Those that invest in the HP machine receive an ink and media kit bundled with it, which when printed and sold at current market rates, covers the cost of the Z6100 large-format printer.
Managing director Doug Gilbertson said he hoped the promotion would raise the profile of the machine and accompanying HP media.
He said: "HP's media is far more price competitive than many users may realise and, because it is naturally matched to the printer and ink, it offers exceptional print quality."
Substrates available through the promotion include HP Super Heavy Coated Paper, HP Universal Satin and HP Vivid Colour Backlit.
Gilbertson said that through the promotion, customers would not only get the Designjet Z6100 for effectively no cost, but would also "make an impressive profit on top".
The London-based reseller has also launched an online calculator to help customers forecast possible profit to be made from the media bundled in the deal.
