As his hometown lacked any printer shops, in 1816 Buchan went to Stirling to learn the printing process, becoming proficient enough to produce samples within a matter of ten days.
He established business as a printer in Peterhead in March 1816, with the support of the Earl of Buchan who recommended a friend to fund the purchase of the press.
[2] After this, he held a position in London from which drew a £150 annual income, but having compromised his health, he retired to Peterhead and devoted himself to the collection of Scottish ballads from oral sources, and their publication.
[1][2] Another collection made by him was published by the Percy Society, under the title Scottish Traditional Versions of Ancient Ballads (1845).
[1] Buchan also compiled a collection of folktales, and his manuscripts were known to John Francis Campbell who discussed them in his Popular Tales of the West Highlands.
