摘要： A printer includes a system for automatically adjusting the drive voltage of a print head according to a predetermined rank characteristic of the head. This is accomplished by initially producing a reference signal along a signal line. The reference signal is delayed by a delay circuit by an amount corresponding to the rank characteristic of the print head. The delayed reference is then compared to the reference signal thereby resulting in the detection of the delay time therebetween. A control signal is subsequently generated that corresponds to the delay time. The control signal is connected to a print head driver through the signal line so that a drive voltage may be generated during a subsequent time interval, the drive voltage corresponding to the rank characteristic of the print head.

摘要： A manual printer includes a head unit. The head unit includes a recording head, a running roller and a projection coupled to a housing via a universal joint. The head unit can be tilted relative to the housing. The position of the head unit relative to a recording medium P is maintained even if the housing is tilted in any direction. A gap and an angle between the recording head and the recording medium P can be fixed which enables a stable printing operation.
