Abstract
There is provided a printing apparatus having a font pattern memory to store portrait font patterns and a pattern converter to convert the portrait font pattern which is read out of the font pattern memory into the landscape font pattern, in which both of the portrait printing process and the landscape printing process are executed. This printing apparatus comprises: a frequency information memory such as a nonvolatile memory to store print frequency information of each of the portrait font patterns; a managing circuit to update and manage the print frequency information which is stored into the frequency information memory in parallel with the printing process; a landscape memory to store a predetermined number of landscape font patterns converted by the pattern converter on the basis of the print frequency information which is updated and managed by the managing circuit so that the landscape font patterns can be updated; and a landscape font pattern generation controller for comparing input print information with the print frequency information and for preferentially generating the landscape font pattern from the landscape memory. Thus, a desired landscape font pattern can be efficiently generated and printed at a low cost and the landscape printing process according to the latest print frequency information can be always executed.
