It will be readily understood that, since each of the first printing group 5 and the second printing group 6 comprises a plurality of ink-jet heads 63, simultaneous ink ejection by the plurality of ink-jet heads 63 results in ejection of ink droplets onto the outside of the printing sheet when the width of the printing sheet is smaller than the distance between the two ink-jet heads 63 located at the two ends of the same printing group. Therefore, depending on the width of the printing sheet, the controller 4 also controls the inkjet heads 63 located above the area covered by the printing sheet to perform inkjet printing during printing, and the inkjet heads 63 located outside the area covered by the printing sheet do not eject ink.

Referring to fig. 1, a drying assembly 8 is disposed between the second printing assembly 6 and the second limiting seat 31, the drying assembly 8 includes a box 81, an opening allowing the printing paper to pass through is disposed on the box 81 along a moving direction of the printing paper, and an electric heating element (not shown in the figure) is disposed in the box 81. The printing paper passes through the drying component 8 after being subjected to multi-pass inkjet printing, so that ink marks on the printing paper are dried, and the damage of images after printing due to mutual contact of different layers when the printing paper is rolled on the second roller 32 is avoided. In the present application, when the number of the printing elements is greater than two, the drying element 8 is disposed between the printing element at the end and the second stopper 31.
Referring to fig. 2, the intermittent multicolor inkjet printer provided by the present application may further include a remaining paper detection sensor 9 and an alarm 91.
