Final answer:
Controlled substance data on hard-copy printouts must be distinctly visually identifiable to enable quick recognition and reduce dispensing errors.
Step-by-step explanation:
The question is asking for the criteria by which "Controlled Substance" data on hard-copy printouts should be presented to ensure easy identification and differentiation from other data. The answer is that the data must be distinctly visually identifiable. This means that the controlled substance data should stand out in some way, such as using bold text, different colors, or a separate section on the printout. This is important to ensure that pharmacists and healthcare providers can quickly identify the controlled substance data, reducing the risk of errors in dispensing medication and adhering to regulatory requirements for tracking controlled substances.
