The print layout removes navigation, interactive controls and this longer guide. It keeps the reference, the source website and the timing reminder. Your browser may add a date or page URL in its print headers; switch those off in the print dialog if you prefer a simpler copy.
What is included
The chart groups the 26 Latin letters, ten digits and supported common punctuation. Each character has a written dot-and-dash pattern and an audio button on screen. The paper copy is a reference, not an audio lesson or a complete radio operating guide.
The International Morse table differs from historical American Morse and from language-specific extensions. If you need Ñ, Arabic letters or another convention, use the appropriate reference rather than adding an unlabelled signal to this chart.
Use the chart without depending on it
For checking a message, look up each character and preserve the gaps. For learning, attempt the answer with the chart covered, then use it to correct a mistake. Looking at the chart before every audio prompt can hide which rhythms you actually recognize.
A simple classroom activity is to choose six letters, write five short groups and exchange them with a partner. Keep an answer key. Ask the other person to mark missing spaces separately from incorrect dots or dashes: they are different kinds of error.

Keep each group intact. In the second example the slash separates two words; it is not sent as a punctuation character.
Remember the boundaries
Inside a character, a short gap separates its elements. A longer gap separates letters, and a longer one again separates words. On the printed sheet, adjacent dots and dashes form one character group. In the site’s text examples, one space separates letters and a slash separates words.
For example, ... is S; . . . is EEE. A chart cannot recover missing gaps from a source that has already joined every symbol together. The decoder guide shows how to diagnose that problem.
