History of Inkjet Printers

On the TCD official blog I posted the first part of a big article on history of inkjet printers:

In the early 1980s, introduction of the laser printer met that need. By eliminating the need for physical impact against a ribbon, laser printers achieved much higher speeds and were able to work in almost silence. As personal computers grew popular during the 1980s, laser printers became the only acceptable choice for “letter-quality” printing, regardless the cost of several thousand dollars.

However, the laser printer’s reign was eventually overtaken by a technology developed at the Hewlett-Packard. HP, along with Epson and Canon, can claim a substantial share of credit for the development of the modern inkjet, and we will consider the history of inkjets from the HP’s point of view.

Funny thing is, HP’s invention was not originally intended for personal computers, since when the project began in the late 1970s, there were no such things. Instead, HP was looking for a new printing mechanism for portable, battery-powered calculators, its most profitable consumer product.
As a responsible author, I did a research on the topic, from which a learned a lot of interesting facts about how inkjet technology as we know it came to existence.

Another 1,000 Pages In 1 Minute

Recently, we have seen two similar technologies revolutionizing the speed of inkjet printing — HP’s Steamline and Silverbrook Memjet. The innovation factor was in creating a fixed printhead spanning the whole width of the page.

Two Israeli researchers The College of Judea and Samaria — Moshe and Nissim Einat — have developed a revolutionary printing technique called Jetrix. This technique take printing speeds even higher – up to 1,000 pages per minute — since it enables simultaneous high-speed printing of an entire page of text.

Jetrix is a mixture of Inkjet Technology and Liquid Crystal Technology. Inspired by LCDs that could instantly create an image with a screen-sized array of diodes, Moshe Einat started to wonder if the same idea could be applied to printing the whole page. Inspiration led to creation of a page-size matrix of printheads with multiple ink chambers.

These chambers are the key to the new technology. Each chamber is a tiny tank of ink connected to just a few nozzles and supplying only those nozzles. The chambers are not connected with one another, so the matrix of printheads can be created as large as the paper, without limit.

The built prototype can only print black and white, but Einat is sure the idea can be realized in full color too.

Yes, there are printer that can print as fast as 1,000 ppm, but they are room-sized. This new printing technology allows making printer more compact. We shall wait for the first full-working printer to appear.

Xerox Invisible Fluorescent Printing

Group of Xerox scientists devised a new method for printing hidden fluorescent text using standard printers. The fluorescent text is only visible in ultraviolet light, at the same time it does not require fluorescent toner to print it.

This new method is side product of Xerox’s larger studies to put more security into digitally printed documents by making any element on the page-—such as lines, text, and images-—unique to the recipient. The scientists were playing with differential gloss in a toner to print a hologram-like image, when one of them, Reiner Eschbach, started to wonder if there was any chance to make fluorescent marks using regular toner.

Eschbach's group tried different toner combinations to achieve paper's fluorescence shining when exposed to ultraviolet light. They come to this after they realized most paper already contains fluorescent brightening agents added by manufacturers to make the paper look whiter.

According to the company, the new method of fluorescent printing allows adding more security to commonly printed materials such as checks, tickets, coupons, and other high-value documents.

Interview with HP Vice President Vyomesh Joshi

PC Magazine published an interesting interview titled ‘We Could Ink Jet Anything’ with Vyomesh Joshi titled, executive vice president of HP's Imaging and Printing Group. Simply put, he is the one in charge of HP printer business.

He opens the conversation with a brief overview of how printer business in HP has changed.

“We are focusing on pages. From a page point of view, 48 trillion are printed a year. Now we measure our market share in pages, and we are less than 2 percent. When you start thinking about pages, we have a tremendous opportunity.”
Then he moves to the issue of printing less in the modern online world:
“In 1984 we were promised the paperless office. And in 2006 we are using ten times more paper.”
Also, Vyomesh Joshi tells about new imaging devices coming up, gives his prospect of view on the new implementations of inkjet technology, such as DNA sequencing, 3-D printing and competitors achievements.

As a person who is into printing, I had a great time reading the interview.

Print Greener, Print Cost-Effective, Print Smart

In modern world of electronic communications people still have to do a lot with paper. Course projects, year reports, club flyers, advertisement brochures – all that required paper. In a known fact that paper is made of processed trees. Thus, the more pages is printed, the more trees are cut.

In effort to make printing more environment friendly, GreenPrint Technologies developed a software that would reduce amount paper waste in office printing. Recently launched in United Kingdom, GreenPrint Enterprise software highlights and removes unwanted pages before they are printed, creates PDF files as alternative for printing. Also, it gives a print overview, so users can easily decide what stays and what goes. Besides, the software has other options for ink and toner saving.



GreenPrint Enterprise incorporates a feature that reports how many trees were saved during the use of application. The company estimates that an organization employing 20,000 people could save GBP1.3 million annually, which equals 35.2 million pages or 3,911 trees.



GreenPrint Enterprise software is optionally accompanied with GreenPrint EverGreen Font. This font was specially “designed to allow more words to fit on each printed page without compromising readability. Compared with common fonts such as Arial, Times New Roman and Helvetica, EverGreen reduces paper use by 15-20%.”

Three Dimensions for Your Home

If you ever dreamt of a device that would produce real objects, then your dream is coming true. Three-dimension printers have always been something large, expensive and available only to chosen ones. Until now.

Desktop Factory made 3-D printer smaller, cheaper and more affordable. The company will start selling its first printer for $4,995 this year, and price is expected to fall to $1,000 in next four years. So in the nearest future 3-D printer would be available to home users.

How does the printer actually work, you may ask. The plastic powder, an analogue of toner in regular printers, is dropped on and sticks to a heated roller, where it is fused with a light beam to make an image. Then image is rolled onto metal plate to form a layer. The plate moves down as more layers are stacked to make an object. When the object is created, the plate moves up to squeeze the layers under heat and fuse them. (Pictures taken from www.nytimes.com)

The printing method is yet to be improved, because the model makes objects with rather jagged edges and rather sandy finish that many do not find attractive, NY Times story tells. But there is demand that does not require high quality and cannot afford large printers.

The picture above shows what kind of object the new 3-D printer can create. They say more 3-D objects blueprints will be available later on the Internet for people to download and create.

"Gelly" Printers by Ricoh

Ricoh UK introduced a new range of desktop printers using gel-based color-system. The new Ricoh Aficio GX3000, GX3050N and GX5050N have a high speed of printing, up to 30 pages per minute in monochrome and color. The speed could be compared to the speed of laser printers, but the price is more like that of inkjets.



Ricoh proprietary GelSprinter Technology uses pigment-based liquid gel that sits on the media surface, but not diffuses into it as inks do. The company says the printouts are fast to dry and waterproof, which makes a double-side printing possible. Besides, the printers feature Electrostatic Belt Feeding System that is supposed to hold paper firmly in place and prevent paper jams.

New printers use special gel cartridges of standard (cyan, magenta, yellow and black) color. One color cartridge yields 1,150 pages, while a black cartridge is enough to print 1,450 papers, as stated on Ricoh site. Priced £28.45 and £22.45 (approximately $57 and $45) for color and black cartridge, respectfully, these cartridges are somewhat in the middle between ink and laser printer cartridges, when it comes to yield/cost effectiveness.

We shall see if this gel technology proves to be viable.

How Would You Like Your Toast? – Printed!

Many areas of human life have enjoyed the printing technologies – medicine, electronics and so on. However, as time goes by, printing finds new, absolutely unexpected areas of application. This time it all started with fun, when guys from Evil Mad Scientist Laboratories used a hot-air gun to make images on a slice of toast.

Not satisfied with results of hand drawing, they decided to mount the hot-air gun to the carriage of a 3D printer they built for their previous project. Since toast printing does not require third dimension, Z-axis of the printer was disabled. With hot-air gun used as a printhead, they achieved a resolution of 10 dots per inch (2.5 mm pixel size).

Also, the printer was could make photo images on a toast, which required some additional adjusting (air flow rate, temperature, etc.) of printer hardware, actually the hot-air gun.

Below is a video of how toast is printed using digital toast imaging technology.

From A Comment To A Post

This post was initially meant to be a comment to this post I occasionally came across. The guy’s a designer and an inkjet owner facing the problem of expensive cartridges for his Epson. I found his blog occasionally and was already writing a reply to the post, when realized it’s more like a separate story, not just a comment.

I'm not a designer, though now I do print photos and color graphics sometimes. I also faced the need for color calibration to get better results when I bought my color inkjet printer. It was Canon Pixma i1500. Purchased mainly for printing text, it proved produce photos of decent quality. Being a person who delves into details, I wanted to get best out of my printer. So I tried to find the best way to produce fine quality photos at reasonable cost. ‘Reasonable cost’ didn’t only mean money, it was also amount of efforts I have to put in to get that best results.

I tried different color profiles and different photo papers. Eventually, super-duper photo quality (if you ever get this from a $60 inkjet - that's how much it cost year and a half ago) I was aiming for was compromised for simplicity – I settled for automatic presets. It seemed sensible to me that Canon digital camera and Canon printer should work well together without me jumping around and doing Woodoo magic, and it worked out. I used and still use Lomond Super Glossy Paper, by the way.

Before my Canon inkjet, I used to have an Epson one. The reason I switched to Canon was cheaper OEM cartridges, since firstly I didn’t plan to print a lot, paying extra $5 for brand name was not a problem. However, over time printing volumes increased, partly with the discovery of decent photo printing ability. And when my family began using the printer, too, the extra $5 started making difference to me.

I went to the nearest printer cartridge outlet. Along with original supplies, they sell compatible and refillable cartridges. The difference between the two, they told me, is that refillable cartridges can be refilled with ink many times. Well, actually other cartridges can be refilled too, but they are not very much designed for that, as far as I could get.

I bought black and color cartridges by Sky Horse, and they cost me only $4.5 and $5.5, respectively. At home, I only had color cartridge depleted, so I changed it and reset ink level counter. Then I printed a test color page (little graphics, mainly text), which was OK. However, to be 100% sure it’s OK, I printed a 4x6-inch photo of food and flowers which means lots of small details, variety of colors.

I have absolutely no illusions about this being a professional super-color-match-whatever test. But I was completely fine with what I got. So, I decided to stick with refillables, they provide the quality level I require and they don’t cost much.

Now that I found a cheap source of ink, later I plan on upgrading my printer, probably to an inkjet multifunctional. More and more often I need copying option and my printing volumes are not that large to buy a laser one.

Inkjet Printer Creates Body Organs

A news that coincides with one of my previous posts, where I reported use of inkjet printers for creating artificial bones. Scientists at Wake Forest Institute of Regenerative Medicine are using inkjet printers to create organs and tissues, that’s something that could change the very way of studying tissue engineering.

(picture from www.newscientist.com)

Regular ink cartridges available almost everywhere are emptied, cleaned and filled with the cells needed to create the organ. Then, an inkjet printer prints these cells into a substance resembling human tissues. Printed layer by layer, cells form the required shape of muscle or organ.

Adopting inkjet printers for the need of tissue engineering resulted in more precise, accurate, fast and, most importantly, controlled creation of biomaterials.

It seems to me that inkjet technology for today’s science is like an invention of the wheel for our ancestors – it’s spread far over the area it was designed for.

Web Friendly Printer by HP

If you ever tried printing a random web page, you probably know that what you get is far from original. There are stripes of white space, images chopped in two, text cut from one side, and so on. That’s annoying. On the other hand, with the development of Internet era people tend to print less, partially because of such web-hostile printer behavior.

Hewlett Packard is reported to address this problem. They have numbers showing that a good half of the materials printed at home is from Internet, while computer software generates only 20 percent of printing. Internet is infested with blogs and pictures galleries, which can spur the demand for printing, provide printers are web friendly.

In effort to stimulate home printing, HP resorted to help of a side company, Tabblo, a developer of Web-based software. The software creates templates that reorganize the photos and text blocks on a Web page to fit standard sizes of paper. HP wants to make this software a general standard, like Flash or Java. With such printing engine of the Web, HP will help all printer companies, but being the industry leader, it will surely benefit the most.

How Toner Is Used in Printers

Surfing the net today, I came cross a thread where they discussed whether a laser printer uses equal amount of toner regardless of each print density, or not. That probably happens in laser printer cartridges with magnetized toner pickup rod, but not likely. The truth is the printer uses toner according to actual print density. And the amount of pages that can be printed is calculated based on an average of 15% print density of an 8 x 11 inch paper. Also, it seems like laser printers and photocopiers using toner all have recovery mechanisms which transfers unused toner back into the reservoir.

60 Pages Per Minute Inkjet Printer

An Australian company Silverbrook Research announced a technology called Memjet it’s been working on for a decade. The technology required to over 1400 patents.

The developer asserts the innovation will enable a jet print speed unheard of before – 60 pages per minute in color.

In printers supporting Memjet Technology, the printhead that span the width of an A4 page. First such printers are going to be quite affordable – around $200, and the ink price is good too – less then $20 for 50 ml.

Technical specifications for Memjet Technology are expected the soonest (currently, they charge around $3000 for a detailed report on implemented technologies). You can view a video demonstrating the speed of a prototype built on the new technology.

Truth to be told, I see it as as logical continuation for the previous post. This is a great idea to make a printhead as wide as a sheet of paper to print on. I just wonder why it took 10 years and millions of dollars for the idea to emerge.

Best of Laser and Inkjet Printing by HP

Hewlett Packard has developed a unique Edgeline and Scalable Printing Technologies for high-speed quality high-volume printing at low running costs.

The development has taken $1.4 billion and over 4 years of work. The goal of the research was to create single printing mechanism using advantages of both laser and jet HP technologies. As a result, the developed Edgeline technology has considerably increased the speed of printing and it’s outstanding quality.

The HP engineers have managed to combine best features of inkjet and laser printing: high speed, quality of text and graphics, low print cost per page and the lowest general running costs.

Edgeline Technology is one of a kind – printheads are positioned sheet-wide, so the only thing that moves during printing is paper. The speed increase has been made due to linear positioning of big fixed printheads – inks pour on paper sheet-wide while the sheet passes under printheads. That results in accurate ink application and maximum print speed.

The devices built on this technology use Vivera inks to provide highest print quality even on plain paper. Unlike jet technology, inks don’t diffuse into paper, but are applied on its surface and fixed with fixing agent to form a thin film. As a result, printouts come out dry even at high speed.

HP Edgeline Technology is developed for high-volume printing systems used in commercial print, industrial and office large-volume print. First products built on Edgeline technology are expected to appear the soonest.

ISO Suggests New Method for Assessing Print Cost

Until recently, no one actual knew how much a single print costs. Every manufacturer has it’s own methods of measure, and information customers had was often far from real state of affairs.

It was in December 2002, that Office of Fair Trading (OFT) addressed the major manufacturers – Epson, Canon, HP and Lexmark – so that they developed a unified technique for assessing ink consumption, printer toner yield, etc.
Currently, the cost of consumables is several times of the printer, during its lifespan. Moreover, the manufacturers not always fully fill a printer cartridge with toner, so that a customer was quicker to come for the next one.

OFT affords resulted in new technique of assessment developed by International Organization for Standardization (ISO) in cooperation with mentioned above brands. The technique provides for compulsory testing
  • under standardized temperature
  • on several type of paper
  • several units of same printer model
  • with several sets of cartridges


ISO suggests that manufacturers use this technique starting from now, despite it’s now approved as a standard so far. However, only HP and Epson have applied the technique, Lexmark is planning to do so at the end of this month. Canon has not yet responded to ISO recommendations and is using its own methods.
