A significant feature of dot matrix printers is their ability to print multi-part forms, such as invoices and receipts, which are often required in business settings. This capability stems from their mechanism that uses a print head to strike an ink-soaked ribbon against the paper, allowing the printer to push through multiple layers of media. This means that dot matrix printers can effectively produce carbon copies or multipart forms in one go, something that inkjet printers, which rely on a single layer of media, typically cannot do.

While inkjet printers excel in higher resolution and can produce high-quality images and graphics, they are not designed for multi-part forms. The printing speeds can vary, but generally, inkjet printers might be faster for single-page documents without multiple layers. In terms of size, dot matrix printers tend to be bulkier due to their mechanical components compared to the more compact designs of many inkjet printers. Thus, the ability to handle multi-part forms stands out as a defining feature of dot matrix printers.
