Deskjet Review

What is the difference between hp deskjet and officejet?
some told me that officejet is used with huge jops
some told me that officejet can be used for sublimation

The officejet series is for Business and can handle big jobs. They are also, more expensive. They are either Laser or Ink jet printers (not sublimation).

A colour laser allows you to print different documents such as photos, graphics or even text in colour.
A quality colour laser is an expensive device. The laser printer uses a laser beam, which places different electric charges on a rotating drum. This drum transfers the toner to the paper.

The ink jet printers function differently, by spraying ink on the paper and they need to be recharged when the ink is exhausted. There are some low-priced ink jet printers that are intended for home use, but they print only a few copies a month and the ink replacement is quite expensive.

When buying a colour laser you must decide the intent for the device. Will you need a small amount of colour printouts? Or will you rather need more copies? If you need to print banners and documents of bigger size, you will probably need a quality colour laser.

The memory of a printer is important, as it is responsible for the speed of the printing. For black and white texts, the memory is not essential, but for quality printed images the memory should have at least 128 MB of RAM. Also check if the memory can be upgraded.

Then you should consider the speed of the printer. This speed is measured in pages per minute, but this feature is not highly important when deciding on the laser colour you want to buy. Look out because the speed that is written on the user’s manual is not entirely realistic, and may not correspond, so you should think that it is a bit lower than the manufacturers say.

Next, consider the volume the colour laser printer can take. Find out the monthly figures the printer can handle, and compare it to your approximate volume of printed material. It is best if you buy a printer that can print by 25% more that your estimated number of pages per month.

The resolution is an important feature of the colour laser printer. The higher the resolution, the better the quality of the printed page. This feature is relevant in case you want to print out photos or images. For text printing you should choose a printer with at least 600×600 dpi, while for images a minimum of 1200 dpi is recommended.

The colour lasers print on practically any type of paper. However, the quality and the aspect of the printed page differ according to the level of absorption of each paper in part. You should test a few types of paper and decide on the one that suits your colour laser best.

Some people don’t find it essential to print in colour. People usually want a printed page for its contents and rarely for the colour of it. However, when you need to print out a photo or an image it is very important that you have a colour laser printer that will render the image as it should be. A colour laser printer is recommended for departments such as graphic design or marketing.

Ink cartridges, laser toner cartridges, or printer ribbons; are all an integral components of printers systems, without which all printers are practically useless. These are the components through which the end product of printing is visible to us. These components contain the ink, which spreads on the paper during the process of printing. The market is replete with a wide variety of cartridges manufactured by different manufacturers and that can be used in different types of printers.

The Concept of Similarities and Dissimilarities

When you talk about cartridge’s one must understand that there are quite a number of similarities between the composition, structure, and usage of the three cartridges. After all the basic concepts between the designs remains similar and only a few minor changes distinguish them from each other. However, one must also understand the fact that there similarities does not mean that they use can be interchanged. Ink cartridges can only be used in ink jet printers.

The Similarities

Typically there are two separate cartridges that are inserted into the printers, one is a colored cartridge filled with the three primary colors while the other is a black cartridge. In laser toner cartridges there is no ink but there is a toner which is a material that facilitates laser printings. However, the coloring parameters remain the same.

Both ink cartridges and the laser variety can be refilled and thus users can save money on the cost of buying a whole new cartridge. Even printer ribbons can be refilled; however, the process of refilling will differ.

Differences

Apart from the technical differences associated with the three cartridges, and the process of printing in general, there are differences related to the quality of the print, cost, and speed of printing. When it comes to printing speed printer ribbons are the slowest of the lot while cartridges using laser toners are the fastest. Moreover, with regards to cost, the cartridges for laser printers are more expensive than their ink based counterparts. This is because the cartridges for laser printers offer the best printing output and are faster than the other cartridges. One can take out a large number of print outs of the same superior quality unlike in ink cartridges wherein the results start getting blurry quite quickly on account of the ink running out.

None is better than the Other

If you look at the similarities and differences, you will see that you cannot judge the cartridges based on them. You cannot say that one is better than the other, as it’s completely your choice as to which printer you own and thus the cartridges that you are going to use. Experts will tell you that laser toner cartridges are the best amongst the three, but for that you must have laser printers, which in itself is expensive and so are its cartridges.
