Even if you’re not a graphics professional there will always be some documents, such as colourful posters, design proofs & large charts & diagrams, that work much better in A3. Booklets, too, can be created by printing on both sides of A3 & folding in half. & that’s why the C821 is so useful. There’s no need to buy a dedicated, bulky A3 printer & no need to pay for the services of a high street print shop. One printer does it all. Not only can the C821 can print all your routine black & white A4 documents at speeds of up to 32 pages per minute (ppm), but it performs at an impressive 22 ppm in full colour. Even in A3, it still prints at a highly capable 17 ppm in black & white & as fast as 12 ppm in colour. & that’s not all. Because it comes with 256MB RAM, expandable to 768MB, an optional 40GB internal hard drive, & a powerful 700 M Hz processor as standard, you can work with large & complex documents as easily as small & simple ones.
