Printing control method and printing device

A printing control method for resetting a printing platform of a printing device to a preset starting position, comprising:

• detecting a state of a limit switch of the printing device when receiving an electrical power-on signal of the printing device or a start printing command, the state of the limit switch including a trigger state or a non-trigger state;
• moving the printing platform according to the state of the limit switch and a route strategy, which comprises:
• driving, by a motor, the printing platform to move a preset distance from an initial stopping position along a first direction, which is designated as a first movement mode, and then to move along a second direction opposite to the first direction if the limit switch is in the trigger state;
• driving, by the motor, the printing platform to move toward the preset starting position, which is designated as a second movement mode, if the limit switch is in the non-trigger state, wherein the second movement mode is different from the first movement mode;
• wherein the first movement mode and the second movement mode are both uniform motions, and a first speed of the first movement mode is larger than a second speed of the second movement mode;
• and
• controlling the printing platform to stop moving at the preset starting position when the state of the limit switch is changed from the non-trigger state to the trigger state.
