Digital BW, The Print

I highly recommend trying to give away dead printers for parts first 
(look for Freecycle or forums like this).  

Second would be manufacturer take back programs like this one from 
Epson (I don't know details)

Third would be to find info on a local hazardous waste or electronic 
waste recycling day put on by your municipality or county.
