I don't know what's in the printers ink and I hope it's not lead but your thinking on the right scale.
Paper is made from trees and trees contains the mineral silica. This is why paper can be used for serious edge endurance testing (used to check quality of knife steels heat treating, blade geometry and sharpening techniques by industry)
Paper has abrasive qualities and will dull hard steel.
Silica is why even carbide saw blades get dull cutting wood.
