Abstract
A laser label printer for use with a laser markable medium includes a laser-diode fiber-coupled to an optical train, which includes a focusing lens for focusing the radiation on the medium. The focusing lens is traversed across the medium, with incremental motion of the medium between traverses, for line by line printing of the label. The printer includes a feature for protecting the focusing lens from contamination, and self-diagnostic and adjustment features.
