Towards the end of the commercial popularity of typewriters in the 1980s, a number of hybrid designs combining features of printers were introduced.
These often incorporated keyboards from existing models of typewriters and printing mechanisms of dot-matrix printers. The generation of teletypes with impact pin-based printing engines was not adequate for the demanding quality required for typed output and alternative thermal transfer technologies used in thermal label printers had become technically feasible for typewriters.
IBM produced a series of typewriters called Thermotronic with letter-quality output and correcting tape along with printers tagged Quietwriter. Brother extended the life of their typewriter product line with similar products. DEC meanwhile had the DECwriter.
The development of these proprietary printing engines provided the vendors with exclusive markets in consumable ribbons and the ability to use standardised printing engines with varying degrees of electronic and software sophistication to develop product lines.
Although these changes reduced prices - and greatly increased the convenience - of typewriters, the technological disruption posed by word processors left these improvements with only a short-term low-end market. To extend the life of these products, many examples were provided with communication ports to connect them to computers as printers.
The increasing dominance of personal computers, desktop publishing, the introduction of low-cost, truly high-quality, laser and inkjet printer technologies, and the pervasive use of web publishing, e-mail and other electronic communication techniques have largely replaced typewriters in the United States.
As of 2009, typewriters were still used by some U.S. government agencies. As an example, it was reported that in 2008 New York City purchased a few thousand typewriters, mostly for use by New York Police Department, at the total cost of $982,269; another $99,570 were spent in 2009 for the maintenance of the existing typewriters.
