The control module performs a secondary determination on the structural stability of the spray terminal according to the average power consumption U of the pressing motor when Q1<Q≤Q2, wherein the control module is provided with a preset power consumption U0. If U≤U0, the control module secondarily determines that the structural stability of the spraying terminal is within the allowable range; If U>U0, the control module determines that the structural stability of the inkjet printing terminal is lower than the allowable range, calculates the difference △U between the average power consumption U of the pressing motor and the preset power consumption U0, and adjusts the vertical height of the inkjet printing to the corresponding vertical height according to △U; When the control module completes the adjustment of the paper feeding motor speed, it determines whether the printing efficiency meets the requirements according to the number of stamps C in a unit time, wherein the control module is provided with a preset number of stamps C0. If C<C0, the control module determines that the stamping efficiency does not meet the requirements, calculates the difference △C between the preset stamping quantity C0 and the stamping quantity C per unit time, and adjusts the speed of the paper feeding motor for a second time according to △C; If C≥C0, the control module determines that the printing efficiency is within an allowable range.
