Unlike other web browsers Google Chrome tries really hard to annoy you by not allowing you to customise the toolbars in YOUR browser to work the way you want. While there is no way to insert the missing print button at the left end of the Chrome toolbar toy can add it at the right end of the toolbar. That part of the toolbar is where Chrome displays extensions and fortunately there are a selection of extensions that various people have created to add the print button that Google were to slack to add to the browser themselves.
Searching for "Print Extension" in the Extensions tab within the Chrome web store displays a variety of alternatives, the simplest of which is the one called Print Extension.
