There are many types of printers, so it is difficult to find the model that responds more to their needs.
For your convenience, the characteristics of some printers are presented.
The main advantages of a laser printer is its speed and its printing costs.
Monochrome laser printers
Suitable for office work, monochrome laser printers are capable of processing about 5000 pages per month and are compact enough to be installed on a desktop.
-Group of printers networks meet the needs of two to ten users.
-The departmental printers are shared among many users and are equipped with technologies to process large volumes and withstand constant use.
Color laser printers
-The single-pass color laser printers from printerhall: enable a color print in one pass through its four drums, one for each of the elementary colors (Cyan, Magenta, Yellow and Black). Widespread, these laser printers print in color as fast as black and white (up to 45 pages per minute) and are all indicated for intensive use of color.
-The multipass color laser printers: based on technology a drum for a toner cartridge (4 in all). The color printing requires several passages which significantly slows down the process. However, for grayscale prints, its performance is excellent.
Multifunction laser printers
Able to handle all office tasks, multifunction laser printers combine the functions of photocopiers, scanners and fax machines (with management numbers and store faxes).
Only in color version, the ink jet method for printing on a variety of media. Versatile and economical to buy, they are less consumption.
-Continuous inkjet technology: is to continuously eject drops from the print head and deflects the portion toward the paper by magnetic coils. The rest of the ink is recovered and recycled for a new jet cycle.
-Drop technology to the application: only use the drops required for printing. This is the most used office technology. It provides good print quality despite a slower rate than the continuous stream. It is also found on the market, in the same category, multifunction printers inkjet individual or collective use.
Large format printer
High-speed printing devices, large format printers can print in color on paper sizes larger areas (A1 or A0 for example).
-Oriented technical printing: they meet the printing needs plans and charts ( line precision, speed, print quality)
-Oriented graphic art. they are developed for image printing needs and events in high definition color printing formats of wide format printers are: A2 ( 42cm wide), A1 (61cm wide), A0 or A0 + (91 to 112cm width), 60 inches (150cm width) .
Dot matrix printers have a printhead consists of a series of pins, driven by electromagnets, impinging on a carbon ribbon called “ribbon”, located between the head and the paper. The carbon ribbon is scrolled so that there is constantly the above ink, it circulates in a loop between the print head and the paper. Each needle can print a tiny dot on the map, each character is made up of multiple points. At each end of the line roller rotates the sheet. This mechanical head system has the disadvantage of a reduced speed in the unfolding of tasks. However, dot matrix printers are very robust devices. The number of needles may vary from one printer to another (from 9 to 32 in general), the print quality is proportional to the number of needles.
This technology allows printing on carbon sets allowing to have an immediate duplicate of the document.
Intended for a specific use (receipt, ticket …) the ticket printer is easy to use, robust and small. A thermo-printing procedé acts by heat on a heat-sensitive paper. At the time of printing, the ink passes integrally on the carrier and the tape is thus usable only once. The range of printable media is high as can be printed on matt or glossy paper, packaging films, textiles …
The selection criteria
To select the print speed you need, refer to the annual needs of impression of your business. The more you print more your machine must be robust and effective response to storing paper.
This criterion is essential for an impression of quality and support diversity.
The printing precision is measured in dots per inch and varies a black and white or color printing.
This is the time it takes the printer before the start of printing.
The printer memory
It measures the amount of information waiting to print the printer can keep in his memory. If the printer must meet the demands of many users or deal with complex documents, the RAM must be absolutely important. Some printers, such as large format printer can accommodate a hard drive or print server when not using your workstation to receive print jobs and queues.
The paper size
The maximum size of the sheets that the printer can accept.
The type of paper feed
-Tray or “tray” uses a large internal storage
-The tray uses her external storage, a small amount of leaves (50 to 100). The ability of a tray varies if you have a printer personal or departmental model dedicated to producing thousands of pages a day.
The substantial autonomy of the toner cartridge avoids having to change too frequently consumables. It is calculated by the manufacturers based on pages covered to 5% (European standard). It can be significantly less in the case of denser materials including graphics and images.
The capacity of the cartridges varies by model and product family (1500/2500 pages for a personal printer, 6000 pages for a group printer) .
For intuitive operation, the control panel must be complete and clear (easy to spot keys) and the main options must be directly accessible.
Connectivity and sharing
Serial, parallel, USB, WiFi or Ethernet, most printers are able to be shared on a LAN.
Other physical characteristics such as size, weight and noise level can also be taken into account in some cases.
