HP printers address need for speed

HP claims to have a five-year US$1.4 billion investment behind the range, but believes the pay-off will be in its ability to scale the new technology across a broad range of home, office and commercial printers and applications.

Enhancements to image quality and print speed are a result of newly developed technology that places 3,900 nozzles on a single printhead. The components are fabricated as one unit, and this, as well as the increased nozzle density improves the accuracy of ink drop placement and increases the area that can be covered with each pass of the printhead - thus producing faster, high-quality prints, HP claims.

If you've ever been irked by a printer stopping mid-page due to lack of ink, the new HP printers will please, as they are designed to avoid such waste and will not start the print process unless there is sufficient ink to complete the page.

New inks and photo paper
The speed and quality theme has also been carried through to new HP Vivera ink formulations. The six  HP02 ink cartridges used in the new Photosmart 8200 and 3000 series have been designed specifically for the 'stop-start' nature of home photo printing. A pumping system recirculates ink to eliminate air bubbles when priming the printhead without flushing or wasting ink. According to HP, the inks sport better fade resistance properties and they are also colour coded to make replacement a simple process.

New HP Advanced Photo Paper has been developed to dry instantly, so high-speed prints will not smudge or scratch. The backside of the photo paper is barcoded, so the printer will not activate if the paper is loaded upside down. This same Auto-Sense techology also notes what type of paper is being used and selects the print settings to optimise print speed and image quality.

Some of the first 'hero' products Australians will see based on the new technologies include:
