To print a graph of a period of time, first use the mouse to
highlight the interval of interest.  Then press the <seismogram
button> (the button with a picture of a seismogram) in the upper
left corner of the screen.  This will cause a new window to
appear with a display of the highlighted portion of your data.

Next use the File/Print option to obtain a printed copy of
the event.  To create a file to share with someone else, use
the File/Save option.  

An alternative to File/Print is to press the <PrintScrn> button.
Then open MS Word and use the Edit/Paste button to paste the
screen dump into a word document.
