How can I print mirror image of my manuscript? -

I want to publish books from manuscript. My press man asked me to send him the print out of the document in the format of mirror image i.e. reverse mode to be done in butter paper. Can anyone tell me from where do I do the mirror image print and how much will it cost?

Use any photo editing software... Adobe photoshop can be used for that... Also you can use FLIP HORIZONTAL option in nero image edit which comes with nero burning software.
