Why an href link is not redirecting to the proper target?

I have been trying to print a sample page in the browser by following the updated instructions but it doesn't work or make sense.

link to GitHub code

It says:

Print from your web page (user action) You can print from web doing a link in your HTML page:

Print from a web page visualized in an Android device web browser. Just embed in your page a link or a button:

a href="com.fidelier.printfromweb://$biguhw$Print From Web$intro$$small$Print small letter$intro$->$intro$->$intro$->$intro$$intro$$intro$$intro$$cut$$intro$"Test print from web/a

It doesn't work.
