The method includes reading data included in a first segment of a packet divided into multiple segments and issuing a command to a memory controller that causes the memory controller to shift and write a subset of the read data to a memory coupled to the memory controller. Further, users who submit information that is received are identified and the printed results are stored at storage locations that differ for each user.
