Final answer:
Dot matrix paper produces sharper photocopies than standard grid paper, providing a clear advantage for producing high-quality copies of designs or illustrations.
Step-by-step explanation:
An advantage of using dot matrix paper over standard grid paper is that it produces sharper photocopies than standard grid paper. This can be particularly useful for creating clear, high-quality copies of designs or illustrations that have been drawn using the dot matrix as a guide. Unlike heat-transfer papers that do not require ink, or considerations of expense and availability, the enhanced photocopy quality is a distinct benefit of dot matrix paper, especially when clarity and precision of copies are paramount.
