Abstract:
An object of the present invention is to suppress a printing apparatus from becoming unavailable due to the life of a nonvolatile memory ending. The present invention is a printing apparatus including: a volatile memory; a nonvolatile memory in which a rewrite of data is performed in units of blocks and whose number of times of rewrite has an upper limit; and a management unit configured to manage a use of the volatile memory and the nonvolatile memory as a spool buffer temporarily storing print data, and the management unit limits the use of the nonvolatile memory based on an estimated life of the nonvolatile memory, which is different from state information indicating a state of a defective block of the nonvolatile memory.
