Photostat vs. Photocopy — What's the Difference?

Key Differences
Photostat and photocopy, both terms associated with the reproduction of documents, have distinct historical and technical backgrounds. Photostat, a proprietary name, refers to an early 20th-century machine that made direct positive or negative images on sensitized paper through exposure to light. In contrast, photocopy pertains to a more modern method using light-sensitive photoreceptors and toner to replicate documents.
The technology behind Photostat machines is somewhat archaic by today's standards. When using a Photostat machine, an image would be projected onto sensitized paper, creating a duplicate. However, the photocopy process employs a drum that captures an image which then attracts toner particles, transferring them to paper to recreate the document.
Over time, the term "photocopy" has become ubiquitous in describing the act of copying documents, mainly due to the widespread adoption of xerographic machines, commonly known as photocopiers. Conversely, Photostat, while historically significant, has faded into relative obscurity as the technology became obsolete.
It's also worth noting the genericization of brand names. Much like how some brands become synonymous with their product category (think "Kleenex" for tissues), "Photostat" was once a prevalent term for copying. In modern times, however, "photocopy" reigns supreme, representing the action regardless of the machine's brand.
In essence, while both Photostat and photocopy relate to document reproduction, they symbolize different eras and technologies in the evolution of copying.
