Russell Campbell, Richard M Dow, Timothy P Blair, Burton H Poppenga: Memory partitioning for multi-resolution pauseless page printing. Hewlett Packard Company, Lane R Simmons, March 21, 2000: US06040917 (22 worldwide citation)

A multi-resolution capable printer includes a critical operations memory buffer for enabling critical page print operations to occur without flushing the video buffers and without waiting for returned-in memory to heal into larger free blocks. The critical operations buffer thus enables improved con ...

Timothy P Blair: Reducing memory fragmentation by coalescing and redistributing previously distributed page strips. Hewlett Packard Company, Lane R Simmons, October 10, 2000: US06130759 (21 worldwide citation)

Fragmentation is reduced in a memory of an image transfer device by coalescing segments of rasterized, compressed and distributed page strips into preallocated buffers, and then redistributing the strips back into the memory such that smaller holes in the memory are filled before larger holes. Alter ...
