The paper bin box 17 and the printer head assembly 13 are respectively arranged in the cavity 12. The head assembly 13 includes an elongated head assembly 14, and a head 15 may be installed and ink obtained from the head assembly 14 is ejected through the head 15. The nozzle assembly 14 includes a plurality of nozzles 15 arranged along a length direction of the nozzle assembly 14, the plurality of nozzles 15 face the printing medium 16 of the paper cartridge 17, and can eject ink to the printing medium 16, and the length of the nozzle assembly 14 is greater than or equal to a width of the printing medium 16. In some embodiments, print medium 16 may be printing paper or photographic paper. In some embodiments, each head assembly 14 may independently contain a single color of ink, for example, a color head assembly and a black head assembly, and may continue to eject ink, color printing. The color nozzle assembly may include, but is not limited to, cyan nozzle assembly, magenta nozzle assembly, and Yellow nozzle assembly. Each spray head assembly 14 facilitates independent replacement arrangements. The spray head 15 of each spray head assembly 14 is detachably arranged on the spray head 15 of the spray head assembly 14, so that the spray head 15 is convenient to replace and arrange independently. The ink bag is connected to the printhead assembly 13 and can supply ink to the printhead assembly 13. The elongated head assembly 14 thus disposed inside the chamber 12 of the printer 10 can effectively eject a line of ink onto the print medium 16 along the width of the print medium 16, and the ink is ejected toward the print medium 16 through the plurality of heads 15 arranged along the length direction of the head assembly 14. Meanwhile, the length of the nozzle assembly 14 is greater than or equal to the width of the printing medium 16, so that the nozzle assembly 14 does not need to be controlled to transversely move back and forth during printing, a complete line (along the length direction of the nozzle assembly 14) of ink can be jetted to the printing medium 16, and the printing efficiency is improved.

In some embodiments, printer 10 includes an ink supply tube (not shown) and an ink cartridge (not shown); the ink bag is arranged in the ink box and is connected with the printer head component 13 through an ink supply pipe.

In some embodiments, the plurality of showerhead assemblies 14 have a first spacing therebetween, and the plurality of showerheads 15 of each showerhead assembly 14 have a second spacing therebetween that is less than the first spacing. In this way, when the printing medium 16 passes through the nozzle assemblies 14 with the first interval in sequence, ink is only jetted on the printing medium 16 which is required to be jetted by each nozzle assembly 14, so that the ink jetted by the nozzles 15 of different nozzle assemblies 14 is prevented from interfering with each other, and the printing effect is improved. The second interval is as small as possible, for example, when all the nozzles 15 in one nozzle assembly 14 eject ink, the ink ejected by the nozzles 15 is dense and continuous, and can eject a complete transverse line along the transverse direction of the printing medium 16 (the length direction of the nozzle assembly 14), so that the ink ejection reliability of each nozzle assembly 14 can be effectively improved. Wherein, the nozzles 15 of the plurality of nozzle assemblies 14 are arranged in the same row and in the same interval, thus improving the printing effectiveness. The heads 15 of the plurality of head assemblies 14 may also be staggered and spaced so that ink ejected effectively covers a lateral area of the print medium 16.

In some embodiments, the length of printhead assembly 14 is perpendicular to the direction of conveyance of print media 16. The conveying direction of the printing medium 16 is the longitudinal direction of the printing medium 16, i.e., the longitudinal direction of the printing medium 16. In this way, the length direction of the nozzle assembly 14 is parallel to the width direction of the printing medium 16, i.e. the transverse direction of the printing medium 16, the paper conveyer 25 vertically conveys the printing medium 16 during printing, the nozzle 15 continuously performs ink jet control, so that the nozzle assembly 14 can eject a complete row of transverse data, and the nozzle assembly 14 does not need to be controlled to move during printing. Wherein the length of the nozzle assembly 14 can support the maximum width of the print media 16.
