Engraving was the term for setting musical scores in type for printing 
and publication. It was done in a variety of ways from actually 
engraving on a metal plate to musical typewriters. It was a very tedious 
and expensive process and required skilled craftspeople to make the 
engravings. As a result, a lot of music was never published or only 
published as reproductions of a copyists manuscripts and also 
contributed to the high cost of printed music. In later years engraving 
was often done overseas where labor was cheaper. In the digital age this 
is now done with software such as a Sibelius of Finale, but the term 
engraving persists even though I doubt anybody actually engraves music 
these days.

Wikipedia has a pretty good explanation 
( and Don Krummel's book 
Music Printing and Publishing is the classic reference in the history of 
music publishing.
