How to choose the printer?
|/img >/img src="//images/stories/tip/comp-progs/printer-choice-1.jpg" alt="How to choose the printer?" title="Как выбрать принтер?" align=left /> The printer is a device for listing of the text and various images. It is useful and at office for the printing of various important documents, and at home – for the printing of different pictures, photos, culinary recipes or lyrics... How to choose the printer?|
Printers, despite the increasing popularity of the MFP (multipurpose devices), are still in great demand. After all the device developed for performance of the one and only task will always carry out it much more qualitatively, than in what similar task – only one of many.
Choosing the printer, it is necessary to be defined, first of all: what sort information needs to be printed out. After all possibilities of different printers concerning the printing of the text and graphics, photos with high quality or the press on different carriers are various. Thus, if it is most often necessary to print out, for example, text documents, it is possible to be limited to inexpensive model, without possibility of the color press.
One more important parameter – a so-called format of the printer. It is defined by the maximum format of paper for which the press is possible. Traditionally the gradation is conducted according to the international formats of paper from A0 (the biggest format) to A6 (smallest). The A4 format – the most widespread in offices and in life. Its sizes – 210*297 mm. The A3 (297*420) format is less often applied.
At a choice of the printer it is also worth paying attention to possibility of the color press. The color press is irreplaceable if it is necessary to print out pictures and presentations, color photos.
Depends on quality of the press, the image on the printed-out document will be how accurate. This parameter in number of dots per inch – the their is estimated more, the quality of the press is higher. For the text there is enough permission in 300 dots per inch (dpi), and here photos require at least 1200 dpi.
Speed of the press can also play an important role at a printer choice. Speed of the press can be measured in pages in a minute (pages per minute - ppm). At the printing of black-and-white or color documents speed can differ. High-speed printers are necessary generally for office work where it is necessary to print out documents often and in large volumes.
Possibility of the printer to print without fields is also important for photos or drawings. If the printer is got not for the ordinary home PC, the great value at a choice of suitable model can render existence of special ports for connection to the computer: USB, LPT, LAN, WI-FI, SCSI.
Except the cost of the printer at a choice of model it is important to consider also the cost of expendables: papers, ink or toner, cartridges, etc. After all if expendables cost very much, and it is necessary to print constantly in large volumes, the cost of the printing of each separately taken page increases.
Inkjet and laser printers enjoy the greatest popularity now, it is possible to meet the matrix less often. What advantages and shortcomings of each of these technologies?
Matrix printers in spite of the fact that they are considered outdated, and are successfully used to this day in financial institutions, in accounts departments, in production rooms. In matrix printers the image is formed by means of the small printing needles which, hitting the painting tape, in the right places leave on paper small points.
It is possible to carry very low cost to advantages of matrix printers account materials. This type of printers has more than shortcomings. They print slowly, is noisy, only b/w (but there are exceptions – quadricolour matrix printers). Thus by no means it is impossible to call the price of matrix printers symbolical.
Inkjet printers are most widespread in house use, are often used at offices. The principle of the press of inkjet printers consists in drawing on paper of liquid ink which form the image. Ink is applied by means of the special snuffled.
Among advantages of inkjet printers: both the color, and b/w press, high quality of the press, satisfactory speed of the press (10-40 ppm), low noise level. The prices of inkjet printers of middle class are quite acceptable though the press are of printers with "photo quality" slightly more expensive.
Expendables for inkjet printers there is enough road therefore for large volumes of the press them it is unprofitable to use. Besides, if the printer did not print a long time (more than 1-2 weeks), in nozzles of the printing head the remains of ink can dry up. Cleaning snuffled from these remains leads to additional expenditure of ink.
Laser printers found the calling in office press. Special powder – a toner – moves on a magnetic drum and sticks to heated paper in the right place.
Carry the high speed and quality of the press to advantages of laser printers, the low noise level, small cost of expendables.
Not really there is a lot of shortcomings at laser printers. First, it, of course, still very high cost in comparison with other types of printers. Laser printers mainly monochrome. Color models cost very much and are seldom applied to daily nonspecific work.
When using laser printers it is necessary to remember that the sprayed toner is unhealthy therefore it is necessary to air regularly rooms in which these printers are installed.
