If you select just the chart prior to printing, just the chart will
print. Any text boxes will not print if they are floating above the
chart in the drawing layer.
To put the text box into the chart, select the chart before adding it.
In fact, you can select the chart and just start typing, and Excel will
insert a textbox in the chart with the text you're typing. Select the
chart, press the = key and click in a cell, and the text in the textbox
will be linked to the cell.
