The story
Dymo Industries, Inc. was founded in 1958 to produce handheld tools that use embossing tape. The embossing tape and handheld plastic embossing labeler was invented by David Souza from Oakland, California.
Dymo was acquired by Esselte in 1978, and battery-powered printers became a major product after 1990. On June 1, 1998, CoStar Corporation, the manufacturer of the LabelWriter brand of thermal label printers, was acquired by Esselte Office Products. Although CoStar remained independent at first, it would later be folded into Dymo, initially as Dymo-CoStar, and later simply as Dymo, dropping the "CoStar" moniker altogether.
The Dymo Corporation would later be sold to Newell Rubbermaid in 2005.
