<p>Central processing unit (112), responsive to the commands and print data signals, selectively stores the reference pattern signals from a pattern memory into a page memory (132). The central processing unit (112) provides the first page pattern signal stored in the page memory (132) to the laser printer engine (152) for use in printing the first page while simultaneously providing the second page pattern signals from the pattern memory to the page memory to build the second page in the page memory (132). After the first page pattern signals have been provided to a laser printer engine (152), the central processing unit (112) provides the second page pattern signals stored in the page memory to the laser printer engine for printing while simultaneously providing the subsequent page pattern signals from the pattern memory to the first page memory to build the subsequent page in the page memory (132). A bus interconnects the computer (106) and the central processing unit, the pattern memory and the page memory and the page memory and the laser printer engine.</p> |
