Defold Printer or RichText

Yeah I took a look at the examples. I tried a simple line of text. I created a game object, and attached a gui to it. Attached to the gui was the gui script simply having:

local richtext = require "richtext.richtext"
function init(self)
richtext.create("Single line text with a dash of color By default left aligned.", 
"system_font")
end

Still nothing happened, I’m sure I’m doing something wrong…
