The invention discloses an alignment layer printing system and a control method of a printing device and relates to the technical field of alignment layer printing for solving the problem that white points on substrates are increased suddenly as an alignment liquid is not uniformly diffused on a glue homogenizing roller and a transfer plate when an existing printing device is converted from an idle state into a printed state. The alignment layer printing system comprises a printing device and a control unit, wherein the printing device comprises a stand for drip and a printing assembly; the control unit is used for controlling the stand for drip to spit the alignment liquid to the printing assembly at a first split amount for at least one substrate of n substrates in the process of printing the previous n substrates when the printing device is converted from the idle state into the printed state, wherein n is a preset value; the first split amount is the actual split amount corresponding one substrate; and th
