Characters are placed into a printer queue and print at the selected speed. High-speed presets are available up to 600 lines per minute. Only visible printed characters produce sound; spaces are silent. Use TEST SOUND once if your browser has not yet enabled audio. The supplied printer recording is now pitch-raised and aggressively amplified/compressed for much stronger per-character playback.
Enter performs a line feed. Tab advances to the next 8-column stop. Text wraps automatically at column 80.
ASCII files are printed through the same character-by-character mechanism.
