Where the technologies diverge
Ink and ribbon cassette printers apply marks on top of the cassette surface. UV laser systems etch directly into compatible cassettes. In histology, the practical difference is often durability through chemical processing and whether barcodes still scan after dehydration, clearing, and paraffin exposure.
- Ink/ribbon: consumable replenishment and drying considerations
- UV laser: no ink cartridges or ribbon swaps for routine marking
- Both still require validation with the lab's cassettes and protocol
- Compare after-processing scan results, not only bench demos
