A printer has a feeding path for guiding a printing paper from and toward an opening of the printer. A cross-sectional shape of the feeding path is minimized to be sufficient to pass the printing paper through the feeding path. At least one resonator is arranged in the feeding path. The resonator has a case defining a resonant chamber and holes formed on the case along with the feeding path. The resonant chamber communicates with the feeding path through the holes. Noises such as impact sound generated by a printing head of the printer are silenced by the resonator at frequencies around a resonance fequency of the resonator, and further silenced by the area reduced portion of the feeding path.
