In 'The Scottish Legal System' 1, the authors say that
The first printing press was introduced into Scotland in 1507, but it was not until 1541 with the printing of the Black Acts that it was applied to legislation.
However, the Records of the Parliaments of Scotland state that the Black Acts were not passed until May 1584.
