Print drama before print was cool
LaserWriter Seeds
Xerox figured out modern printing early, and the comments are losing it
TLDR: Xerox PARC built the basic idea behind modern document printing years before it became mainstream, including the trick of letting the printer do the hard work. In the comments, readers are impressed but also stuck on the eternal drama of tech history: Xerox invented it, while others turned it into a business.
Before Apple made the LaserWriter famous, Xerox PARC was already living in the future. The article tells the wild origin story: researchers built a system that let a computer create polished documents and send them to a laser printer, even though the computer itself was way too weak to handle a full page image. Their workaround was clever and a little chaotic: move the heavy lifting into a special printer controller, then use software that let people see a page on-screen much like it would look on paper. In plain English: this was the seed of the modern "hit print and it looks right" experience.
But the real fireworks are in the community reaction, where history nerds and graphics geeks show up ready to argue over who deserves the crown. The loudest mood is a mix of awe and frustration: awe that Xerox had this shockingly early, frustration that so much of it feels like a "they invented the future and somehow still fumbled the bag" story. One commenter, Don Hopkins, zooms out into a classic deep-cut debate about page design systems, hinting at the old battle over how Xerox ideas evolved into Adobe and PostScript. That set off the familiar subtext readers love: was Xerox the genius, Adobe the winner, and Apple the one that made it popular?
The jokes basically write themselves. Readers are treating Xerox PARC like the tech world’s most tragic overachiever: invented tomorrow, monetized absolutely none of it, and left future companies to cash the checks. It’s equal parts admiration, nerdy one-upmanship, and "how did they not own the entire office?" disbelief.
Key Points
- •Xerox PARC researchers addressed the Alto’s inability to process full-page bitmaps by moving printing work to external hardware.
- •Ron Rider’s Research Character Generator stored font bitmaps in dedicated memory and controlled laser output for early text printing.
- •The integrated EARS system combined Ethernet, the Alto, the RCG, and the SLOT laser printer to remove Xerox’s printing bottleneck.
- •Charles Simonyi and Butler Lampson created Bravo to compose rich documents with mixed fonts, styles, and images.
- •Bob Sproull and William Newman developed the Press page description language so full-page document layout could be sent compactly to the printer controller.
