What is the most suitable printer for printing carbon copies?

By produce do you mean Generate? - gee i don't think anything short of a really complex print shop can do that (the carbon has to be inserted between the forms and glued together...) But any printer can print several copies of a form sou you can assemble them manually later (use the most lightweight paper you can possible find). If you mean PRINT ON (through) carbon copy forms, you want a dot matrix printer. They make a lot of noise but they have needles (or hammers) that push on inked tape and so can get through the paper and carbon the the underlying copy.
