I've used conductive paint a few times and the stuff I'm used to is basically silver particles suspended in a thin lacquer, although you can get thicker version, including spray on versions, designed for spraying rf shielding onto insides of boxes.
The biggest problem with printing will be the size of the silver particles, followed by the problem that in the thin lacquer version at least the silver will settle in the jar and need significant shaking to mix it up prior to use.

And yeah soldering to it would be a bit of an issue, it can be done but it has basically zero mechanical strength, and would burn off given a chance. Another bonding option would be conductive epoxy, although it's slower to build obviously, and a little less reworkable.
