1. Field of the Invention
The present invention relates to an output apparatus for printing and displaying document data sent from a host computer or the like as a set of dot data.
2. Related Background Art
FIG. 1 is a block diagram showing an embodiment of the present invention;
FIGS. 2A and 2B are views showing formats of document data;
FIG. 3 is a view showing a relationship between a mesh pattern character and enlargement; and
The preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a block diagram showing an arrangement of an output apparatus according to an embodiment of the present invention. The output apparatus includes an input interface (input I/F) 101 for receiving document data 121 from a host apparatus such as a host computer 120, a page memory 102 for storing the document data in units of pages, and a font memory 103 for storing a character font pattern and a screen pattern such as a mesh font pattern associated with the present invention.
On the host computer 120 side, document data is input at a keyboard 122 or an image reader 123. In addition, the host computer 120 designates a magnification in enlargement/reduction processing.
