ABSTRACT:
In a thermosensitive stencil printer, a sensor responsive to the temperature of a thermal head and at least either of a sensor responsive to the temperature of ink and keys for entering a desired image density are provided. Cutting energy to be applied to the head is controlled on the basis of ink temperature and head temperature, thereby maintaining image density constant without regard to changes in ink temperature. The density of a printing is easily variable to desired density.
