Beeper
EasyCoder PX4i Bar Code Label Printer User's Guide (Fingerprint Version)
The beeper acknowledges that an error has occurred or a key has
been pressed. The Intermec Fingerprint programming language
allows the key acknowledge signal to be turned off. The
frequency and duration of signals can be specified. Thus, it is
possible to create different signals for different conditions or even
to make the printer play simple melodies!
