The inkjet here is color,  but I haven't bought any supplies for it and may or 
may not get around to doing so.  The laser is nice but while it's on the lights 
flicker as the heater in there draws some nontrivial power.  I can see where 
the dot matrix would be handy for multiple-part forms if I used any.  I have a 
whole box of 2-part no-carbon around someplace,  if I ever decide that I need 
to do invoices or something,  but that's not real likely.  It's also handy for 
index cards and I even have some rolodex cards for it that I ran through there 
at one time.

It's actually kerosene and some heavier stuff,  and the kerosene is probably 
what acts like a solvent for a lot of things,  but that other stuff that gets 
left behind is what causes problems.  I know of one instance where that got 
sprayed on a printer ribbon and much more life was gotten out of that ribbon 
but then a new printhead was needed afterwards.
