Question

you examine a document that clearly has toner on it. what should you look for next to get more information on the serial number of the printer that made the document?
trash marks
pins
ink
microdots

Explanation:

In forensic analysis related to documents with toner (like laser - printed documents), microdots (also known as printer dots or toner particles with encoded information) are used to identify the printer's serial number and other details. Trash marks are more about leftover marks from printing errors, pins are related to other printing mechanisms (not for serial number info), and link is not a term related to this context. So the correct option is Microdots.

Answer:

Microdots
