Printed books are expensive, but they are worth it if you care about image quality. Every year the LUG yearbook gets a little smaller. This year for the first time the softcover version did not have enough pages to permit a full label on the spine. We'll see how much longer we can keep this up. I apologize for it taking me so long to get this done, but now it is done and the delay is in the past.

Try to refrain in the future..... I suspect he was tricked by the LUG feature of always doing a ?reply all?. I?m sure he thought he was replying just to the sender.

I was the lead system engineer for two high-speed laser printers sold by DEC, and I have spent a lot of time fussing with laser printers. The short answer is that toner is an extremely high-precision substance; the size of the toner particles is critical to the functioning of the imager, and toner is not generally fungible between brands. In 2025 I don?t print enough on my laser printer to make it worthwhile to mess with toner, and in making decisions like this I rate my time at $50/hour. So for myself, it would not be worth it. I?d sell the unused cartridge on eBay. But Brother toner will be the same material for all of their printers, so you won?t have to fuss with the deep settings if you put Brother toner from one cartridge into another. Toner is very dangerous if you inhale it. We?re talking Black Lung Disease level of danger. If you do this, wear a suitably high-quality respirator that is rated for the particle size. The printers whose design I managed used toner that had 30-micron particles. I took a quick look at the Brother printer specs and I?d guess that they use 15-micron particle sizes. For myself, I would use supplied air and not a respirator to mess with 15-micron toner particles. I always used a scuba-style breathing apparatus when I had to get involved with live 30-micron toner. Our company?s service technicians didn?t. I have no data on how many of them are still alive.
