PURPOSE:To increase the kinds of characters without increasing the capacity of a memory, to reduce cost and to allow a user to freely express a sentence, by contracting a font and overlapping the same with a space. CONSTITUTION:When the printing order of a round character arrives, in a step 1, the font concerned is developed on a font buffer at first from the contracted font data stored in ROM on the basis of the character code concerned. In a step 2, the font constituted of 32X32 is contracted to a font constituted of 24X24 to be developed on a contraction font buffer SFNTBF. Next, in a step 3, font data is transmitted so that the content of SFNTBF reaches the center of FNTBF. In step 4, a round mark is overlapped with the font buffer FNTBF. Next, in a step 5, the content of FNTBF prepared as mentioned above is transmitted to a printing buffer to perform printing in the same way as usual character printing.
