What are the best printer brands?
That depends on the type of printer and what is meant by "best". However, the best-reviewed brands are HP (Hewlett-Packard), Epson and Brother. It is recommended one seeks advice at a computer store, since a salesperson familiar with printers would be able to advise one on one's unique situation and find an appropriate printer for one's budget and needs.
DPI means Dots per Inch. The more DPI you have to work with, all else being equal, the nicer your work will look.
DPI Stands for Dot Per Inch.
It has no real meaning on a computer. It is used as a measurement for a printed image. It corresponds to Pixels on a computer screen, but usually there are 4 times more dots per inch on a print, than pixels per inch on your monitor.

DPI can also refer to the sensitivity of an optical or laser mouse.
How is a microprocessors speed measured?
Typically, microprocessors (like the ones found in computers), measure their speed in hertz. A hertz is the measurement of a cycle in a second. So, 10 hertz means 10 cycles per second.
In computing, a cycle (or, more specifically, a clock cycle) is the basic unit of measurement that the CPU uses to carry out instructions given to it by software. Therefore, in a CPU running at 900MHz, 900 million clock cycles will occur per second.
Software sends commands to the processor called, instructions. These commands are the basis for how all programs run on a computer and are handled by the computer in a very complicated manner.
However, a computer running at 3GHz, for example, is not performing 3 billion instructions per second. Some instructions take multiple cycles to complete and some can even have other instructions in the same cycle simultaneously.
To complicate matters further, it is not accurate to say that a higher speed processor is better than another one at a lower speed. Certain AMD processors, for example, run at lower speeds than comparable Intel processors of their family but, because they use different architecture, perform at the same (and, sometimes, higher) performance levels than CPU's with high clock speeds.
Also, processors with some sort of Hyper-Threading technology or, better yet, multiple cores (like Intel Core 2 Duo processors) will be rated at lowered speeds than other CPU's in their price range but, because of more than one (virtual) processor is running parallel to the others, more instructions are performed per clock cycle.
There are also a few more factors to consider but this is the gist of it.
What are the color names used for color printers?
Most printers, like inkjets, use cyan (a shade of blue), magenta (a shade of red), yellow, and black. Some use extra colors including green, light cyan or light magenta. In addition, sometimes there is a "photo black" for printing images, and another black for printing text.
Where can one purchase laserjet photo paper?
One may buy glossy paper for use in a laser printer at Staples, Future Shop or Best Buy. There are different degrees of weight for the paper making some higher quality and more expensive than others.
How do you print something on my computer?
Find the printer icon on the computer (usually on the top left hand corner), and click it. A menu will come up. Make sure the correct printer, color, and size are selected, and press "ok". If there is no icon, press file-or the symbol in the left hand corner on vista-and click print. The same menu will come up, and follow directions above.
The description of a inkjet printer?
Ink jet printing used small drop of ink to print onto paper. These dots are extremely small, and print in a dot matrix pattern on the paper. Different colors of ink are combined together to make photograph quality images.
What printers have the most cost effective ink cartridges?
Usually Wide format printers have the largest capacity of ink. In some cases they have litres of ink attached by hoses to the printheads.
For small office home office you're best off going for Canon or HP... these are the easiest cartridges to refill and generally survive a lot of refills.
The question of capacity comes in, get one of the HP printers that takes the Ink tanks like the #88 from HP or the CLI-8 from Canon. Both of these are easy to fill, have chips of them to keep track of the ink level (they are resettable) and generally are very good quality prints.

What is the main curcuit board in printer called?
It is the control circuitry that includes all the connectors head including the supporting boards also. To identify this i.e. to name it as main board the steeper motor and carriage motor power connection is attached to this board. The main board includes the controller IC/CPU that controls the data buffering. the supporting ICs may transform the data in bit stream to generate the electrical pulses. Only in main board the Adapter power connector is attached which is markedly difference from any dependent board.

What are the advantages of non impact printers?
Non-impact printer does not generate noise during printing because it prints images and text without striking the papers. While impact printer generates noise because it prints by striking print hammer or wheel against an inked ribbon. Non-impact printer's speed is faster and quality is higher than impact printer.
Differenciate between impact printer and a non-impact printer?
Impact printers tend to be noisy while non-impact printers are much quieter. Impact printers use either small pins or characters to strike an ink ribbon and imprint an image onto paper. Non-impact printers use some type of ink that is applied to the paper without touching it. Both laser and ink jet printers are non-impact printers.
There are many different printers which you can buy, depending on nature of your work. If you are looking for a printer for personal use, you can pick from popular models of HP or Samsung. For heavy duty performance, you can use Xerox.
In simple terms - the printer has a vertical line of metal pins - that strike the paper through an ink ribbon, forming the words or images by creating microscopic dots on the paper.
Have a Dell 966 printer Is there a Lexmark cartridge that will work?
The answer seems to be "no" - I bought the Lexmark version of this cartridge, and it doesn't work - the chip on it causes the printer to read "invalid cartridge". Some older versions used an additional slot to differentiate between Dell and Lexmark, but they've now gone down the hardware route and there doesn't seem to be a way around it.
That means you have to order from Dell, and I need to print today. $50 from Office Depot down the drain and no other option. I'm selling this POS printer and buying one from a company that doesn't so blatantly screw its customers.
What is the most expensive hp laser printer available?
The most expencive conusmer printer up-to-date is, probably, 24-carat gold coated HP LaserJet 1160. It was introduced in 2006 on GITEX Exhibition in Dubai. Being one of the kind, this printer is unlikely to be used to do its job - print. But it's still a printer and has its price - $20,000.
The new printer is the IBM Infoprint 2085 and it costs about $30,800.
IS a Canon pixma printer a good choice?
Yes, Canon makes excellent products and their printers are no different. They are kings of the photo world, which means their color use is excellent, and that is what you usually look for in printers, anyways.
How does a daisy wheel printer work?
A Daisy Wheel Printer is an old fashioned impact printer, based on electric typewriter technology. All of the characters (letters, numbers, and punctuation marks) were on spokes radiating from a central axle and somewhat resembled a daisy, hence the name. The printing was relatively slow, but the impressions were incredibly clear as long as there was a fresh printer ribbon.
What is the difference between ink cartridges and laser ink cartridges?
A toner cartridge as the name implies contains toner (a powder) and is meant for a xerographic printer. In contrast an ink cartridge or inkjet cartridge contains liquid ink formulation and is meant for inkjet printer. A printer cartridge is a general term and may be either of the above. For more information see the related links.
