On receipt of image data printable on A4-sized paper, the device provided with A4-, A3- and B5-sized paper feeding trays 1, 2 and 3 carries out printing the data on A4-sized paper feed from the tray 1 (as shown in FIG. 2(A)). When an interrupt request takes place to temporarily suspend a current printing job and carry out a copying job using the B5-sized paper feeding tray, the device accepts the interrupt because of no need for use of the A4-sized paper feeding tray, carries out the copying job by using the tray 3 and then resumes the suspended job by using the tray 1 (as shown in FIG. 2(B)). If an interrupting copying job requires use of the A4-sized paper feeding tray, the device neglects the interrupt and continues the current printing job (as shown in FIG. 2(C)).
