If you print a lot, I think you'll find Command-P on the keyboard to be the most convenient, just as doing Command-S (to save work in progress) gets to be a habit. 🙂
The reason I said right-click to print does not make sense, is because the right-click is supposed to be the
contextual menu. What's on that menu is supposed to vary, based on what the cursor is pointing at or doing. So if you highlight a word in a text document, things like
copy and +look up in dictionary+ and +change font style to bold+ should be on the menu. If
print is on there, unless you want to print one word, that command applies to the whole document.
