Abstract: METHOD OF CONTROLLING A BIT-IMAGE PRINTER A bit-image printer is disclosed, having a page memory, a font memory and a font library. 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 or the character into page memory, based upon current cursor position, and control movement of the cursor to a new location, in preparation for lading of the next character into page memory. After a page image is composed, the image is used to control an LED printhead which images the photoconductor of a xerographic reproduction device.
