- whereby pivoting of said cam, with said starting means, toward said platen pivots said link around said link pivot, which, in turn, moves said inking roller holder to move said inking roller over said types.
- 8. The label printing machine of claim 7, further comprising an elongated slot in said link, at which said link pivot engages said link, and said slot being elongated in a direction such that when said pivot lever has moved to said printing position, said link may slide along said slot, back toward said types, for reducing protrusion of said link.
