You misread the page. It says exactly what you got. Notice it is
showing eruby and erb examples. The erb example gives what you got.

<% print "hello" %> goes to stdout.

<%= "hello" %> is a short-cut for something like <% response.print
"hello" %> which may or may not be/include stdout.

So depending on how stdout is handled during building the template, <%
print "hello" %> may or may not work. In the examples on the erb page,
it shows it working for eruby but not for erb.
