As Dick Sullivan states in his 'Book of Modern Carbon Printing':
Today you may hear people who are apparently totally ignorant of the history of photography referring to digital prints as "carbon prints". These are not real carbon prints, but rather mechanical prints, made from inks that are carbon based, and printed out of an inkjet printer. Sometimes these same inkjet prints are referred to as "pigment prints", which historically, especially in Eastern Europe, was the preferred name for carbon prints. The great Czech photographer Josef Sudek called his carbon prints "pigmente" prints. There is currently a very annoying trend, annoying at least, to the photographically literate, of renaming inkjet prints. People are using terms like giclee, piezography, Cone, pigment, carbon, and so on to describe inkjet prints, and are also appropriating two names that have a long and revered history: "pigment" and "carbon".
