Which computer printed

This article also describes a few of the projects that have already succeeded in using ink jet printers to create transistors, actuators and linear-drive motors. Few argue that the next generation of computers will be nearly invisible, meaning that they will blend in with everyday objects. Flexible ink-like circuitry will be printed onto plastic or sprayed onto various other substrates, such as clothes.

Jacobson has said that his group will be able to produce a simple printed microprocessor in late or early He also foresees being able to eventually produce a printed chip that could rival an Intel Pentium processor. Jacobson's group has already succeeded in using an ordinary Hitachi ink jet printer to make several components for a printable computer. Using a nanoparticle-based ink made from suspending nano-size semiconductor particles in a liquid, researchers spray the components onto a plastic substrate.

Here's a look at some of the printed components the MIT group has made with this process:. For that, polymer stamps are used with the architecture of the transistors in a positive relief. The stamp is then dipped in the nanoparticle ink and transferred to a substrate by hand. The next step will be to use an ink jet printer or some other kind of desktop fabricator to create printable transistors.

MIT isn't the only group developing ways to print computer circuitry. Plastic Logic , a company that sprang out of work begun at Cambridge University in England, plans to market the first plastic chip. The company has developed and patented a method of printing plastic onto polymer substrates, making cheap and flexible plastic transistors.

The process is similar to the ink jet process used by MIT, but Plastic Logic adds carbon-based chemicals to alter the properties of the plastic. By printing the chips onto rolls of film, they can be applied to a variety of surfaces. At Lucent Technologies' research company, Bell Labs Innovations , researchers developed the world's first printed transistor in Using plastic sheets similar to overhead projector transparencies, a liquid plastic semiconductor is applied over a stainless-steel mesh with a squeegee to form the multiple layers of the transistor.

After the solvent of the mixture evaporates, the plastic remains. The process is very similar to how silk screening works. Soon, scientists will be able to create just about every part of a computer's hardware using a desktop fabricator.

Plastic will take the place of silicon for many purposes, but don't expect to write off silicon as a valuable computer component for at least a decade or two. In the next section, we'll see how plastic stacks up against silicon and why we can expect silicon to stick around for many more years. Plastic may revolutionize the semiconductor industry, but it won't be an overnight revolution.

If the printer is turned off, not connected to the network, or there is another network related issue, the printer is shown as offline. Some programs often only older ones may also use the keyboard's print screen or prt scrn key to print. If your program does not work with the previous steps, try pressing this key to print the document or file. Finally, if you can locate the print option, but it's grayed out, or you receive an error, it's likely you have problems with the printer or its drivers.

In some rare situations, a program may not have a print option. If so, you try copying and pasting the information you want to print into a document in another program, and print it that way.

For help with copying and pasting, see: How to copy and paste text in a document or another program. Note Before proceeding, make sure your printer is turned on, and is installed and configured correctly.

Tip To print only sections of text or images, it may be easier to copy the text or picture, and paste it into a document. Note You may need to click More settings or Advanced options before seeing the selection option. Note If you are trying to print to a network printer , you cannot print unless the printer is online. Note In some rare situations, a program may not have a print option. Additional information How to print a picture or attachment sent in e-mail.
