I don't think it depends on color, there seem to be differences between  
the black ones as well.
We had someone here selling refills a while ago, maybe he is still here  
and can offer advice or even product.

Generally i would tend towards the original cartridges rather than  
remanufactured ones or even refilling, i had bad luck with those. Ebay is  
a good source for original carts that are past their use by date but still  
work fine. I am told good refill toner is just the same, but i'm still  
reluctant. I used old copier toner of which i have lots and lots of in HP  
IIID carts, and it must be very different (finer maybe). It would apply  
way too much to the magnetic transfer roller, and i had to completely  
remove those "spacers" for the scraper. It will work just fine for text  
prints now, but not so good for PCBs.

Anyway, it would be interesting if someone knows a bulk toner that works  
well, but it may still not work the same in all printers.

  I've measured melting points for two toners, the original
toner in my HP LaserJet 6L, and the eBay toner I used to
refill my Samsung ML-1710.

  They don't abruptly transition from solid to liquid, but
become soft and waxy, then sticky, then  gooey, so "melting
point" needs clarification.

  The HP toner could be smeared with a hot iron at 103+/-3
deg. C.  The refill toner smeared at 99+/-2 deg. C.

  There's a decorative metallic transfer film you can iron
on to laser-printed text.  I measured the temperatures needed
to transfer: 110 +/- 3 deg C for the HP, and 81 +/- 3 deg C
for the refill stuff.

  The refill toner I used was from TonerKits on eBay--
cheap, great service.  I just poured it in & prints as
well or better on paper than the original. No differences
for toner transfer noticed.

  I've no idea how suitable it is, but I have 1,4Kg of
Toshiba T-6560 toner!
