The innovation, launched by book chain Blackwell yesterday, removes the need to order a hard-to-find novel, or the wait to buy one that has sold out.

Even out-of-print works can be printed off in minutes.

The Espresso Book Machine will also benefit aspiring novelists who can walk in to a shop with a CD of their work and have their book professionally printed in minutes.

The cost of buying a book will be generally the same as if it were in stock.

Currently there are 400,000 books ready to be be downloaded. Blackwell hopes that by summer, one million will be available.

It has bought one of the machines for its store on Charing Cross Road in Central London, but if it is a success then more could appear at shops across the country.

The machine, which resembles an industrial photocopier and printer, prints 105 pages a minute, or one book every five minutes or so.

Blackwell's aim is that the customer will be able to browse a catalogue in a kiosk next to the machine then press 'Make Book' and watch as their novel is created.

First the cover is run off, then the pages are printed and collated.

The pages are then clamped and glue applied to the spine. In the final stage, the pages are stuck to the cover before being trimmed to size from A4. The completed book then pops out of a slot in the side of the machine.

'With the Espresso Book Machine you can order it and have it in your hand within a few minutes. Having books printed on-demand also reduces the carbon footprint and cuts down on the number that are pulped or sent back.'

Out-of-copyright books will be sold at 10p a page, meaning a 300-page book would be £30, although Mr Hutchings hopes the cost will come down.

All other books will cost the same as if they were bought off the shelf.
