An idea: click on the formula bar, highlight the entire formula, and
press CTRL-C to copy the formula into the clipboard. Then open MS Word
and press CTRL-V to paste. This will allow you to print the entire
formula.

As an alternative, if the formulas are _very_ similar and you want to
compare them character by character, copy the formulas to the clipboard
but this time paste them into Notepad. Notepad is a very handy, very
rudimentary text editor that does not perform a word wrap, so the
formula will be written out in its entirety with no line breaks.
