Claims (1)

[Scope of claim for utility model registration] A print head that prints on a medium, a driver circuit that controls the drive of the print head according to print data, a detection sensor that detects the position of the medium or print head at the print position, and a driver. In a printer that has a print timing circuit that temporarily stores print data sent to the circuit, and when it is determined that the medium or print head has reached the print position, prints by sending the temporarily stored print data to the driver circuit. A print timing pulse generation circuit that generates pulses synchronized with the movement of the medium or print head, a counter that counts the timing pulses and generates the print start position timing, and a quantitative print start position error that is unique to each printer. A printer characterized in that it has an absorbing depth switch.
