Visitors to the Trafalgar Square gallery can choose from 900 of the 2,300 pictures it holds for instant printing on a HP DesignJet 5500PS wide-format printer.
The move to digital print has allowed the gallery to offer more reproductions of its paintings to the public, with the added benefit of them being truer to the originals than litho.
By the beginning of next year the gallery plans to have all its pictures available and to begin offering prints on a range of different papers.
