Welcome to IWETHEY!

New Shouldn't possibly work as fast?
That is what I've been trying to impress upon you. Didn't I say really really fast a post or 2 above?

That band of metal is spinning around faster than you can see. But those hammer banks hit those letters at whatever moment as it spins by and chugs to the next line. That's the chugga chugga chugga noise going on.

From the human perspective that line printer has just printed that entire line instantaneously and has progressed to the next line. But from the microcode level you know there's a hell of a dance going on.
New Yes, but I was picturing the line matrix
Still impressive, but not nearly as frightening.

New Line matrix is easy
Line of data shows up into buffer. Map those points to pins that you're going to slam. Slam the pins. This is a simple bitmap manipulation. Move to next line. That is the simplest s*** in the world. Nothing impressive about it. I could code that in 20 minutes.

Compare that to having to figure out where those spinning band characters are versus what you are attempting to print and hit the hammers at the exact moment individually while those particular characters are spinning by. That s***'s mind-boggling. I'd have to take into account synchronization with the band. Then I'd have to know when a character was flying by at the micro second level. I'd have to take into account stepper motor timing. Oh, by the way, there were multiple bands. We had to change out the bands if we wanted different character sets.

Also, did you see the tape on the right hand side in that video? That is form layout control. There were series of signals you had to throw to the printer so it would go to a particular position on a form and those forms were controlled by those paper tapes. Paper tapes break easy.
New Me with hardware control is like me watching figure skating
I know what *I* wouldn't be able to do, but not enough to know what's hard for people who know what they're doing.

                         I had 2 in my office - (crazy) - (18)
                             Someone has to have video of it online - (drook) - (17)
                                 Starting point - (crazy) - (16)
                                     Something close - (drook) - (15)
                                         Seems that way but is not the same device - (crazy) - (14)
                                             The one I remember was definitely run closed - (drook) - (13)
                                                 132 characters. - (crazy) - (12)
                                                     This was definitely not print shop volume - (drook) - (11)
                                                         You were hearing the band spin - (crazy) - (10)
                                                             Hold on, mind blown - (drook) - (9)
                                                                 Yeah that was old technology that still blows me away - (crazy) - (4)
                                                                     Speaking of old mechanical tech... - (Another Scott) - (1)
                                                                         The lathe is an ancient tool, dating at least to ancient Egypt and known and used in Assyria - (boxley)
                                                                     What happens when something mechanical gets scaled up. - (static)
                                                                     Band printers were cool - (pwhysall)
                                                                 Shouldn't possibly work as fast? - (crazy) - (3)
                                                                     Yes, but I was picturing the line matrix - (drook) - (2)

                 Agree totally on the Brother printers. - (hnick) - (2)
                     If you'd replaced the rollers... - (InThane) - (1)
                         Undoubtably. - (hnick)
