    Abstract: 公开了一种双面打印机(80)及其控制方法。双面打印机包括第一打印头(86a)和第二打印头(87a),且第一打印头和第二打印头在打印介质输送方向(891)间隔距离L。该双面打印机的控制方法包括:接收第一票据的第一数据;判断当前打印是否为首次打印;在确定当前打印为首次打印的情况下,控制第二打印头打印第一票据的固定长度数据;或者,在确定当前打印不是首次打印的情况下,控制第一打印头在打印介质的第一面打印第一票据的第一数据,并控制第二打印头在打印介质的第二面依次打印第一票据的可变长度数据和第二票据的固定长度数据,其中第一票据和第二票据为前后相邻打印的两张票据。上述打印机能够在不影响打印速度的情况下消除打印介质第二面的空白区域,并提高打印介质第二面的利用率。
