PURPOSE:To eliminate consumption of unnecessary ink, toner, etc., on an overhead projector(OHP) sheet being, for example, impossible to tamper and to provide means for enhancing convenience of a color printer of this type having a tamper function resistance. CONSTITUTION:The color printer comprises a unit 5 for deciding a type of a record sheet to turn OFF a tampering function by a switch 6 when the sheet is decided, for example, to be an OHP sheet being originally impossible to tamer by the unit 5 and for forming a new functional presentation system for sound/video for the OHP. |
