""Knowledge" ain't quite the same as actual experience..."
Knowledge can come from reading a book, speaking to a person in the know, etc. or actual experience
You might have knowledge of something without experience but you certainly can have knowledge
from actually doing it yourself, just saying..................................
There's no doubt printing is easier with a PC today (I use both), MACs have their issues, more than
just printing, but that's another subject.
I believe what you meant to say is Reading about it isn't the same as actually doing it, but maybe I'm wrong.
