  • Patent number: 11755861
    Abstract: A printing system includes a printing unit, a position determiner that randomly determines a position where a first information code is to be set, a modifier that modifies print data for printing an image, the first information code, and a positional information code having recorded therein positional information at the time of printing that indicates the position determined by the position determiner so that the first information code is set at the position determined by the position determiner, an acquirer that acquires the position of the first information code on a print medium as positional information and acquires the positional information at the time of the printing from the positional information code, and a determiner that determines whether the printing result is a falsified matter based on comparison of the positional information after the printing with the positional information at the time of the printing.

  • Patent number: 11713206
    Abstract: A medium loading device includes a side end aligning member which is positioned at a standby position when a medium is ejected; and a control section. When a value based on first information relating to recording density of a medium to be ejected this time and at least one medium among the media ejected previously is equal to or greater than a threshold value, the control section specifies a first position, which overlaps the medium to be ejected this time, as the standby position, and when the value based on the first information is less than the threshold value, the control section specifies a second position, which does not overlap the medium to be ejected this time, as the standby position, and the control section adjusts the threshold value based on second information relating to at least one medium among the media recorded before the ejection at this time.
