There's something wrong with the way my brain is wired. I am by accounts an intelligent, capable, successful person, but I am completely unable to "read" comic books. I might as well be staring at a foreign language. When I'm trying to learn a technical topic, I thrive on dry reference material. Put a cartoon in and it's like running into a brick wall.
I don't know where I was going there except I feel like any time this comes up, I have to over-explain myself for not liking that book, because everybody loves that book and I will be burned at the stake for not regarding it as the greatest programming book ever written. It's just my personal experience, and I accept that I'm totally wrong about it, ok? Anyway, shorter version is that I had such a visceral reaction, any time I see "why_" mentioned, my reading comprehension reverts to that of a toddler.
If that's all irrelevant and the point you were making was more like "kids today don't know what PCL is", I am very familiar with PCL and print spoolers, but detached from any context that would suggest printers, they failed to take on any semantic value.
