Abstract: Provided is a technique that enables proper sorting of discharged print media by suppressing curling of each of the print media sufficiently. A determining unit determines a curling suppressing operation to be executed such that in a case where sorting operation is executed, the suppressing operation having a higher effect of suppressing curling is executed than in a case where the sorting operation is executed. Then, a print control unit controls a print head to perform printing on print media while executing the suppressing operation determined by the determining unit.

Abstract: A print medium is conveyed in a first direction and a print head is provided with a reference side nozzle array and a plurality of nonreference side nozzle arrays. A relative position displacement amount between a reference printing position of a reference pattern printed by the reference side nozzle array and a nonreference printing position of each of nonreference patterns printed by each of the nonreference side nozzle arrays is detected. Based on a maximum value of a displacement amount of the reference printing position with respect to each of the nonreference printing positions in a direction opposite to the first direction, a first correction value for correcting displacement of the reference printing position is calculated. With reference to the reference printing position after corrected based on the first correction value, a second correction value for correcting displacement is calculated for each of the nonreference printing positions.

Abstract: A print medium is conveyed in a first direction and a printing head prints an image on the print medium by using a printable region of the print head that extends in a second direction crossing the first direction. Storing units can feed multiple sorts of print media. Among the multiple sorts of the print media, the print medium to print a check pattern for checking a printing state of the printing head is selected as the print medium to be fed from the corresponding storing unit. The check pattern is printed on the print medium by using a portion of the printable region of the printing head corresponding to a size of the print medium fed from the storing unit.

Abstract: An image forming apparatus 101 capable of performing printing with a high image quality, and a control method of the image forming apparatus 101 are provided. For this purpose, a threshold value Dt is preliminarily set that allows printing without occurrence of blur, for each of preliminarily set monitoring areas A. In the case where a print duty for each of the monitoring areas A has exceeded the threshold value Dt, an ejection frequency of ink and conveying speed of a print medium are reduced in association therebetween.

Abstract: A recording apparatus is provided for determining a relative moving speed between a recording head and a recording medium based on application amount information and power information corresponding to power for driving a heating element. In a case of the power amount in a first amount, the moving speed is determined as a first speed in a case where an application amount is equal to a predetermined amount, and the moving speed is determined as a speed higher than the first speed in a case where the application amount is smaller than the predetermined amount. In a case of the power amount in a second amount smaller than the first amount, the moving speed is determined as a speed higher than the first speed in a case where the application amount is equal to the predetermined amount.

Abstract: A print head capable of forming dots on a print medium based on print data and a print medium are caused to perform relative movement in a specified direction, and a speed of the relative movement is set according to the number of dots to be formed in an area of a specified size. Whether to set the speed of the relative movement to a first speed is determined according to the number of dots to be formed in an area of a first size on the print medium. Whether to set the speed of the relative movement to a second speed lower than the first speed is determined according to the number of dots to be formed in an area of a second size which is smaller than the area of the first size in the specified direction.
