"... with Brother lasers is the toners isn't re-fusable ..."

Actually I think the problem is as someone else has suggested, i.e. that the 
required fuser temp is much higher. I have a Brother MFC-8500, probably 
about 10 years old now, still works fine but not very well for TT. Prints 
look fine on paper, even for large dark areas, but it's hard to get the 
toner to stick to a copper clad board and the toner isn't dense enough to 
completely block out the etch acid. Same problem making transparencies for 
photo resist masks.
