Abstract

In a laser beam printer, printing information is sent from plural hosts and printing is carried out according to the printing information. A printing paper cassette detachment inhibition mechanism unit is provided on a printing paper cassette. The paper cassette detachment inhibition mechanism unit includes fixture grooves provided on the printing paper cassette and stop levers provided on a printing paper cassette mounting port. The printing paper cassette detachment inhibition mechanism unit inhibits the detachment of the printing paper cassette when the printing paper in the printing paper cassette has been selected for use by one of the hosts. A selected printing paper cassette display unit is provided on the laser beam printer and displays the selected printing paper cassette.
