Computer Printers

You can of course get both color and black ink, but all inks also come in normal or high-capacity. Consider how much you use. If you're printing photos consider getting photo ink.

The biggest thing you can do to increase your injet cartridge's shelf life is to not use. Store it in a dry, cool place until it's ready to be used, otherwise it may dry out.

A ink Cartridge for the HP Deskjet 6980 is fairly expensive if you differ it from other printers inkfillings. The ink cartridge costs about 20 dollars and can be found everywere.

It depends on several factors; what brand of laserjet printer toner cartridge you are looking to purchase, whether you if you are looking to purchase a new or refurbished cartridge. Prices vary widely. The most economical way to replace a laser jet toner cartridge is to purchase a refurbished/refilled toner cartridge.

USB cable type is common printer connector

An output is, "the act, process, or an instance of producing" (Merriam-Webster). A printer produces a hard copy of information or data stored on a computer. Therefore, a printer is an output.

An examples of inputs would be keyboards, mice, scanners or other devices which allow for data to enter the computer.

The HP Photosmart C3180 is a good inexpensive consumer printer. I researched, it only costs $199 plus tax. The used one only costs $30 plus tax. Inks not included.

Laser printers use toner cartridges rather than ink.

There are several potable printers on the market that hold from 20 - 50 sheets of paper. This eliminates the need to hand feed each sheet of paper individually. HP and Canon are just a couple of the brands that sells this type of portable printer.

Yes, and you can connect many more devices.

The router should have at least 4 ethernet ports to connect to. And/or you can connect wireless also. If you have more then 4 wired devices then you can use a 4, 8, or 16 port ethernet Switch to connect to the Router.

Myself I have 3 desktops (wired), 3 wireless and 1 wired laptops, an X-Box 360 (wired), a Wii (wireless), a BlueRay player (wireless) and a Brother laser printer (wireless) connected to the router. (1 desktop, 1 laptop and the X-Box are hooked to the Router and the rest of the wired devices are connected to an 8 port ethernet Switch which is connected to the Router.)

The bigger the data bus, the more data can be fetched in one go and processed, making the computer faster

A printer cable can connect to a serial printer using a 25-pin "RS-232", DB-25 connector, among other things. In many cases, only a few pins of the defined 25 pins are used (e.g., send, receive, common). There are also adapters that convert between the 25-pin connector and, say, RJ-11 phone cord, RJ-45 Cat 5, or even screw terminals for 3-conductor cable, or what-have-you, for connection to the computer (e.g., a DIN-8 in a Mac), or a converter for USB to RS-232.

If it is a Male connector on PC it will be 25-pin Serial Port, If it is a female connector (purple colored if latest) it is parallel port, sometimes called Printer Port(LPT) - Naresh , InfoMax

While HP has many printers that support PostScript drivers, the HP L7580 does not appear to be one of them. HP provides a list on their website of which of its printers are PostScript compatible.

It is during the developing phase of the laser printing process that toner is applied to the latent image on the drum. The toner is a negatively charged mixture of plastic and metal particles.

Line printers as well as serial dot matrix printers use pins to strike against the inked ribbon, making dots on the paper and forming the desired characters. The differences are that line printers use hammer bank (or print-shuttle) instead of print head, this print-shuttle has hammers , and these hammers are arranged in a horizontal row .The hammer bank uses the same technology as the permanent magnet print head with the small difference that instead of print wires the print-shuttle has hammers. The printing mechanism works as follow. The permanent magnetic field holds the hammer spring in stressed, ready to strike position. The driver sends electrical current to hammer coil, which then creates electromagnetic field opposite to the permanent magnetic field. When both fields equalize, the energy stored in the spring is released to strike the hammer against the ribbon and prints a dot on the paper.

Most carbonless paper will not work with laser printers since lasers burn the image onto the paper instead of pressure. They usually only work with paper that is similar to the carbonless paper.

plug the printer's cord into the laptop's USB port

Advantages and Disadvantages of Textile Laser Cutting

Cutting textile into pieces is one of the crucial stages in the process of soft material production. It’s only after the cutting of the materials that they can be sewed or heat pressed into desired shapes and sizes. One of the very popular methods of getting it done is the laser cutting process. With proper use of good quality laser parts, laser cutting process can be very effective and low cost.

At the same time, it does have a few downsides as well. So let’s explore those great qualities and disadvantages more closely.

What Are the advantages of Laser Cutting?

The reason why clients prefer laser cutting more and more lies with the long list of upsides it offers. The advantages of laser cutting are flexibility, precision, repeatability, speed, cost-effectiveness, great quality, contactless cutting, material saving, versatility and automation possibilities.

Flexibility

Laser cutting offers freedom for the design and the quantities of product. Indeed, you can choose anything! For the design, once you have your software and respect the material design guidelines, you can do anything. There is almost no constraint while using this manufacturing technique. And no matter if you want to customize one piece or massive thousands of pieces, you can all use this laser technology to have same cutting cost and no extra model needed.

Precision and Material Saving

The highly accurate and precise nature of cutting is one of the greatest benefits that lasers have brought. It allows for highly accurate cuts that leave a clean cut and a smooth finish. This vastly reduces the amount of material wastage that has been seen in the past.

Reduced Finishing Requirements

Because laser cutters produce highly precise cuts, they will lead to fewer necessary finishing requirements. Edges produced by a laser cutters are smooth and free from burrs. The beams are also tightly focused, meaning there will not be internal flaws from heat exposure. Because laser cutters will produce high-quality, precise cuts, quality checks will take less time.

Quality

As laser spot size is very small and the repeatable precision is very high, each cutted pieces’ size and shape are same and it makes the next sewing or pressing process much easier and the final product very high quality.

Contactless Cutting

This means that the laser beam used doesn’t physically touch the material that it is working with, instead causing the melting and cutting process through heat. This means that damage to the material is minimized and the shape is exactly as the original designed.

Labor Saving

Due to the easy operation of the laser cutting machine, the operator only need to take care of the cutted patterns pick-up job. Generally one worker can take care 1-3 cutting machines due to different product. It will reduce a lot of pressure of finding experienced worker and can save you a lot of cost.

What Are the Disadvantages of Laser Cutting?

And because not everything can be good, here are what we considered disadvantages:

Thicker materials are more difficult to cut or require very low speeds.

Multi layer material cutting mode is not suggested due to the contaminated cutting edge.

The laser beam is powerful and can cause some burns if it accidentally comes in contact with human workers.

Some composite material with glue inside or PU or authentic leather will have some yellow edge due to heat cutting.

While you can find other cutting methods which are inexpensive and being preferred since a long time, you cannot ignore the plus points that laser cutting has to offer. The quality of cut that laser cutting provides can hardly be achieved by other methods available for carrying the process.

I am new to the computer and would like to hook up my hp all in one printer to my older iMac computer. Something I read said to change my settings to default. I don't know how to do this. If someone could explain to me in easy step by step details I would be very grateful. Please help. Elizabeth Bednarz

There are multiple interfaces / cables that have been used to connect printers to a computer, each with a different number of wires. USB, for instance, has only 4 wires, while IEEE 1284 (parallel / Centronics) has 25 pins, although not all of them are always used for all printers. IEEE 1394 (FireWire) has either a four or six-wire cable, while the ADB (Apple Desktop Bus) port used 4 wires.
