From 1539, when John Hertfort was summoned from St. Albans, to the end of the reign of Henry VIII, we know of no provincial printing in England. But on the accession of Edward VI the extreme Protestants who had fled from England to the Netherlands, Germany, and Switzerland, came flocking back, and some of them seem to have stopped at Ipswich. Two, or perhaps three printers, all in the Protestant interest, worked there in the first few months of the new reign. The first of these, Anthony Scoloker, printed seven books at Ipswich in 1547 and 1548, and then went on to London. The second, John Overton, brought over with him from Wesel the text of Bishop Bale's Latin bibliography of the Illustrious Writers of Britain, printed there by Theodoricus Plateanus, otherwise Dirick van der Straten, and may or may not have printed at Ipswich two additional sheets, which he dated there 31 July, 1548.[56] The third printer, John Oswen, printed at Ipswich eleven tracts, mostly controversial, in or about 1548, and then removed to Worcester. On his arrival at Worcester late in 1548, or early in 1549, John Oswen obtained a special privilege from Edward VI for printing service-books for use in the Principality of Wales, and produced there three editions of the first Prayer Book of Edward VI and a New Testament. Besides these, from 1549 to 1553 he printed eighteen other books, mostly of controversial theology, calling himself in his imprints "Printer appoynted by the Kinges Maiestie for the Principalitie of Wales and the Marches of the same." On the accession of Mary, it being no longer safe to print Protestant theology, Oswen's press ceased working. At Canterbury in 1549 John Mychell, or Mitchell, who had moved there after producing a few books in London, printed an English psalter, "poynted as it shall be songe in churches." During Edward's reign Mychell printed at Canterbury altogether some twenty books and tracts, mostly more or less controversial treatises on the Protestant side. On the accession of Mary he ceased publishing till 1556, when his press was employed by Cardinal Pole to print his Articles of Visitation.
