[Leica] OT: Laser printer cartridges

[Peter Klein]

Off topic, but maybe somebody knows. Does the actual composition of 
black laser printer toner powder vary from model to model?

I'm asking because... I recently replaced my 7 year-old Brother home 
laser printer because the drum wore out. At that point, it seemed 
reasonable to buy a new printer, which was not much more expensive than 
a drum kit. This left me with a nearly new OEM toner cartridge for it. 
The new replacement printer, of course, takes a different cartridge. My 
question is, would it be OK to empty the old toner cartridge into a 
suitable bottle and transfer it into the new printer cartridge, which is 
now saying "Toner Low." That might be less hassle than selling the old 
cartridge.

Old printer: Brother HL-5470 DW.  Cartridge: TN750 (3000 pages)
New printer: Brother HL-L2460 DW.  Takes cartridges TN830 (1200 pp) or 
TN830XL (3000 pp)

There are several other possibilities: use aftermarket toner powder in 
my OEM cartridge, buy an aftermarket "compatible" cartridge, or just 
suck it up and pay Brother's high prices.
