I want to print only the text I have selected in Safari. But I don't find the way of doing this. Neither I am able to make this from Word or PowerPoint.
Essentially, Apple has not provided this function, for whatever reason. There is a third party service that will apply to Cocoa-based apps. Being that Office is carbon-based, I don't think the service will work there, however Office does have the function built-in (see attachment).
