Apparatus for storing and maintaining printing-associated information updated during the operation of the printing apparatus in a non-volatile storage unit
A writing-back task unit alternately performs writing-back of data of a second storage unit in two storage areas of a non-volatile memory according to a flag value of an updating flag. At this time, a counting process of a counter for obtaining a count value according to written-back data amount is performed. At a power-on time, it is determined whether or not all the counters have writing-back completion values. When all the counters have the writing-back completion values, if the updating flag=1, the data of the first storage area are written in a first storage unit of a RAM. On the other hand, if the updating flag=0, the data of the second storage area are written in the first storage unit of the RAM.
