For inkjet cartridges, I don’t know, but, technically speaking, these cartridges get dry after the first time of use and their ‘needles’, that spray ink, become dirty. I had a bad luck washing the spraying mechanism after that.
LaserJet toners are not liquid at all, so they don’t dry out. They’re just powdered plastic particles that are attracted to static electricity created by lasers on the paper and are melted to the paper with a heated drum. Aside from energy use, laserjets are far superior to inkjets.
There’s a best before date?
That’s a good question
For sauce, yes.

EDIT: I don’t know about the laserjet toners.

I’m calling print cartridges HP Sauce from now on. Or, I would, if I had an inkjet or a HP, but that’s showbiz baby.
