Abstract: A bit-image printer is disclosed, having a page memory, (11) a font memory (14) and a font library (16). Fonts are selected from the library for use in composing a page image in the page memory. Loading of font characters into the page memory is controlled by the position of a cursor located within page memory. The font characters include cursor parameters which control the loading of the character into page memory, based upon current cursor position, and control movement of the cursor to a new location, in preparation for loading of the next character into page memory. After a page image is composed, the image is used to control an LED printhead (10) which images the photoconductor (12) of a xerographic reproduction device.

Abstract: A method of facsimile transmission which utilizes pattern matching, whereby the appearance of the transmitted facsimile and the compression performance are enhanced. The appearance of the respective prototype symbols is enhanced by using the average of images that match the same pattern as the prototype. Compression performance is enhanced by incorporating white space parameters into prototypes thereby eliminating the need to send positional identification when each character ID is sent.
