Sorry Terry but this is an ableist idea.
For example, my parents get a visitor to print emails so that my Mum (who is bedridden and who can’t use an electronic device due to mental confusion) can enjoy reading them to my Dad who is blind. This gives them both pleasure.
You might argue that your blog posts aren’t aimed at my parents and you would be right, but I am sure that there are other examples of perfectly good reasons why people want or need to print your stuff.
If I do, I’m sufficiently web-savvy to copy it to a something that will print.
Why take away a sensible feature that you don’t know all the use-cases for?
(And I recall you got quite narked with an app that did that to you recently)
