ABSTRACT:
A printing device comprises a page memory and a printing section. The printing device further comprises a font stack memory and a control circuit. The font stack memory stores the combination of the character code and the attribute information corresponding to a bit map font stored in the page memory, together with the coordinate information identifying that area of the page memory in which the bit map font is stored. The control circuit receives a series of character codes together with attribute information and layout information, and checks whether or not each character code is registered in the font stack memory together with the attribute information allotted to the character code. When it is detected that the combination of the character code and the attribute information is registered, the control circuit reads out the bit map font from that memory area of the page memory which is identified by the coordinate information registered together with the combination of the character code and the attribute information, and stores the readout bit map font into that area of the page memory which is specified by the layout information allotted to the character code and the order of the character code. The printing section prints a printing pattern constituted by the bit map fonts stored in the page memory according to the series of the character codes.
