Documation

Documation was an American Stock Exchange-listed computer hardware manufacturer founded in 1969 in Melbourne, Florida that went public in 1976. They made (punched card) card readers 
used in some American elections 3 decades later. They also produced Impact Line printers.
In late 1980, Storage Technology Corporation (STC) acquired Documation, which was subsequently spun off, and those companies which subdivided from it, most of which use Documation-like names, no longer manufacture computer peripherals.
Documation was described as "a financially troubled printer manufacturer."
IMPACT Line printers.
Documation's "IMPACT 3000", named for its 3,000 lines per minute rating, was followed a year later by the 3,800 LPM "IMPACT 3800".
A 5,000 lines per minute printer was introduced in 1986, by which time the company was operating under the name StorageTek Printer Corp. Like earlier impact printer models, it is manufactured in Florida. At the time of the Series 5000's introduction, the company said that "impact printers dominate 85 percent of the market." 
The company's laser printers are rebadged from Siemens.
Documation's Burroughs-rebadged printers.
Four Documation printers, rebadged by Burroughs as DOC 2000B, DOC 1800B, DOC 1500B and DOC 1250B were introduced in 1978.
Per their names, they were rated at "2,000-, 1,800-, 1,500- and 1,250" lines per minute, when using 48 character ASCII.
Card readers.
Among the card readers made by Documation for minicomputers in the 1970s were:
Their card readers have been used in elections, including the 2000 "Chads" election in Florida.
End-user market.
In late 1977 Documation successfully entered the end-user market. They initially focused on selling card readers to end-users; their model 6501 is IBM-compatible.
They subsequently added line printers to the equipment they sold to end-users.
Storage Technology Corporation and thereafter.
By 1992, the name Documation was no longer affiliated with Storage Technology Corporation in the US, but the latter still owned two Documation-named subsidiaries, one in France and the other in UK.
Ubeo, DOCUmation, Documation Inc.
The New York Times (adding "Inc") continued earnings and other coverage in the 1980s and early 1990s.
Ubeo Business Services and DOCUmation are regional companies somewhat related to the original Documation that had been acquired by StorageTek.
"Documation Inc" is covered by Bloomberg;
DOCUmation is a name that came into being in 1997, post-Storage Tek. At that point, neither company manufactured card readers or printers. Their niche is service and distribution of printers and duplicators/copying machines.
Another "Documation" is named "Documation, LLC" (founded 1994) and is based in Wisconsin. Their focus is described by Bloomberg as "print and digital media solutions ... direct mail marketing ... and graphic design."
Ubeo was a breakaway from DOCUmation, which was formed in the late 1990s by a merger of two San Antonio, Texas companies.
Before their May 2017 split they were known as DOCUmation of San Antonio
Ubeo was acquired by Sentinel Capital Partners in 2018.
DOCUmation acquired DocumentWorx November 2018 and renamed it DocumentWORKS.
