FONT SELECTION AND COMPRESSION DEVICE FOR A PRINTER SUBSYSTEM |
摘要 |
A printer subsystem receives command and data information from a host system and retains a large number of font images in an associated storage area within the printer subsystem. A base font image set is ordinarily selected by the user but provision is made to dynamically change the font images as may be required in a real time fashion during actual printing operations. The font images are stored in a compressed form in the storage area. Routines involve use of pointer tables and data tables. It is possible to select an entire set of new font images in place of the base set of images or to modify only selected character images within the base font image set. |
