The project cost of £60,000 has been reached thanks to a £15,000 growth grant, helping pay for a new professional printer and associated training.
The new technology replaces Howard's current labelling system and avoids having to outsource to Europe for plant labels.
Director Christine Howard said: "It was a two-year project and quite daunting at first, but we're really pleased we went for it.
"So far this season we've really started to see the results – increased orders from customers, some good feedback, and it's helping promote the Nursery and Suffolk generally."
Mark Reeve, chairman of the Eastern Agri-Tech Growth Initiative Board and Greater Cambridge Greater Peterborough Enterprise Partnership, added: "The labelling project presented by Howard Nurseries demonstrates the opportunity to support significant local business growth that will create new jobs and protect existing employment."
The Eastern Agri-Tech Growth Initiative is run by the Greater Cambridge Greater Peterborough Enterprise Partnership (LEP) with support from New Anglia LEP, Norfolk County Council, Cambridgeshire County Council, and the local authorities covering this area.
