And one that's been touched on here already - there are
print heads available that are resistant to organic-solvent
inks. They are used for labelling goods on the production line.

Expensive too - but not as expensive as starting your own
factory for making print heads.

[ Now I've said that, someone is going to tell us how they
dismantled their print head and made a lost-wax injection
moulding of the plastic parts in high-chemical-resistance
epoxy resin and re-installed the silicon wafer or piezo
crystal and it runs on marker pen refill ink...
    -  youze guys sure are ingenious ;-) ]
