Inkjet Cartridges To Save Your Kidneys
Posted by John Mahoney at 10:40 AM on October 16, 2008
Sometimes it's hard to remember that inkjet printers are good for anything other than ripping you off, but news today from HP's own intellectual property czar may change that: the technology that regulates the precise mixture of pigments down to the last picoliter will soon make home kidney dialysis machines more accurate by regulating mixtures of dialysis fluid with similar accuracy.

Over at NextFest, we came across an entire tree's worth of Xerox's cartridge-less solid ink, a technology we'd heard about but never seen in person. They feel more like a hard, textured plastic than a waxy crayon (which is its most touted analogy), and the ink doesn't rub off in your hand at all. And yes, Xerox, we'll be happy to buy your product that reduces ink waste by 90% if you'd kindly release it to the market.
This new photo-printer from Casio is one mixed-up gizmo: As well as standard photo-printing functions, it's got a 7-inch touchscreen and a full keyboard. So is it a mini computer with printer aspirations, or a printer with computing aspirations? Hard to say, but it's supposedly able to edit the photos you pop in from a memory card or mobile phone, and produce custom greetings cards, calendars and the like. And it comes with hundreds of built-in stamps and illustrations. You'd better be seriously into DIY greetings though: the PCP-1200 costs a whacking US$500 in Japan. [
Trusted Reviews has a big investigation on inkjet printers and inkjet ink, and their year-long study comparing fading between more expensive manufacturer brand vs. the cheaper crappy brand shows that you get what you pay for. Over three months, the differences between the two were negligible, with pages only fading slightly (but noticeably) in quality.
I can't say that I have ever been impressed by a printer, but the device they are cooking up at Kyocera could be a first. Their new KJ4 series printhead can churn out up to 200 metres per minute at 600 x 480 dpi, or 150 meters per minute at 600×600 dpi—which equates to about 1000 sheets of A4. After consulting a calculator, I determined that is nearly 17 pages a second.

Designer Hung Chih Wang thinks the inkjet printer market has room for an ultra-mobile concept: his "Trak" design is a mini printer that snaps onto the lid of your laptop. Handy for hardcopies on-the-go, it's small enough to be USB powered and even has a detachable print head for easy travel storage. There's no mention of how you keep the ink from spilling in your bag, but that should please those dollar-craving ink manufacturers, eh? [
Scientists at the University of Tokyo have developed a new 1mm thick plastic sheet inkjet-printed with various nanoparticles and insulating and semiconducting polymers that enables electronic devices placed on it to communicate with one another. A technology like this would have advantages over other means of short-range wireless communication (like Bluetooth) because it is inherently more secure and power efficient.
HP has figured out a way to make their inkjet technology a bit more versatile: by getting it to inject drugs into humans. Yep, HP is looking to replace hypodermic needles with their inkjet technology in a method reminiscent of nicotine patches. HP is licensing a patch with up to 90,000 microneedles per square inch which could then inject drugs into a patient either over time or when certain conditions (i.e. blood pressure) are met. It would allow injections to be much more precise, which is good. Also, you wouldn't need to get injected with a big scary needle anymore, which would also be good. [
Two hundred bones will get you a lot of printer these days. Epson's Stylus Photo RX680 printer/scanner/copier is a Gutenberg wet dream with text and copy speeds up to 40 ppm, two separate paper trays that can hold a total of 270 sheets of paper, draft photo printing in 11 seconds and an auto-duplexer for hassle-free double-sided action.
