A heating plate is arranged on the plate, which can surround the ink outlet of the nozzle component. Compared with the current conventional printers that heat the ink cartridge corresponding to the nozzle component, the present application can avoid the problem that the ink in the ink cartridge has a long flow channel to the ink outlet, and the gradual cooling increases the viscosity of the ink at the ink outlet, thereby causing the ink to be not smooth. A heating plate is arranged around the ink outlet of the nozzle component to heat the ink in the ink outlet, thereby ensuring the smoothness of the ink outlet, and then ensuring the printing effect of inkjet printing in the digital printing process, which is conducive to the widespread application of digital inkjet printing.
