In a printing device capable of increasing a printing speed, a sheet-feeding mechanism selectively feeds to-be-printed sheets placed in a longitudinal tray and a transversal tray. A memory stores a transversal maximum printing dimension corresponding to a printing unit. A processor receives a printing signal containing first and second dimensions. The processor judges whether or not a maximum of the first dimension and the second dimension is smaller than or equal to the transversal maximum printing dimension. If yes, the processor enables the sheet-feeding mechanism to feed the to-be-printed sheet placed in the transversal tray. The processor further judges whether or not the first dimension is smaller than the second dimension. If yes, the processor rotates a printing content corresponding to the printing signal by 90 degrees and then outputs a rotated content to the printing unit. If not, the processor directly outputs the printing signal to the printing unit.
