    Hello:

    It is not often people write emails or letters of praise but consider this one of the rare ones!
    I must say, ordering your product was about the easiest imaginable. Coupled with the fact that it arrived here basically “next day” I am thoroughly happy. To tell you the truth, I was expecting to have to go pay full retail for one black cartridge thinking that your’s would take at least a week to arrive but I was wrong, the order arrived before I could even go out to get one!
    Congrats people, I WILL tell all my friends and neighbours about you!

HP Unveils Innovative Inkjet Supplies Strategy

Friday, April 27, 2007

More Inkjet Cartridge Options
(Media-Newswire.com) – HP is changing the way it delivers inkjet cartridges to customers to offer them more choice, greater value and a simplified shopping experience, both in-store and online.Beginning this year, most new HP consumer printers worldwide will be introduced with multiple inkjet cartridge offerings that are designed to provide customers with options that better meet their printing needs.

Red, Blue, Green Color Coding
In addition, the new cartridge options will deliver value by offering low purchase prices to customers who print a little, and lower cost-per-page to customers who print a lot.In conjunction with these new cartridge offerings, HP is rolling out a new color-coded packaging system across its entire inkjet cartridge portfolio. Three color-coded categories � standard ( blue ), value ( green ) and specialty ( red ) � will allow customers to walk into a retail store or log on to hp.com and quickly and easily scan their options to find the right cartridge that offers the best value for their printing needs. All three categories deliver the superior reliability and print quality customers expect from HP.

Whats Best for you
For the majority of new HP printers, the inkjet cartridge options will be: �Standard� cartridges ( blue packaging ), which have a lower purchase price, are designed for customers who print a small number of pages on a weekly or monthly basis. Beginning in 2007, HP will introduce an increasing number of standard cartridge offerings in the $14.99 price range for those customers who still want access to high-quality printing, but don�t want to pay a lot at the point of purchase. �Value� cartridges ( green packaging ), which are designed for customers with higher volume printing needs, offer a lower cost per page compared to standard cartridges. This line will include new high-yield �XL� cartridges that provide customers approximately 30-45 percent savings on a cost-per-page basis, print up to three times more pages, and require fewer cartridge replacements compared to standard cartridges. Customers can easily identify the new value option by looking for the green packaging and the letters �XL� next to their cartridge number. �Specialty� cartridges ( red packaging ), which offer additional performance features compared to HP�s standard ink formulations, are ideal for customers with special applications and printing jobs, such as professional-quality photographs. �

Multiple Options
For more than 25 years, many HP printers offered customers only one cartridge choice. Now, the majority of our printers will offer customers multiple options,� said Pradeep Jotwani, senior vice president, Supplies, Imaging and Printing Group, HP. �Delivering customer choice and value is critical for driving continued growth, and the unprecedented level of innovation HP is applying toward the customer experience is as important as the innovation behind the technology that goes into our high-performance ink and paper products.�Improved shopping experience To improve the customer purchasing experience, HP has extended its color-coded system to point-of-sale materials, such as updated ink selection guides. The changes will attract shoppers� attention in retail aisles and direct them to the appropriate supplies � helping to educate people about their choices and increasing overall customer satisfaction. Similar point-of-sale tools and the new look and feel will be employed online at www.hpshopping.com to quickly guide customers to the right supplies for their printer and printing requirements. Downloadable photos of HP�s new inkjet cartridge offerings, as well as a video showcasing HP�s retail and online makeover, are available online at www.hp.com/go/supplieschoice. About HPHP focuses on simplifying technology experiences for all of its customers � from individual consumers to the largest businesses. With a portfolio that spans printing, personal computing, software, services and IT infrastructure, HP is among the world�s largest IT companies, with revenue totaling $94.1 billion for the four fiscal quarters ended Jan. 31, 2007.

Printing goes Wireless at Lexmark

Friday, April 20, 2007

Lexmark makes wireless printing AIOs
 
Lexmark is launching a new range of printers in the UK, with a new selection of wireless printers .

‘The company previewed the products at its Global Press Event in Kentucky, with Jeff Willard, vice president and general manager at Lexmark, and Jeff Meredith, director of product marketing, claiming the company’s new range will help consumers increase productivity.

Less than $100

The Lexmark execs said there’s been a surge in the number of homes with an all in one in recent years, largely due to increased affordability. Lexmark sees itself as central in driving this growth, having introduced the sub-$100 colour inkjet in the US in 1997 and sub-$200 all-in-one in 2001.

Wireless represents the Driving Technology

But wireless networking is expected to be one of the top drivers of productivity over the next five years, according to results of Lexmark’s 2007 Wireless and Printing survey. The company said printing has evolved, but wireless printers have previously been too expensive and complicated. In 2007, however, Lexmark predicts this will change.

“Wireless is the next big thing in inkjet printing and we will be providing easy-to-use and affordable wireless printers,” said Willard. “Lexmark will drive the explosive growth in the printing category and give customers access to something they previously couldn’t afford.”

Inkjet Printed Circuit Boards

Printed Circuit Boards

Well we have all heard of those electronic wonders called PCBs “Printed Circuit Boards”. Its the place where all electronic components are placed to make a working electronic device.

Inkjet PCBs

What are inkjet PCBs. Well as the name implies, the ink solution is replaced with a solution of metal salts and water” and print out an actual electronic PCB.

Leeds Leeds the way

Leeds University’s Seyed Bidoki was recently able to print out an actual electronic circuit. The mysterious “silver salt solution” and vitamin C mixture could be used to “pave the way for safer and cheaper electronics manufacturing,”

Environmentally safe solution

This cheap and easy alternative should certainly be a hit with the environmentally conscience crowd. This method utilizes a water-soluble base, which differs from the less green solvents used in polymer ink / graphite paste from before. Individuals working with the project admit that ousting the current regime will be difficult. The crew is non the less, pressing forward with this toxin-free approach, and hopes to elicit the help of “industrial jet printers” before long to speed things up.

Making Bones from an Inkjet Printer

Artificial Bones

Scientists are creating artificial bones using a modified version of an inkjet printer.
The technology creates perfect replicas of bones that have been damaged and these can then be inserted in the body to help it to heal.

A modified ink-jet printer can be used to directly print layer upon layer of artificial bone for quick-fix grafts used in reconstructive surgery.

The process will revolutionise bone graft surgery, which currently relies on either bits of bone taken from other parts of the body or ceramic-like substitutes.

Repairing Bones

Bone takes a long time to grow and repair, so treating serious damage or carrying out reconstructive procedures can be a slow and painstaking process.

In issue 6 of Advanced Materials, Jake Barralet of the Faculty of Dentistry, at McGill University, (Montréal, Québec) and Uwe Gbureck, Department for Functional Materials in Medicine and Dentistry, University of Würzburg, (Bavaria) and their team describe a method for “printing” artificial bone from the same chemical components as living bone and including biomolecules that trigger blood vessel growth to bring the bone to life after it is implanted in the body.

Cement Paper and Acid Ink

Professor Jake Barralet of McGill University in Montreal, Canada, explained: “The “paper” in our printer is a thin bed of cement-like powder. The inkjets spray the cement with an acid which reacts with it and goes hard.

The McGill – Würzburg team has demonstrated how an artificial bone can be constructed using the minerals brushite and hydroxyapatite instead of conventional “ink” in their printer. By printing one layer on top of another they can build up a highly porous 3D bioceramic material resembling bone at room temperature.

The team also adds natural chemicals to stimulate blood vessel growth – vascular endothelial growth factor (VEGF) or copper sulphate. This allows them to incorporate into their model bone implants the necessary materials for stimulating blood vessel growth and allowing the artificial bone grafts to “grow” into the site being repaired.

It takes only ten minutes for the printer, which is the size of about three filing cabinets, to print a typical bone graft.

Bone Graft

The printed graft acts as a bridge to allow the body to replace the damaged section with new bone. Crucially, the substance created by the printing process contains the same building blocks as real human bone, allowing the graft to eventually dissolve harmlessly into the body.

The sections made by the printer are so precise that spaces can be left to encourage the regrowth of tissue and blood vessels through the graft, mirroring the make-up of normal bone.

Professor Barralet said: “The holes in the bone graft will affect how new bone grows into the graft. ”

Custom Design Fit

“You can design it so you encourage it in a particular direction, to get different tissue repair. It is mainly useful in areas where you need a very good sort of fit, like cosmetic surgery or reconstructive surgery, or in the spine where you don’t want to be playing around to get something to fit.

“We’re a long way from seeing this used in a hospital setting, but it’s an important first step.”

Embedded Head Printers move to HP

Inkjet versus Laser

In a continuing battle between Inkjet and Laser(s) HP has introduced a new line (Edgeline) of office printers that appear to be able to take on the Laser printer market. HP new series uses an inkjet print head (fixed) that spans the entire width of the printer(s) paper page. This means there is no longer a moving printer head, and only the paper moves.

Breaking with Tradition

HP has traditionally sold inkjet printers using removeable head technology, where the user would discard the head assembly after each cartridge was used. Now, this new technology uses an embedded print head (Non User replaceable) and only ink needs to be purchased to keep this printer going.

How fast is fast ?

HP CM8060 Color MFP

How about 71 pages per minute ? Yes that’s right.. 71

Very quickly inkjet is taking over as the top dog in print speeds versus traditional laser printers, and no more messy toner drums to change. The only advantage that lasers had over inkjets in the past was that their toner adhered to the paper and was not water soluble. With the recent introduction of water resistant inkjet(s) their advantages will soon be overtaken by this new breed of inkjet printer.

End of the BubbleJet Printer improvements in sight

End of the BubbleJet Printer improvements in sight

Traces of nanobubbles determine nanoboiling
 
BubbleJet printers use heating elements to effectively Bubble off ink within a Print Head causing the resultant bubble of ink to be imprinted on the papers surface. Using a microscope and some extreme “snapshot” photography with shutter speeds only a few nanoseconds long, researchers from the National Institute of Standards and Technology (NIST) and Cornell University have uncovered the traces of ephemeral “nanobubbles” formed in boiling water on a microheater. Their observations* suggest an added complexity to the everyday phenomenon of boiling, and may affect technologies as diverse as inkjet printers.

An Undeveloped Science
 
You might think that the science of boiling had been worked out some time ago, but it still has some mysteries, particularly at the nanometer scale. As water and other fluids change from their liquid state to a vapor, bubbles of the vapor form. The bubbles usually form at “nucleation sites,” which can be small surface irregularities on the container or tiny suspended particles in the fluid. The exact onset of boiling depends on the presence and nature of these sites.

How They did it
 
To observe the process, the NIST/Cornell team used a unique ultrafast laser strobe microscopy technique with an effective shutter speed of eight nanoseconds to photograph bubbles growing on a microheater surface about 15 micrometers wide. At this scale, a voltage pulse of only five microseconds superheats the water to nearly 300 °C, creating a microbubble tens of microns in diameter. When the pulse ends, the microbubble collapses as the water cools. What the team found was that if a second voltage pulse follows closely enough, the second microbubble forms earlier during the pulse and at a lower temperature apparently, as conjectured by the team, because nanobubbles formed by the collapse of the first bubble become new nucleation sites for the growth of later bubbles. The nanobubbles themselves are too small to observe, but by changing the timing between voltage pulses and observing how long it takes the second microbubble to form, the researchers were able to estimate the lifetime of the nanobubbles—roughly 100 microseconds.

Nanobubbles disrupt higher speed inkjet printer Bubble formation
 
These experiments are believed to be the first evidence that nanoscale bubbles can form on hydrophilic surfaces (previous evidence of nanobubbles was found only for hydrophobic surfaces like oilcloth) and the method for measuring nanobubble lifetimes may improve models for optimal heat transfer design in nanostructures. The work has immediate implications for inkjet printing, in which a metal film is heated with a voltage pulse to create a bubble that is used to eject a droplet of ink through a nozzle. If inkjet printing is pushed to higher speeds (repetition rates above about 10 kilohertz), the work suggests, nanobubbles on the heater surface between pulses will make it difficult or impossible to control bubble formation properly.

Epson releases new Ultra Thin Piezo print head

Epson releases new Ultra Thin Piezo print head

Thin-film piezo offers Highest Distortion

According to Seiko Epson Corporation , they have developed a thin-film piezo element that boasts the world’s highest degree of distortion. Epson announced volume production of next-generation Micro Piezo print heads that feature these elements as actuators will be launched in April 2007.

Current Micro Piezo Print Head Overview

The Micro Piezo print head is an inkjet print head which utilizes Epson’s original Micro Piezo technology. This technology uses electrical signals to change the shape of piezo elements and then fires ink droplets according to the physical force generated by the change in shape of these elements. Epson’s Stylus Photo and Stylus Pro inkjet printers, which utilize Micro Piezo print head technology, are photo-quality printers that have consistently played leading roles in the Japanese inkjet printer market and earned high approval and trust from customers.

Newest Developments

Epson is currently focusing its development efforts on creating a next-generation Micro Piezo print head to support expansion of the inkjet field beyond consumer printers and to strengthen its applications for business and industry. Through these efforts, Epson has achieved the following:

a) Created a piezo element with the world’s highest degree of distortion through film thickness reduction and materials development.

b)Raised density levels by developing and utilizing innovative thin-film processing techniques.

c) Designed a high-density ink reservoir through independent MEMS technology development.

Benefits
 
As a result, Epson has managed to develop a nozzle with a density of 360 dpi—the world’s highest for an inkjet print head using piezoelectric technology—while at the same time maintaining the advantages of conventional Micro Piezo print heads.

Epson has also managed to establish a completely independent manufacturing process by producing the piezoelectric materials in-house.

The installation of these next-generation Micro Piezo print heads in printers and other devices will make it possible to design speedier and more compact inkjet equipment than ever before.

Current Technology

Special characteristics of Epson’s original Micro Piezo print head

This print head fulfills all the requirements for an inkjet print head—superior ink ejection performance, compatibility with a wide variety of inks, and durability. The print head also makes it possible to control not only water-based pigment ink with superior water and light resistance, but also a wide variety of ink types in miniscule quantities, and fire them with high precision.

1. Ink ejection performance* Meniscus control, which limits vibration on the surface of the liquid in the nozzle, makes it possible to achieve improved gradation and faster print speeds in addition to the following advantages:

a)Perfectly spherical dots

b) High precision impact point control

c) Higher drive frequencies

d)Variable-sized ink droplets (MSDT: multi-sized dot technology)

2. Ink compatibility* Epson’s original pigment ink achieves high levels of color reproduction and durability.* Industrial applications such as solvent ink, color filters, and UV ink are currently under development.

3. Durability* Because it utilizes a permanent print head, the technology is applicable to a wide range of uses ranging from consumer printers to industrial manufacturing equipment.Features of the next-generation Micro Piezo print headBy independently developing a thin-film piezo element which has the world’s highest degree of distortion and using it as an actuator, Epson has succeeded in taking full advantage of the features of conventional Micro Piezo print heads while at the same time doubling nozzle density. A conventional Micro Piezo print head’s nozzle density is 180 dpi (maximum) whereas a next-generation Micro Piezo print head’s is 360 dpi.
