Disclosed are a vending machine and a method of detecting height of a storage column. The vending machine may determine whether a sensor squarely faces the front end surface of the level plate of a storage column by detecting the type of an output signal of the sensor. When the sensor squarely faces the front end surface of the level plate of the storage column, the height of the level plate of the storage column may be obtained based on a height difference between the sensor and the bearing surface of a bucket and the height of the bucket. Thus, according to the height of the level plate of the storage column, the bearing surface of the bucket and the upper edge of the front end surface of the level plate of the storage column lie in the same level when dispensing an item.

Vending machine and method for detecting height of storage column

A vending machine and an item dispensing method. The vending machine includes: a storage column used to store items; a bucket used to receive an item from the storage column; a first conveying mechanism disposed at the storage column and used to convey the item in the storage column to the bucket; a second conveying mechanism disposed at the bucket and used to convey the item from the storage column to the inside of the bucket; and a controller. The first and second conveying mechanisms are each electrically connected to the controller. The item dispensing method includes controlling the first conveying mechanism to convey an item to the bucket at a first preset speed and controlling the second conveying mechanism to convey the item to the inside of the bucket at a second preset speed, as the item is entering the bucket, the first preset speed being less than the second preset speed.

The disclosure discloses a printer and a method and device for controlling the same. The method for controlling the printer comprises: detecting the number of heating units of a currently mounted printing head; acquiring a resolution, corresponding to the detected number of the heating units, of the printing head; and setting a printer parameter according to the acquired resolution of the printing head. The problem of high error rate after the resolution of the printing head of the printer is changed is solved.
