I presume you are not referring to an "a-type print" engine for a photocopier, and a Google search turned up nothing else even close. Thus I can only guess you have seen the word somewhere as a short form for ambrotype. The ambrotype, invented in the mid-1850's, also used the wet plate collodion process but the final image was converted to a positive one via a little trickery. Check Wikipedia for more.
