Juan Planck

1479-1484) was a fifteenth-century German cleric turned printer who became a founder of the printing business in Iberia.

[5] In 1477, Planck also began working with Pablo Hurus (with whose brother, Juan/Johann, he is not to be confused).

[6][7] Planck never had his own press and his name does not appear in any colophon, but a series of editions have been attributed to him such as Ethica ad Nicchomacum (1473), printed with Botel and Holtz, Vita et transitus sancti Hieronymi (c. 1476-77), printed together with Botel and Paul Hurus, or the Fables of Aesop (1482) with Paul Hurus.

[8] Planck may or may not be identical with the Johannes de Salsburga who worked alongside Paul Hurus in Barcelona, appearing alongside him in the colophon to a 1475 Barcelona edition of Perottus's Rudimenta Grammaticae.

(Little else is known about Johannes de Salsburga; another possible identification is with one Juan Gherlinc).
