jaabc2ps could be used for mandolin and mountain dulcimer. There are a few details for this at http://www.guitarnut.com/abc/jaabc2ps.html#stringtab. The program is a bit out of date though.

Also for mountain dulcimer, I remember there being a python abc progam for this. I don't know if it still is developed but when I looked at it, there were a number of problems with it.
