Digital BW, The Print

Please excuse this as a newbie question, I have been reading for a couple
of weeks now and still have not figured it out and thought it was time to ask.

What exactly does DSS and DDS stand for? I understand the problems/
symptoms to be a green shift and clogs in the print heads and that they
are usually related to CIS but have been unable to figure out what the
letters mean.

thanks,
