I need to add a [print listing] function to a classifieds script (Bos Dev Classifieds). When a visitor views a listing on the classifieds, they should get an option to click on a [print listing] link. This should open a new page with a document ready to be printed, and which automatically goes to the visitor's printer. See image included.
Please note that only when the modified script is tested by me after fresh install will the fee be paid (this won't take more than two days). All coding must be properly commented.
