Mark 1-inch characters, codes with one printhead

摘要

For faster and easier data capture, many retailers require consumer packaged goods and food and beverage manufacturers to mark 1-inch tall characters and/or bar codes on secondary cases. Yet, the only way to do that with thermal ink jet technology used to be to stack two 0.5-inch-tall printheads together—a setup that can easily be knocked out of alignment by production line vibration, causing codes or text to be offset.
