摘要:
There is provided an output apparatus for receiving code data from a data source of a host computer and developing into pattern data and outputting. The apparatus comprises: a pattern generator to generate pattern data; a memory to store the pattern data generated from the pattern generator as a font cache; and a controller for controlling in a manner such that when a residual amount of the memory is less than a capacity enough to store other data which is newly input and whose priority regarding the storage is higher than the priority of the pattern data, the pattern data of the font cache is deleted and the newly input data is stored. An auxiliary character font, form data, or a macro instruction is used as data which is newly input. The pattern data of the font cache in the memory is deleted on the basis of the priority. The pattern data is a dot matrix font pattern which was developed from a nondot matrix font.
