What Is a ‘Print’ in the Context of Dark Pool Trade Reporting?

A 'print' is the term used for the public reporting of a completed trade that occurred in a non-public venue, such as a dark pool. Because the execution is non-public, the trade details ▴ price and volume ▴ must eventually be reported to a public tape or reporting facility, often with a time delay, to ensure some level of post-trade transparency.

This public record of the transaction is referred to as a print.
