    • Images are printed up to the edges of printing paper while preventing ink droplets from depositing on the platen. According to the present invention, an area R for ejecting image-forming ink droplets is specified for a region lying beyond the edges of a printing paper P. The pixels of an external upper edge portion Rfp extending beyond the upper edge Pf are recorded solely by the nozzles disposed opposite the downstream slot of the platen. An internal upper edge portion Rfq, which is disposed downstream of the external upper edge portion Rfp, is recorded solely by the nozzles disposed opposite the downstream slot. When dots are recorded, blank spaces are prevented from forming in the edge portions of the printing paper, and ink droplets are prevented from depositing on the platen when the printing paper P deviates from its intended position, provided the upper edge of the printing paper P remains on the inside of the external upper edge portion Rfp or internal upper edge portion Rfq. The external upper edge portion Rfp and internal upper edge portion Rfq are selected such that their dimensions in the sub-scanning direction remains substantially the same when different recording systems or recording densities are used for the pixels, provided the printing paper used for recording the images has the same dimensions and is composed of the same material.

    • A recording apparatus can be prevented from becoming dirty, for example, due to incorrectly loading a recording medium. If a width of the recording medium that has been detected by the detection means is shorter than a width, in the direction that intersects the carrying direction of the recording medium, over which the recording information is to be recorded, then a portion of the recording information, of the entire recording information, corresponding to the width, or to less than the width, of the recording medium that has been detected by the detection means is recorded onto the recording medium by the recording head. A notice is made when the width of the recording medium that has been detected by the detection means is different from a width of the size of the recording medium that has been set with the setting means. The ON/OFF of an operation through which the detection means detects the width of the recording medium is settable.
    • 例如,由于不正确地加载记录介质,可以防止记录装置变脏。 如果由检测装置检测到的记录介质的宽度比在要记录记录信息的记录介质的传送方向相交的方向上的宽度短,则记录的一部分 对应于由检测装置检测到的记录介质的宽度或小于宽度的整个记录​​信息的信息由记录头记录在记录介质上。 当由检测装置检测到的记录介质的宽度与已经设置了设置装置的记录介质的尺寸的宽度不同时,进行通知。 检测装置检测到记录介质的宽度的操作的ON / OFF是可设定的。
