The first printer associated with Oxford University was Theoderic Rood. A business associate of William Caxton, Rood seems to have brought his own wooden printing press to Oxford from Cologne as a speculative venture, and to have worked in the city between around 1480 and 1483. The first book printed in Oxford, in 1478, an edition of Rufinus's "Expositio in symbolum apostolorum", was printed by another, anonymous, printer. Famously, this was mis-dated in Roman numerals as "1468", thus apparently pre-dating Caxton. Rood's printing included John Ankywyll's "Compendium totius grammaticae", which set new standards for teaching of Latin grammar.
