akkarin writes in about a study reported at Ars Technica on how accurate ink-jet printers are when they report that cartridges are empty. Not very, it turns out. Epson came out on top of the study (and Ars rightly questions how objective it was, given that Epson paid for it), but even they waste 20% of the ink if users take the printers' word for when to get a new cartridge. On average, the printers in the study wasted more than half the ink that users bought.

netbuzz writes in to note that some early adopters of Microsoft Vista are reporting problems with Vista's implementation of IPv6. An example:"'We are seeing a number of applications that are IP-based that do not like the addressing scheme of IPv6,' says one user. 'We will send a print job to an IP-based printer, and the print job becomes corrupted. We're seeing this with Window's Vista machines. When IPv6 is installed, this happens without fail. As soon as we remove IPv6, all of our printer functions return to normal.'"

Yet another Anonymous Coward writes to tell us about a piece up at the NYTimes on the (lack of) longevity of photos printed on inkjet printers. As the article's title says, somewhat alarmingly, "It isn't that images fade, it's that they can vanish." The problem is actually more nuanced than this; it's that no-one has a reliable and standardized way of testing inkjet prints for longevity. From the article: "The life of color inkjet prints has also been hindered by the origins of the technology, which was mainly intended for printing things like pie charts, said Nils Miller, a scientist at Hewlett-Packard. 'The initial emphasis was, how do we get bright colors on plain paper," Dr. Miller said. "Permanence was not really on the radar screen yet.'"

scott3778 writes "Xerox said on Wednesday that its scientists have perfected a new method for printing hidden fluorescent wording using standard digital printing equipment. According to the company, the discovery paves the way for customers and businesses alike to add an additional layer of security to commonly printed materials such as checks, tickets, coupons, and other high-value documents. The hidden fluorescent words and letters show up only under ultraviolet light, said Reiner Eschbach, a research fellow in the Xerox Innovation Group, and the co-inventor of the patented process. What's more, the method for printing them doesn't require the use of special fluorescent inks."

PetManimal writes "Mike Elgan has had it with useless lights on gadgets and computers. He singles out the Palm Treo and the Dell XPS gaming laptops as being particularly bad with the use of unnecessary lights, and also cites the plethora of LEDs on desktop PCs and peripherals. 'My PC and other computing equipment make my office look like a jet cockpit. I have two LCD monitors, each of which has two indicator lights that flash even when the PC is turned off. The attached sound control has a light on it. My keyboard has multiple lights. The power cord has lights, the printer has lights, and the power button is illuminated. My cable modem and Linksys router flash like crazy all the time. Together, these useless lights create a visual cacophony of blinking, multicolored lights that make me feel like I'm taking part in a NASA stress test for astronaut candidates.' Elgan calls on manufacturers to respect his 'Gadget Bill of Lights' to restrict the use of nag lights and allow users to turn them off. He also says the industry should pay more attention to industrial design when creating new products."

Radon360 writes "Kodak has decided to attempt to buck the trend set by HP by offering low cost printers and reasonably priced ink cartridges. Three of their new printers start at $149, with ink cartridges costing $9.99 for a black cartridge and $14.99 for a five color cartridge. To counter, HP has announced a release of lower-priced cartridges, though with less ink and they are still more expensive than Kodak's. It will be a matter of time to see whether Kodak can upset the practice of ink cartridge extortion."

An anonymous reader writes "Are original inkjet cartridges really worth the high cost? Do third party refill inks do as good a job? This article looks at printers from Epson, HP, Canon and Lexmark, with a combination of original inks and the top selling third-party options, using a whole host of different papers. A panel of printer users judged the output in a blind test — the printer manufacturers may not be happy with the results!"

An anonymous reader writes "HP has launched a new line of business printers but there's a big catch — you won't be able to buy one. For the first time in history, the company will make customers purchase printing services, rather than the product itself. At its biggest printer launch since the LaserJet in 1984, HP's new business-class Edgeline printers will only be available through a managed services contract. Pricing will be per page, depending on the quality of the printout. Edgeline technology is said to be so ink-efficient that if HP were to sell these printers, they would never match the money they make from consumables (cartridges etc) now."

An anonymous reader writes "What will it mean when 3D fabricators become cheap and common? A NY Times article explores the ease of copying objects by scanning them with NextEngine scanner and sending them to 3d 'print shops'. The experiments were done with Legos because most of the things around his office were protected by copyright. What will happen to the economy for engineering when we can just download a pirated description of a machine and 'print' it out? 'The world is just beginning to grapple with the implications of this relatively low-cost duplicating method, often called rapid prototyping. Hearing aid companies, for instance, are producing some custom-fitted ear pieces from scanned molds of patients. Custom car companies produce new parts for classic cars or modified parts for hot rods. Consumer product makers create fully functional designs before committing themselves to big production runs.'"

Michael Flynn writes "The DV Rebel's Guide is broken down into chapters that follow the basic timeline of a film's production. The first chapter covering the overall philosophy of the authors approach and the rest focused on the making of your film: Pre-production, Production and Post production. A great deal of the book is focused, to very good effect, on post production." Read on for the rest of Michael's review

sarahbau writes "Silverbrook's new Memjet technology can print 60 full-color pages per minute. Instead of having a print head that moves side to side like current inkjets, the print head spans the full width of the page, containing 70,400 nozzles in the A4 version. They also have a large-format printer (51") that prints 6" to 1 foot per second. Products are expected to start shipping in late 2007: first a photo/label printer, then a home/office printer for less than $300 in 2008." The video is amazing. If it's for real, the technology would be disruptive at half the speed and twice the price.

nomoreself writes "PhysicsWeb reports that a team of scientists in Jerusalem has come up with a method for creating self-assembling 3-dimensional models from a single sheet of paper. The 'chemical origami' is created by etching a pattern of monomer onto the paper and then heating it. The chemical's reaction to the heat causes bends of varying degree in the paper, molding the sheet into the patterned model. A professor in the US with no apparent ties to the study says in the article that the technique could be used to create self-assembling prototypes, or even a printer that prints 3D objects."

Iddo Genuth writes "Xerox is developing a new printing technology which does not require ink of any kind. The new technology includes reusable paper which can be printed and erased dozens of times and has the potential to revolutionize printing. New details on this upcoming technology, which was first reported in September 2006, are now revealed."

Henry V .009 writes "Scientists in New Jersey are claiming that children with autism are unable to metabolize key fatty acids that fight brain-damaging inflammations. They have already developed urine/blood tests to identify at-risk children. A preventive cure to autism may be as simple as a 'therapeutic cocktail' of fatty acids. Human trials could start later this year."

John Suda writes "It's been over five years in the making and its nearly perfect. No, Im not referring to Microsoft's vast new operating system named Windows Vista, but to the reference book Windows Vista: the Missing Manual, by author David Pogue. The book is the latest, and perhaps best, in the Missing Manual series published by Pogue Press / O'Reilly Media, Inc. The Missing Manual series is the benchmark of quality for computer manuals. Unless youre a system administrator, programmer, or uber-geek, this is probably the only reference source you'll need to learn Microsofts Vista." Read below for the rest of John's review.

An anonymous reader writes "An ex-HP exec claims he was instructed by the company's management to spy on Dell's printer business plans. Karl Kamb, previously HP's vice president of business development and strategy, was named as a defendant in a federal lawsuit filed by HP in 2005, after he allegedly began his own company before leaving HP. Kamb, who has denied any wrongdoing, filed a countersuit in US District Court for the Eastern District of Texas claiming he was fired because of shading dealings involved in the corporate espionage. From the article: 'As a member of HP's imaging and printing group's "competitive intelligence team", Kamb said he was in a position to know that HP senior executives signed off on a plan to pay [Former Dell Japan President Katsumi] Iizuka to obtain details of what Dell was up to. Iizuka turned over the information to Kamb and he passed it along to HP, Kamb claimed.'"

gbjbaanb writes to point out an article in the Sunday Times describing two separate programs where robots are being developed to build houses. The Los Angeles project is farther along than the one in the UK, but the article provides more details on the techniques employed in the latter. Liquid concrete and gypsum will be sprayed from nozzles in a manner analogous to an inkjet printer. From the article: "The first prototype — a watertight shell of a two-story house built in 24 hours without a single builder on site — will be erected in California before April. The robots are rigged to a metal frame, enabling them to shuttle in three dimensions and assemble the structure of the house layer by layer. The sole foreman on site operates a computer programmed with the designer's plans... Inspired by the inkjet printer, the technology goes far beyond the techniques already used for prefabricated homes. 'This will remove all the limitations of traditional building,' said [an architect involved with the UK project]. 'Anything you can dream you can build.'"

Migraineman writes "I stumbled upon a clever hack by Sprite. He reverse-engineered the pin functions on an HP inkjet cartridge and built a simple driver board that converts the cartridge into a hand-held inkjet printer. The driver board is programmed with a fixed message. Moving the 'print head' is your responsibility. Printing messages on a whiteboard was the original inspiration, but printing messages on the foam head of a Guinness is just inspired."

holy_calamity writes "Two Cornell researchers have designed an open source 3D printer that costs just $2,400. The self-assembly kit is part of what they call the Fab@Home project — they hope it will spark development of rapid prototyping for the consumer market in the same way the Altair 8800 did for personal computing in seventies." Here is a video showing a completed machine constructing a silicone bulb (16-MB WMV).
Update: 01/10 04:02 GMT by KD : The developers of this kit are at Cornell, not Carnegie Mellon University as the original post erroneously stated.

Carl Bialik from WSJ writes "A tech columnist looked around his home and wondered, 'All these TVs and cable boxes and computers and computer gear and chargers for various adapters have to be sucking up a lot of power, right?' So WSJ.com's Jason Fry bought a power meter to find the biggest power hogs in his home. They weren't his newfangled gadgets: 'The heavily used agglomeration of PC / two monitors / printer / hard drive / speakers in my downstairs study costs a bit more than $10 a month. The PC in our bedroom costs about $6 a month. The upstairs laptop? Less than $1 — a bit more than other always-on gadgets such as the router, cable modem, wireless repeater and Airport Express. So what were our apartment's power hogs? The lights and the dryer. I estimate our lights cost us around $30 a month, nearly a third of that from a chandelier with eight bulbs. Then there's the dryer. I don't know exactly how many watts it uses, but estimate it's costing us at least $25 a month.'"
