===Printers=== right|thumb|Epson LQ 850 dot matrix printer In 1961, Suwa Seikosha established a company called Shinshu Seiki Co. as a subsidiary to supply precision parts for Seiko watches. When Seiko was selected to be the official time keeper for the 1964 Summer Olympics in Tokyo, a printing timer was required to time events, and Shinshu Seiki started developing an electronic printer.<ref name="Kelly2006">{{cite book|last1=Kelly|first1=Jan Seaman|last2=Lindblom|first2=Brian S.|title=Scientific Examination of Questioned Documents.|date=2006|publisher=CRC Press|location=Hoboken|isbn=9781420003765|edition=2nd|page=202}}</ref>
In September 1968, Shinshu Seiki launched the world's first mini-printer, the EP-101 ("EP" for Electronic Printer), which was soon incorporated into many calculators. In June 1975, the name Epson was coined for the next generation of printers based on the EP-101, which was released to the public. The Epson name was coined by joining the initials EP (Electronic Printer) and the word ''son'', making "Epson" mean "Electronic Printer's Son".<ref name="CompHist">{{cite web|title=Company History|url=https://epson.com/company-history|website=Epson US|access-date=13 December 2016}}</ref> In April of the same year, Epson America Inc. was established to sell printers for Shinshu Seiki Co.
thumb|Epson HX-20 In June 1978, the TX-80 (TP-80), an eighty-column dot matrix printer, was released to the market and was mainly used as a system printer for the Commodore PET computer.

The company developed the Micro Piezo inkjet technology, which used a piezoelectric crystal in each nozzle and did not heat the ink at the print head while spraying it onto the page, and released the Epson MJ-500 inkjet cartridge for the Epson Stylus 800 printer in March 1993. Shortly after in 1994, Epson released the first 720 dpi colour inkjet printer, the Epson Stylus Color (P860A) utilizing the Micro Piezo head technology. Newer models of the Stylus series employed Epson's special DURABrite ink and used two hard drives (an HD 850 and an HD 860).<ref>{{cite web|url=http://www.allprinterreviews.com/epson-printers.html|title=Epson Printers - Unrivaled in Quality|access-date=16 August 2015}}</ref> thumb|Epson R2000 printer In 1994, Epson started to outsource sales representatives to help sell its products in retail stores in the United States. The same year, it started the Epson Weekend Warrior sales program.<ref>{{Cite web |date=2019-10-26 |title=Epson Printers Exceeds your Vision - Techspot Kenya |url=https://www.techspot.co.ke/epson-printers-exceeds-your-vision/ |access-date=2025-05-09 |website=www.techspot.co.ke |language=en-US}}</ref> The purpose of the program was to help improve sales, improve retail sales reps' knowledge of Epson products, and to address Epson customer service in a retail environment. Reps were assigned on weekend shifts, typically around 12–20 hours a week. Epson started the Weekend Warrior program with TMG Marketing (now Mosaic Sales Solutions), and later with Keystone Marketing Inc, then returned to Mosaic, and switched again to Campaigners Inc. on June 24, 2007 after the Mosaic contract expired. The sales reps of Campaigners, Inc. are not outsourced; Epson hired rack jobbers to ensure retailers displayed products properly, freeing up its regular sales force to concentrate on profitable sales solutions to value-added resellers and system integrators, leaving "retail" to reps who did not require sales skills. thumb|Epson R-D1 digital rangefinder camera
===Computers {{anchor|Personal computers}}=== Epson entered the microcomputer market in 1982 with the HX-20 (HC-20 in Japan), which is also the world's first notebook computer. It entered the home computer market with the QX-10, a CP/M-compatible Z80 machine. By 1986, the company had shifted to the growing IBM PC compatible market with the Equity line. Epson also manufactured and sold NEC PC-9801 clones in Japan. In the United States, it marketed the ActionNote line of PC-compatible notebooks from 1993 to 1996.<ref>{{cite journal | ref={{sfnRef|Emigh|1993b}} | last=Emigh | first=Jacqueline | date=June 7, 1993 | url=https://link.gale.com/apps/doc/A14017005/GPS?sid=wikipedia | title=Epson: ActionNote to compliment, not replace, NB series | journal=Newsbytes | publisher=The Washington Post Company | via=Gale OneFile}}</ref><ref name=stretch>{{cite journal | last=Lanctot | first=Roger C. | date=May 26, 1997 | url=http://www.crw.com/reports/speci039.asp | title= Growth a Stretch as Price Tags Plunge | journal=Computer Retail Week | page=43 | publisher=CMP Publications | archiveurl=https://web.archive.org/web/19990221002902/http://www.crw.com/reports/speci039.asp | archivedate=February 21, 1999}}</ref> Epson withdrew from the international PC market in 1996.<ref name=stretch /> The company still produces and sells PCs in Japan as of 2024.<ref>{{Cite web |title=パソコン |url=https://shop.epson.jp/pc/ |website=shop.epson.jp}}</ref>
===21st century=== thumb|upright|SureColor large format printer at Photokina, 2016 In June 2003, the company became public following its listing on the first section of the Tokyo Stock Exchange. Since 2017, the company is a constituent of the Nikkei Stock Average index. Although Seiko Group Corporation (f/k/a K.

In 2004, Epson introduced its R-D1 (the first digital rangefinder camera on the market), which supports the Leica M mount and Leica M39 mount lenses with an adapter ring. Because its sensor is smaller than that of the standard 35 mm film frame, lenses mounted on the R-D1 have a narrower field of view by a factor of 1.53. In 2006, the R-D1 was replaced by the R-D1s, a cheaper version with identical hardware. Epson has released a firmware patch to bring the R-D1 up to the full functionality of its successor, being the first digital camera manufacturer to make such an upgrade available for free.{{Citation needed|date=March 2008}}
In November 2011, Epson entered the smartglasses market under the Moverio brand. The BT-100 was the first consumer smartglasses with transparent optics, which were popular with drone pilots for providing a first-person view while still being able to see the drone in the sky.<ref>{{cite web|url=https://corporate.epson/en/about/history/milestone-products/2011-11-bt100.html|title=The Moverio BT-100|access-date=10 April 2025}}</ref>

==ESC/P== {{main|ESC/P}} To control its printers, Epson introduced a page description language, the Epson Standard Code for Printers (or ESC/P). It became a de facto industry standard for controlling print formatting during the era of dot matrix printers, whose popularity was initially started by the Epson MX-80.<ref name="Kelly2006" />

== Ink cartridge controversies == {{update-section|date=July 2023}} In July 2003, a Netherlands-based consumer association advised its 640,000 members to boycott Epson inkjet printers. The organisation alleged that Epson customers were unfairly charged for ink they could never use. Later that month, however, the group retracted its call for a nationwide boycott and issued a statement conceding that residual ink left in Epson cartridges was necessary for the printers to function properly.<ref>{{cite magazine |url=http://www.pcworld.com/news/article/0,aid,113112,00.asp |title=Epson Faces Consumer Suits |magazine=PC World |date=2003-10-24 |access-date=2009-07-30 |archive-date=2006-04-23 |archive-url=https://web.archive.org/web/20060423153454/http://www.pcworld.com/news/article/0,aid,113112,00.asp |url-status=dead }}</ref>
Epson designed ink to be left in the cartridges (having done so ever since the introduction of piezoelectric print heads) due to the way the capping mechanism worked. If the capping mechanism dries out, then the heads risk getting clogged, necessitating expensive repairs.{{cn|date=March 2025}}
Nonetheless, Epson America, Inc. settled a class action lawsuit brought before the Los Angeles Superior Court. It did not admit guilt, but agreed to refund $45 to anyone who purchased an Epson inkjet printer after April 8, 1999 (at least $20 of which must be used at Epson's e-Store).<ref>{{cite web|url=http://www.epsonsettlement.com/ |title=XO(R) Web Site Hosting |publisher=Epsonsettlement.com |access-date=2009-07-30 |url-status=dead |archive-url=https://web.archive.org/web/20071214061453/http://www.epsonsettlement.com/ |archive-date=December 14, 2007 }}</ref>
According to IDG News Service, Epson filed a complaint with the U.S. International Trade Commission (ITC) in February 2006 against 24 companies that manufactured, imported, or distributed Epson-compatible ink cartridges for resale in the U.S.{{citation needed|date=September 2014}} On March 30, 2007, ITC judge Paul Luckern issued an initial determination that the cartridges in question did infringe upon Epson's patents.<ref>{{cite web|url=https://arstechnica.com/tech-policy/2007/04/epson-wins-preliminary-ruling-against-aftermarket-cartridge-manufacturers/|first=Jacqui |last=Cheng |title=Epson wins preliminary ruling against aftermarket cartridge manufacturers|work=Ars Technica|date=9 April 2007|access-date=16 August 2015}}</ref>
In 2015, it emerged that Epson printers reported cartridges to be empty when in fact up to 20% of their ink remains. As in 2003, the company responded:
