Abstract
A printing drum (2), to which a stencil sheet having subjected to a stencil making process is attached, can be attached to and removed from a printer main body (1). A nonvolatile memory (25) is provided in the printing drum. The number of print products is stored in the nonvolatile memory as “Information on the use” of the printing drum. A control device (5) of the printer main body reads out “Information on the use” from the nonvolatile memory and stores them in a RAM (12) when the printing drum is attached to the printer main body. Subsequently, when printing is performed, information on the number of print products is updated. When the printing drum is removed from the printer main body, “Information on the use” is updated and written into the nonvolatile memory.
