Possible to have a Text file viewer with "print" button

This is a continuation of a issue that came up as part of a different, previous thread:
https://www.experts-exchange.com/Web_Development/Web_Languages-Standards/PHP/Q_24769808.html#a25481030

I have hundreds of text files on my webserver.  These are plain-text files that come from a legacy system.  I have a script that via pull-down menus allows the building and subsequent selection for display of the text files.

Depending on the browser, the user gets or does to get a menubar or print button (e.g. Google Chrome presents neither regardless of the toolbar or menubar setting in the code.

Does anyone know of a way to open a window where the user would be presented with a window that included a optional print button that allowed them to view, and the optionally print the text file being viewed.

We got close but not quite there from the other thread.  May not be possible.  Here is the sample code/webpage:

(the default selections will produce a sample text file).
