The end effector of claim 1 wherein said anvil comprises: a first surface comprises a first longitudinal row of first forming pockets, wherein said first staple cavities can be aligned with said first forming pockets;a second surface comprising a second longitudinal row of second forming pockets, wherein said second staple cavities can be aligned with said second forming pockets; anda wall extending between said first surface and said second surface. 3. The end effector of claim 1, wherein said anvil comprises a first slot configured to receive said first portion of said firing member, and wherein said cartridge comprises a second slot configured to receive said second portion of said firing member. 4. The end effector of claim 1, wherein said first portion and said second portion of said firing member define a distance therebetween configured to establish a distance between said anvil and said deck. 5. The end effector of claim 1, wherein said plurality of drivers comprises a first longitudinal row of staple supports configured to support said first staples and a second longitudinal row of staple supports configured to support said second staples, wherein said drivers are movable between an unlifted position and a lifted position, and wherein one of said first longitudinal row of staple supports and said second longitudinal row of staple supports is positioned closer to said anvil when said drivers are in said unlifted position. 6. The end effector of claim 1, wherein said firing member comprises a knife edge. 7. The end effector of claim 1, wherein said firing member comprises at least one inclined surface configured to lift said drivers toward said anvil. 8. An end effector for fastening tissue, comprising: a proximal end;a distal end;a first jaw comprising a cartridge, wherein said cartridge comprises a deck and a plurality of staple cavities, wherein said plurality of staple cavities are arranged in a first longitudinal row of staple cavities and a second longitudinal row of staple cavities, and wherein said deck is configured to support tissue;a plurality of first staples removably stored within said first longitudinal row of staple cavities;a plurality of second staples removably stored within said second longitudinal row of staple cavities;a second jaw comprising an anvil, wherein said anvil comprises a planar tissue-engagement surface and forming pockets;a plurality of staple drivers, wherein said staple drivers are configured to lift said first staples and said second staples toward said anvil, wherein said anvil and said plurality of staple drivers are configured to cooperatively deform said first staples to a first deformed height and said second staples to a second deformed height, and wherein said first deformed height is different than said second deformed height; anda firing member movable toward said distal end, wherein said firing member is configured to lift said staple drivers toward said anvil, wherein said firing member comprises a first portion configured to engage said first jaw and a second portion configured to engage said second jaw, and wherein said firing member is configured to relatively position said anvil and said cartridge. 9. The end effector of claim 8, wherein said deck comprises: a first deck surface, wherein said first longitudinal row of staple cavities is defined in said first deck surface;a second deck surface, wherein said second longitudinal row of staple cavities is defined in said second deck surface;a wall defined between said first deck surface and said second deck surface. 10. The end effector of claim 8, wherein said anvil comprises a first slot configured to receive said first portion of said firing member, and wherein said cartridge comprises a second slot configured to receive said second portion of said firing member. 11. The end effector of claim 8, wherein said first portion and said second portion of said firing member define a distance therebetween configured to establish a distance between said anvil and said deck. 12. The end effector of claim 8, wherein said plurality of drivers comprises a first longitudinal row of staple supports configured to support said first staples and a second longitudinal row of staple supports configured to support said second staples, wherein said drivers are movable between an unlifted position and a lifted position, and wherein one of said first longitudinal row of staple supports and said second longitudinal row of staple supports is positioned closer to said anvil when said drivers are in said unlifted position. 13. The end effector of claim 8, wherein said firing member comprises a knife edge. 14. The end effector of claim 8, wherein said firing member comprises at least one inclined surface to lift said drivers toward said anvil. 15. An end effector for fastening tissue, comprising: a proximal end;a distal end;a first jaw comprising a cartridge, wherein said cartridge comprises a deck and a plurality of staple cavities, wherein said plurality of staple cavities are arranged in a first longitudinal row of staple cavities and a second longitudinal row of staple cavities, and wherein said deck is configured to support tissue;a first staple removably stored within said first longitudinal row of staple cavities;a second staple removably stored within said second longitudinal row of staple cavities;a second jaw comprising an anvil, wherein said anvil comprises a non-stepped tissue-engagement surface and forming pockets;a staple driver system, wherein said staple driver system is configured to lift said first staple and said second staple toward said anvil, wherein said anvil and said staple driver system are configured to cooperatively deform said first staple to a first deformed height and said second staple to a second deformed height, and wherein said first deformed height is different than said second deformed height. 16.
