including a liquid ejection head having a nozzle, a cleaning mechanism, and a controller. The controller includes a timer device, first memory section, second memory section, power supply, determining section, and tracked time correction section. If determination of the determining section is positive when the power supply is resumed, the tracked time correcting section reads out tracked time information from the second memory section and causes the timer device to start time tracking from the time indicated by the tracked time information that was stored when power supply to the liquid ejection apparatus was stopped. If the controller determines that the difference between the tracked time and the end time indicated by end time information stored in the first memory section is longer than or equal to a predetermined period, the controller operates the cleaning mechanism to carry out the cleaning.

摘要： A liquid ejection head is caused to eject liquid droplets at a region where no target medium is placed, such that such that a first prescribed number of liquid droplets are flushed from each of the nozzle orifices in the nozzle arrays of the first group, and a second prescribed number of liquid droplets are flushed from each of the nozzle orifices in the nozzle arrays of the second group. At least a part of the first prescribed number of liquid droplets and at least a part of the second prescribed number of liquid droplets are flushed by alternately performing a first unit operation for flushing a third prescribed number of liquid droplets which is smaller than the first prescribed number and a second unit operation for flushing a fourth prescribed number of liquid droplets which is smaller than the second prescribed number.
