I heard from someone making conductive inks and they don't sell it to
public. They want to sell ypou a massive machine that uses that ink,
instead.
As far as floor wax goes: not a good idea. Stuff dries out and clogs
up a printer. Solvent? Ammonia, another alergenic chemical taht will
make you look like a spotted owl. Bottom line is: no conductive inks
are available on the market. Yet although they are available to
select customers. People print DNA's, resistors but we have no access
to these technologies.
Screen printing conductive material? Probably the same situation.
