Brothers are not technically laser printers since they don't use a laser. Instead they use an array of LEDs. For most things that's a distinction without difference, but I've noticed that my Brother printers run noticeably cooler than, say, an HP laser printer.
Pretty close guess. Actually it doesn’t matter if it’s leds or
lasers that activate the transfer drum to pick up the toner and
transfer it to the paper.
What is different is the chemical formulation and the temperature
that the toner powder melts and fuses to the paper. The old monster
HP printers like the IIIsi as an example had a 1000W halogen light
tube inside a 1 1/4 inch steel roller covered with a non stick
coating… this was the “fuser assembly’s” core. The hotter the
roller, the more pages you could print a minute.
Now that much heat makes for smell and isn’t “green” anymore so more
and more manufacturers are developing and using toner powders that
melt at a lower temperature. I suspect that you will see the same
problem start appearing in copiers as they try to green them up some
more too,
It’s really that simple. green does not always equal better
