He has been called a "stationer of dubious reputation"[1] who was connected with some of the "bad quartos" and questionable texts of Shakespearean bibliography.
[2] He was the son of a William Millington, a "husbandman" of Hamptongay, Oxfordshire, and was apprenticed to a Henry Carre for a period of eight years, beginning on St. Bartholomew's Day (24 August) in 1583.
For a time he was in partnership with fellow guild member Edward White; their shop was located, and their title pages specify, "at the little north door of Paul's at the sign of the Gun."
Millington's business was at the lower end of the publishing scale in Elizabethan England; he printed many ballads, including some by Thomas Deloney.
The major outbreak of bubonic plague in London in 1603 might not have been coincidental; printer Peter Short died in 1603, while publisher William Ponsonby passed on in 1604.
