As far as I can tell there are no properties or methods available in JavaScript, or basic field parameters that will flip either a field value or a page for printing. But there are some options.
1. For the special font - I assume this is a flipped font. You can't change the order of the actual field value, or as you've seen, it won't work correctly in a calculation. To fix this, reverse the text the format event. That way it's only displayed flipped.
2. This is something that could be more easily done with an Acrobat plug-in. Such a plug-in could flip text in a specific field. or flip an entire page for printing.
3. There actually is a way to do this with JavaScript using an undocumented function. However, it only works with the standard Type 1 fonts. This method is a way to show a field input or calculation result flipped.
