[M100] Brother M-1009 dot matrix printer, dip switch settings

[BiggRanger]

I have a Brother M-1009 dot matrix printer for my Tandy 200, but no 
manual for it. I've tried my best google-fu, but can't dig up anything 
but long dad links. Would anybody have any info on the dip switch 
settings for this printer?

Thanks!
Darren
