OK, I'm struggling with how to respond to Dave McGuire's response, in this otherwise uneventful discussion thread, on the NeXT laser printer and how or if it is related in some ways or not, to other laser printers of the era. I've decided, to not say too much, and to not say it at length. First, as a personal matter, I'm sorry if Dave McGuire took my post in some kind of personal way, I apologize to him. I had no idea, that sort of personal response from him was at stake, regarding some set of laser printers, or my choice of words. The technical issues and histories about these printers, the subject of the discussion thread, are sufficiently noted for more information to be found by anyone interested, for their purposes. And, in looking at posts after Dave's, I *strongly* suggest reading more about what "a Canon SX print engine" means. It does not mean a ready-to-go printer, it means something as Dave discusses. The printers in discussion are not identical, and again homework can be done to determine their differences and where they share components in common - that being my point. Otherwise, I don't know about NeXT machines and printers, so I can't add further to that discussion. But Dave brings up a number of other things, which I don't believe are limited to this particular thread and subject. I see he feels strongly about them. But for many reasons including good-will discussion, I will not post responses to those things. Herb Johnson -- Herbert R. Johnson, New Jersey in the USA http://www.retrotechnology.com OR .net
