Abstract: A printer-utilizing apparatus is disclosed herein, which decides automatically upon power throw whether the apparatus is in print mode or non-print mode and effects initializing of the printer and auto paper feed if the apparatus is in print mode, but does not conduct any printer operation such as initializing and paper feed, if the apparatus is in non-print mode. More particularly, the apparatus prevents unnecessary DC power consumption which otherwise would occur in a compact DC-powered printer apparatus and, when in print mode, conducts printer operations such as initializing of the printer and paper feed as well as notifying easily and clearly the operator that the apparatus has been turned on.
