Printer

摘要

Disclosed is a printer. A printer of the present invention has: a printer body; a printer head movably mounted on said printer body for reciprocating with respect to said printer body; a sensor for detecting a movement of said printer head; head turnback position detecting means for detecting a turnback position of said printer head based on pulse signals output from said sensor; pulse resolution changing means for changing a resolution of the pulse signals from said sensor based on a detected result obtained by said head turnback position detecting means and generating a reference pulse signal for a printing position. The printer carries out a printing operation via said printer head as the printer determines the position of said printer head based on the reference pulse signal for the printing position.
