This isn't true.  ESC E will formfeed if and only if there has been
some output or movement on the page.  Two ESC E's in a row do not do the
same thing as two formfeeds.

It is proper and prudent to begin and end each job with ESC E.  Just
make sure that nothing gets sent (not even a newline) between jobs.

For example, if the end of a job code looks like this:
	echo "^L"
and the beginning of the next job starts with ESC E, then you
will get a blank page.  This is because the echo will send a
formfeed *and* a newline.  The best way is to start and end
each job is with the equivalent of:
	echo "\033E\c"
