A method to control printing on cover-opened

  Figure shows the flow of this disclosure. The printer checks the cover-open sensor of the printer before moving the carrier. The printer forces down the speed of the carrier of printing to a certain speed if the carrier speed is above that speed. The printer prints all image which is left in the print buffer in this speed while the cover opened condition. This method prevents loss of data because the printer prints all image which is left in the print buffer. Because the speed of the carrier is slowed while cover is opened, this method prevents an injury being caused by a movement of the carrier.
