[0015] As a further preferred technical solution of the above technical solution, the printing and drying detection module further comprises a room temperature adjusting unit and an exhaust unit, wherein:

[0016] When the room temperature adjusting unit receives the first drying feedback signal, the room temperature adjusting unit performs first room temperature adjustment (increases room temperature and accelerates drying), when the room temperature adjusting unit receives the second drying feedback signal, the room temperature adjusting unit performs second room temperature adjustment (increases more room temperature and accelerates drying);
