- Compared to inkjet printers, the cost of purchasing the device itself from laser machines in most cases will be slightly higher. The most popular models for home and office cost from 4200 rubles. up to 60 up to 10500 rub.
- The cost of purchasing toner, as well as the number of printed pages associated with this figure, is highly dependent on the manufacturer and specific model. Compared to inkjet printers, these figures are usually about the same or slightly higher.
Power consumption of laser printers
- A much more important parameter is the level of energy consumption of laser printers. With an average device power of 300 to 550 W, the power consumption is relatively high. Business-class devices consume up to 1000 watts. Inkjet printers with their 25 watts they look much more energy efficient.
- When you first turn on the laser printer, the device must first "warm up". This printer requires a temperature of about 200°C to operate. Thus, those who print little and infrequently receive higher heating costs.
- You also need to pay attention to the level of power consumption in print-ready mode and in sleep mode. Depending on the specific device, they can vary greatly from each other. Sometimes the printer draws less than the modest 10 watts, and other times its appetites point to a wasteful 80 watts.
It should be noted that the power consumption of a printer or MFP is directly dependent on the technology of its operation, brand, and specific modification. In general, in order to decide how much the device will consume electrical energy, you need to study his passport data. Each printer model has its own unique power. In most cases, this parameter is indicated on a special information sticker, which is located at the bottom of the device itself.
The approximate power of a laser printer during active operation ranges from 2-3 kW of electrical energy. By the way, this value is comparable to the power of an electric kettle. Moreover, this is comparable even according to the scheme of operation of both devices. The fact is that the main power consumption of a laser device is during the heating and printing procedure, and this, as a rule, is only a small part of its operation time. Devices that are plugged in but in standby mode consume approximately 10 watts of electricity.
But inkjet printer models have power consumption of up to 150 watts. However, this value can vary greatly depending on the specific brand and model of such a device. Once again, it should be noted that you can determine the exact power of your printing office equipment from the information that is available in the instructions that came with the device or on a sticker located on its surface.
Examples of energy consumption of some models
You can consider the consumption of electrical energy using the example of such a multifunctional device as the Lexmark2300. It’s worth mentioning right away that this model of the device uses a low power consumption mode, which corresponds to the “sleep” mode. This, in turn, has a positive effect on the level of power consumption at a time when the equipment is idle, i.e. not used for printing.
According to test results, the Lexmark2300 MFP consumes about 10W of power when copying a document, while this figure increases to 12W when printing. But during the scanning procedure, this device requires only 6.6 watts. When in a ready state but waiting for a print queue, this MFP draws approximately 5 watts, and when the switch is off, this value drops to 4.8 watts.
Another example is a laser printer such as the HPLaserJet 2300. This technique consumes 426 watts of electricity when printing approximately 25 pages of text every minute. In power saving mode, this value fluctuates between 8.6-9.3 watts. But keep in mind that the time allotted to enable this mode is, by default, at around 15 minutes. But in standby mode, this laser printer, depending on the specific modification, can consume power from 8.8 to 9.6 watts.
In general, in order to independently determine how much electricity a particular model of a printing device consumes, you need to multiply the data from the device's passport by the time it works in one mode or another. At the end, sum up all the measurements, as a result of which you will get the final value of the energy consumption of a particular printer or MFP.

The laser printer contains a large number of resource parts, such as fuser (oven), paper pick-up rollers, separation separators, oscillatory units and gearboxes. As experience shows, the more modern the printer, the less spare parts resource. If earlier the capture roller could work in a printer (for example HP LJ 2200) 120.000 - 140.000 copies, then in modern counterparts only 35.000 - 50.000 copies. The actual resource of fusing units has also decreased by 3 times. It is not a fact that at the right time you will have at hand the necessary VERY EXPENSIVE spare parts, especially competent engineers who are able to repair the printer in a quality manner.
In inkjet printers, the concept of a spare part is ABSENT. For example, HP does not fundamentally repair inkjet printers, but simply replaces them with new printers. Available service centres, as a rule, turn up their nose at the sight of a jet, which is dragged to them for repairs.
In dot matrix printers, the above nightmares are completely absent. Resource parts include only the printhead, which can be replaced by a qualified user. The resource of a head at average intensity of operation makes 3 - 5 years! Lasers can only dream of this!
Delivery time of any spare parts from abroad is 2 - 3 months. Excluding popular and common parts for some Hewlett Packard laser printers.
5. High humidity, atmospheric pressure, dustiness, the presence of aggressive printer operating environments.
Laser printers gravitate toward comfortable (strictly defined) operating conditions. Narrow temperature range. At low temperatures, the oven will not reach the required temperature for baking the toner and the printer will go into an engineering error. If the humidity is high, the toner becomes damp and clotted, as a result, there are problems with the print quality, the fusing and image transfer units fail. In addition, laser printers contain a large number of high-voltage units with voltages up to 3000 volts. In conditions of high humidity, high-voltage breakdowns occur and the electronics fail. Increased dust affects a large number of optical devices in laser printers, optical sensors and especially laser machines. A vivid example of this is the "legendary" printers HP Color LaserJet 2600, 2605, 1600. Due to the dust content of the laser blocks, they basically do not work more than 3,000 copies. Cleaning of mirrors, optics of laser machines is a heavy engineering repair operation
Inkjet printers are quite tolerant of high humidity and vibration, but they absolutely cannot tolerate dustiness, since they include a large number of optical sensors, emitters, and coordinate rulers. The leashes of the inkjet sensors have only counterweights (there are no springs), so the actual position during printing plays an important role.
Dot matrix printers are absolutely not critical to temperature environment and, if necessary, can work even at negative temperatures. They are also not afraid of humidity, there are no high-voltage blocks in their compositions, and the maximum voltage inside the printer does not exceed 30 Volts (Oki Microline 280dc printer). These machines are also not afraid of dust due to the lack of optical sensors and laser machines with mirrors. These machines are not sensitive to external vibration and do not require precise horizontal installation at all. The printer is able to print even if it is turned upside down. Thanks to this feature, Oki ML 280dc can also be used on board aircraft, ships, submarines, spaceships. As a rule, there are two simple mechanical sensors for the entire printer. Consumables in the form of a cartridge with an ink ribbon are so simple that they are not afraid of anything at all. Oki ML280 can be operated even in zero gravity(!) Neither inkjet nor laser printers can be operated in zero gravity.
6. Poor paper quality, its impact on the resource and performance of the printer.
Laser printers are extremely sensitive to paper quality. Paper with poor elasticity (or high humidity) is instantly wound on the thermal rollers of stoves and disables them. Paper with increased abrasive properties quickly erases the rubber rollers for picking up and transporting paper. Even high-quality expensive paper, in a working printer, periodically gets stuck, what can we say about cheap paper or a printer that has been used up in the resource.
Inkjet printers can print on ordinary office paper, however, with dense fills, it begins to warp, the ink begins to blur on the paper. The printer requires special inkjet paper to ensure proper quality. Its cost is TENS times higher than the cost of office paper for laser printing.
Dot matrix printers can work on any paper including writing, glossy and perforated. The cost of the latter is MUCH CHEAPER than ordinary A4 office paper. In addition, matrix printers on special paper can print several sheets at the same time (in several layers).
7. The ability to reuse, refill consumables, protect the manufacturer from the secondary use of consumables.
As laser printers develop, less and less opportunity remains for refilling cartridges. This is facilitated by the protection of cartridges with the help of special CHIPs. The development and improvement of crypto-programs of CHIPs make it impossible to re-manufacture them. Selection of cartridge materials (photoconductors, bearings, magnetic rollers) with a minimum resource that makes it difficult to reuse consumables.
In strings of the HP type, the possibility of reusing cartridges or refilling them is completely excluded due to the presence of a print head in the cartridge. In Epson jets, more and more sophisticated CHIPs are blocking the possibility of refueling.
In dot matrix printers, no one deals with the protection of consumables. And because of the simplicity of consumable design, there is always a choice of alternative cartridges from various manufacturers. In addition, in the original cartridges, you can always repaint the tape with ordinary ink and thus provide them with a second life.
8. Possibility of storage in time of the received prints and influence of environment on them.
Prints on inkjet printers have a minimum shelf life, they quickly fade in the sun, and when moisture (especially water) gets in, they instantly blur and wash off.
Matrix and laser prints are stored for a particularly long time and are not afraid of sunlight and moisture.
From the considered aspects of the operation of printers in critical, difficult conditions, based on different printing principles (laser, inkjet and dot matrix), we can conclude that the only acceptable printing principle is MATRIX.
Recommended printer model for intensive printing in extreme conditions Oki Microline 280 dc.
For non-intensive printing in difficult conditions, we can recommend the inexpensive Oki Microline 1120 dot matrix printer. Its feature is a stationary cartridge with an unusually large print capacity - 4,000,000 characters.

Power consumption in the consumer sense is calculated in kilowatts over a certain period of time. Thus, kilowatts per hour become the basic unit of measurement for the power consumption of a multifunction device.
Power consumption of MFPs of different models in kW
So, how many thousand watts your MFP consumes in one hour is the value of the printer's power consumption. However, before starting the calculation, you should understand that the power consumption of your device depends on the state it is in.
Most MFPs have "on", "standby" and "sleep" modes. On mode is when your printer is actively printing, "idle" is when the MFP is waiting to print, and "sleep" is when the printer is tired of waiting for your print command and is almost off.
Obviously, the "on" mode is the most energy-intensive, and the "sleep" mode is the least. This rule applies to all MFP models. The value of their power may be different.
How to find out what the power is in kW
The best way to learn how to calculate the power consumption of an MFP is with an example. To do this, let's assume that you have an HP LaserJet 4250 printer.
This printer is rated at 5 amps for 230 volt models, i.e. for Australian models. Now the same link shows that the HP LaserJet 4250 print power is 675W, which is 0.675 kilowatts.
Whether you want to consume 1.15 kilowatts or 0.675 kilowatts is up to you.
This example is for illustrative purposes only and is not a certified MFP power consumption value for the HP LaserJet 4250.
The standby power consumption of the HP LaserJet 4250 printer is 20 W or 0.02 kW, while the standby power consumption is 18 W or 0.018 kW. The speed of the HP LaserJet 4250 is 45 pages per minute for letter-sized sheets, which we will take. And it is assumed that your monthly print volume is 100,000 pages. Here comes the calculation.
The power consumption of your All-In-One is:
5 amps x 230 volts = 1150 watts = 1.15 kilowatts
Print volume:
45 pages x 60 minutes = 2700
Your printer prints:
100,000 pages per month / 2700 per hour = ~ 37 hours.
There are a few other situations to consider. First, the printer is idle about 75% of the time it is not printing. Second, the MFP sleeps 25 percent of the time it is not printing.
This means that your printer is on standby for:
720 hours (per month) - 37 hours of printing x 75% = 512.25 hours
This also means your printer is sleeping for:
720 hours (per month) - 37 hours of printing x 25% = 170.75 hours
You are very close to the full and final value of the power consumption of the MFP. It is necessary to multiply the hours worked with the rated power for each mode.
Power consumption when printing:
37 hours x 1.15 kW = 42.55 kW
512.25 hours x 0.02 kW = 10.24 kW
170.75 hours x 0.018 kW = 3.07 kW
Now you can simply add these three values together to get the total power consumption of your printer at work or at home. In this case, the total cost is 55.86 kilowatts. If you want to take it one step further, you can multiply this total cost by any expenses you pay in your area. This will give you the amount of money you pay in your energy bill to keep your printer running.
