PURPOSE:To print optimum image required by user all the time. CONSTITUTION:When data from a host device is character data, a descriptor for constituting pages is formed. When it is a command other than an emulation switching command or control code, a process corresponding to it is performed. When it is the emulation switching command, it is determined whether a pointer PTR pointing a head of the descriptor is '0' or not. When PTR='0', the emulation is switched immediately. When PTRnot equal to '0', it is determined whether an overwrite mode is a forced output mode or not. If it is the forced output mode, pages are constituted based on the descriptor made till then. It is printed out and the emulation is switched. If it is the overwrite mode, the emulation is merely switched in order to add it to the descriptor made till then. |
