Comparison Epson L805 vs Epson Stylus Photo P50

The maximum number of pages that the printer's ink (toner) can print. The value is rather conditional, in reality the deviations from the norm are very large (up or down). In inkjet printers, the cartridge life is relatively small and amounts to several hundred prints. In laser and LED devices, the bill is already in the thousands.

The maximum number of pages that the printer's ink (toner) can print. The value is rather conditional, in reality the deviations from the norm are very large (up or down). In inkjet printers, the cartridge life is relatively small and amounts to several hundred prints. In laser and LED devices, the bill is already in the thousands.

The printer has a built-in CISS — a continuous ink supply system.

The essence of such a system is that the ink for printing is not in the cartridge, but in external containers, from where it is supplied to the print head as needed. This provides a number of advantages over traditional cartridges. Firstly, CISS containers hold much more ink and need to be refilled less frequently. Secondly, refilling the CISS in terms of one print is much cheaper than "recharging" and even more so replacing the cartridge. Thirdly, dyes of different colours are refilled into such a system separately, and when ink of one colour is exhausted, it is enough to replenish only their stock (whereas some colour cartridges need to be changed completely, even if only one of the colours has run out).

Note that CISS can be installed separately; however, the factory setting is more reliable, such devices are less likely to fail. At the same time, this feature significantly increases the cost and complicates the design of the printer. Therefore, it is worth paying attention to models with built-in CISS first of all if you plan to print often and in large quantities.

— Pigment. Ink based on pigments — solid dyes, which are diluted in the form of microparticles in a liquid filler to a state of suspension. Compared to more popular water-based inks, these formulations are noticeably more expensive, and the finished image may turn out to be somewhat less bright (compared to printing with water-based dye on the same printer). On the other hand, pigment ink gives higher detail, which is especially important for photo printing. In addition, finished images resist moisture better and do not fade as quickly in bright light — this resistance is not enough for outdoor use, but indoors such prints can be stored for a very long time.

- Water soluble. Inks based on water-soluble dyes allow achieving high realism of color reproduction in color printing, they are well absorbed into the deep layers of paper and are cheaper than pigment ink. Also, water-soluble ink does not dry as quickly in the cartridge or print head of the printer. They are recommended for use with inkjet paper - ordinary thin paper strongly absorbs dropsy, which can cause ink to show through on the back of the sheet. At the same time, water-soluble inks are afraid of moisture and direct exposure to ultraviolet rays - when water gets in, the paint “floats” on paper, and it fades under sunlight.

– Pigmented / water soluble. Some printers have a print head that allows you to print with two types of ink at once. A common case is when their black cartridge is filled wi...th pigment ink, and the color one is filled with water-soluble ink.

The number of ink cartridges required for the full operation of the printer. In black and white devices, usually, one cartridge is installed. For colour printing, at least 4 colours are required (CMYK colour scheme), however, cartridges in such devices can be installed as 4 (one for each colour), or only 2 — black and "colour". The latter is essentially three multi-coloured cartridges in one case; This design somewhat reduces the cost, but creates certain inconveniences: when the supply of ink of one colour is exhausted, the entire colour cartridge becomes inoperative. However, this disadvantage is not critical if the possibility of refueling is provided.

Printers designed for more than 4 cartridges are also available. This design means that this model uses one of the extended colour schemes; this, on the one hand, contributes to high-quality colour reproduction, on the other hand, it significantly affects the price. In the most advanced photo printers, the number of cartridges can reach 9.

The types of cartridges (both black and white and colour) used in the printer. Some printer models are able to work with "non-native" cartridges, but this feature usually refers to undocumented features, and the manufacturer's warranty covers only specific types of cartridges. So use "non-native" models with caution.

— Connection to PC (USB). Possibility of wired connection with PC via USB interface. Do not confuse this function with the USB connector described above: in this case, the peripheral device is the printer itself. This option is the most popular way of wired connection to a computer nowadays: there are USB ports in almost any PC or laptop.

— Network connection (LAN). Possibility of wired connection to a local computer network through a standard LAN connector (using an Ethernet cable). With this connection, the printer becomes available to all computers on the network — this is very convenient for offices, co-working spaces and other places where different people have to use printing from different computers. Note that the connection to the network can be carried out both through one of the computers of this network, and through a common router; in the second case, the printer remains operational regardless of which computers on the network are currently turned on. Compared to another connection option — Wi-Fi — a wired connection is less convenient due to the need to run a cable; however, it is cheaper, and the connection is as reliable as possible.

— Wi-Fi. A wireless technology that was originally designed to work with computer networks, but nowadays is also used for direct communication between devices ( Wi-Fi Direct, see...below). Usually, printers with Wi-Fi can work as network devices — when communication is carried out via LAN, and all computers on the network have access to the printer; but the possibility of direct connection of gadgets is less common. However, the specific functionality of Wi-Fi anyway needs to be specified separately.

— Card Reader. Slot for reading memory cards, usually, with the function of direct printing (see above). In this case, this function is convenient primarily because memory cards are widely used in modern photo and video cameras; thus, the card reader allows you to quickly and conveniently print the footage — just remove the card from the camera and install it in the printer. However, this function can be useful for exchanging data with other devices — for example, laptops; and in some printer models it is even possible to work in the mode of an external card reader for a PC.

— USB. USB connector that allows you to connect various external peripherals to the printer. Most often used for direct printing from flash drives and other drives, however, it can also be used for other purposes — for example, for updating firmware, diagnosing problems, etc. Do not confuse this function with connecting to a PC via USB when the role of a peripheral device is played by the printer itself (see below for details).

— Bluetooth. Direct wireless communication technology between different devices. In printers, it is used mainly for the traditional purpose — to receive materials sent for printing from external devices. One of the advantages of such a connection is that it allows you to work not only with computers, but also with portable gadgets like smartphones and tablets: built-in Bluetooth modules for such gadgets are almost mandatory, but wired connection methods are most often not available at all. Yes, and it can be more convenient to communicate with a PC or laptop in this way: Bluetooth does not require wires and works confidently at a distance of about 10 m.

— NFC. Short-range wireless technology — up to 10 cm. In printers, it is usually used as an auxiliary function to simplify communication via Wi-Fi and Bluetooth: instead of setting up the connection manually, just bring an NFC gadget to the printer and confirm the connection. And in some models, in this way (by bringing the device to the printer), you can even immediately send materials for printing; To do this, usually, you need to install a branded application on an external gadget.

— Wi-Fi Direct. A feature found on models with built-in Wi-Fi modules (see above). Direct support allows you to connect other Wi-Fi devices (laptops, smartphones, cameras, etc.) to such a printer directly, without using a router and a local network. This can be especially convenient if there is no network equipment, or if it needs to be additionally configured. The functionality of the Wi-Fi Direct connection is generally similar to Bluetooth (see above); the main difference is that Wi-Fi provides a faster and more reliable connection, with longer range. This is especially true when transferring large amounts of data — for example, sending large documents for printing. In addition, such a connection is better suited for direct printing from cameras — Wi-Fi is traditionally used for wireless connection in this technique.

— AirPrint. Same function as above (Wi-Fi Direct). Allows you to connect to the device without using a router. However, in this case, we are talking about connecting Apple equipment — iPhone phones, tablets, Mac laptops.

Cloud print service supported by the printer. Specified only if the device is capable of working with cloud services directly without connecting to a PC.

The general principle of such printing is that documents sent for printing are stored on a server on the Internet. Thus, the availability of the printer is not limited to the local network — you can send documents for printing from anywhere in the world where there is access to the World Wide Web. In addition, cloud-based printers make it easy to share with others.

The number of sheets of paper that the output tray can hold — the tray where the finished media is delivered. Usually, this amount is specified for standard office paper with a density of 80 g/m²; if you use thicker sheets, the actual capacity of the tray will be less (conversely, thinner sheets may fit more).
