What’s 3G, 4G, LTE Wireless Technology ??

Posted on

The difference between 3G and 4G technolgy is speed.  3G is third generation, which is what most wireless technology use and 4G is fourth generation; which just makes it more powerful.  If you’ll recall, 1G and 2G came before, with each one becoming faster, more secure and reliable.  So, getting a 4G wireless router means it should perform at the highest level. We are talking must faster data transfer speeds.

  1. 3G

The standard for 4G must be around 100 Megabits per second and up to 1 Gigabit per second.   However, it might be confusing, but 4G is not true 4G – yet.  True 4G is not expected until late 2013.  On 3G/4G devices, the speeds are somewhere between 3G and 4G.  Probably when you start to see aggressive marketing for 5G, you’ll have true 4G performance.

Also, you might see the term LTE 4G – LTE stands for Long Term Evolution.  It is simply a version of 4G.  Right now, the International Telecommunications Union regulates the standard for 4G wireless technology.  To make it more confusion, according to this governing body, LTE Advanced and WIMAX Release 2, are the only two formats that should be called true 4G. Long Term Evolution, Super 3G.

Color Laser Printers, Is it good for Photographs?

Posted on

Color laser printers are a comprehensive choice for the person who wants to print in as many forms and ways as possible. They can produce a very high quality print and can easily print a mix of text and images. Furthermore, color laser printers are almost unlimited in their capacity to print designer fonts. Not only do they come with a standard set of fonts, called resident or internal fonts but you can also add fonts.

One way to add fonts to your color laser printer is to add a font cartridge. Almost all models of high quality laser printers have slots that allow you to insert font cartridges into them. These font cartridges are ROM boards on which font types have been stored. The plus to using a font cartridge is they do not use up your printer’s memory.

You can also print soft fonts using color laser printers.  This is through a process that is called “downloading fonts.” All laser printers are sold with a certain amount of RAM memory. You can increase this memory by adding memory to the printer’s expansion slot. These can then be copied from a disk to the printer’s RAM. The more RAM available on the printer the more fonts you can download onto your printer at one time.

In addition to text, laser printers are very adept at printing graphics. However, you need a sufficient amount of memory to print high-resolution images and graphics. However, you need significant amounts of memory in the printer to print high-resolution graphics. For example, to print a full-page graphic at 300 dpi, for example, you need at least 1 MB (megabyte) of printer RAM. For a 600-dpi graphic, you need at least 4 MB RAM.

All-in-one Laser Printer, Scanner, Fax and Copier

As these machines all share the same type of photosensitive electronic technology it is quite easy (and also a good idea) to get an all in one laser printer, scanner, fax and copier. For one thing you will be spared the cost of getting all four different machines and instead be able to buy one unit.

Another great thing about buying an all in one laser printer, scanner, fax and copier is that it really helps you save on the amount of space that you have in your office. Formerly all four of these machines could be taking up a lot of space on your desk or even be using up the surface space of a couple of desks.

Yet another benefit is the amount of money you will save on print cartridges. Instead of springing for a different type of cartridge for each brand of machine you only need to buy one. You can also save quite a bit of money on paper, mostly because laser printers will print on just about any type of paper.

The only drawback when it comes to investing in an all in one laser printer, scanner, fax and copier is that they can be quite expensive. This is why they are usually found only in commercial or business offices.  http://www.bluechipstech.com is the website which has lots of information about laser printer. Check it out now for more information.

However, these all in one laser printer, scanner, fax and copier units are much less expensive if you opt to buy a black and white laser printer as opposed to a color laser print. The price drops even further if you buy a model that does not use a real laser as part of its function but instead the much cheaper LED or LCD system.

If you do end up springing for the color version, then keep in mind that one way to save money is to always keep it in black and white mode unless you absolutely need to print a document in color.  This way your laser printer cartridge and printer toner will last a very long time.

Color Laser Printer – Will it Print Photographs?

One of the biggest questions that people have when they first set out to purchase a color laser printer is “Will it print photographs?’  This is the type of question that can only be answered with another question “What kind of quality do you want your photographs to have?”

Purists would simply be compelled to answer the question “Will it print photographs?” with a flat no. Color laser printer simply do not have the power to replicate a high-resolution photograph simply because they only print on one kind of paper. In order to print high-resolution photographs, you need a pricey inkjet printer that can print on photographic quality paper.

However, if all you are looking for is a photograph with skewed color, much akin to the kind of image you might get out of a color Xerox machine that has not been adjusted quite right then by all means go ahead and print photographs using your color laser printer. However, do not expect very high quality and lots of bleary edges as well as off colors.  The problem is that color laser printers simply do not print off enough dots per square inch to replicate the photograph properly.  There is simply not enough gradient in terms of light and shadow in the entire process to recreate photos in a realistic way.

Every printer you look at will have a resolution specification. This specification reveals how much detail a print can reveal.  The rating consists of two numbers. Something like 4800×1200 dpi. That “dpi” term means “dots per inch” and refers to how many points of color (or pixels) a printer can transfer to each inch of paper. The higher the number the more detailed the image, the better its quality will be.

So when it comes to printing out photographs you should forget about color laser printers altogether and go for one of the hundreds of high quality jet ink printers on the market that can easily print out a photograph.
