The object of the invention is to provide an electrophotography recording paper having excellent density, color tone, gradation, fixing properties, and recording qualities, while having excellent water resistance, and durability. When the projectile fishtails and one or more of the bumpers come into contact with the air-water boundary, the water imparts torque and a rebounding force to push the projectile completely back into the air cavity. The bus bridge can store programmable values for the DMA read latency and write latency.
