Comparison Canon PIXMA IX6850 vs Canon PIXMA iP8740

The color palette that the printer can print. A large number of colors is required for high-quality photo printing and obtaining color prints with many shades. The standard is 4 colors.

The black and white print speed provided by the printer. It should be noted that this parameter is often indicated for low quality when the device is running at maximum performance; at a higher quality (even at standard), the actual speed can be noticeably lower, so you should choose with a certain margin. Also note that high speed significantly affects the price, power consumption and noise level. Therefore, it does not always make sense to chase maximum performance — for simple applications (for example, at home or in a small office), a relatively slow and inexpensive device may be the best choice.

As for specific values, speeds up to 20 ppm are considered relatively low, 20 – 30 ppm — average, 31 – 40 ppm — decent, and the fastest models are capable of delivering more than 40 pages per minute.

The maximum number of pages the printer can print in a month while still operating at full capacity.

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 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.

— Voice assistants. Printer support for one or more voice assistants. The most popular voice assistants among printers today are:

• Amazon Alexa
• Google Assistant
• Microsoft Cortana

We emphasize that this is usually not about the voice assistant built into the printer itself, but about improved compatibility with external devices where such an assistant is installed — so to use this function, you will also need an appropriate device. However, the ability to give voice commands to the printer significantly expands the control options, making it more convenient and intuitive; but the specific functionality and features of different voice control systems may be different. For example, Amazon Alexa is available both through special control devices (like Echo smart speakers) and through mobile applications for Android and iOS; Google Assistant is part of the Android OS and Google Home smart home systems; and Cortana is designed primarily for use with Windows PCs and smartphones, although it is also available as an Android application. The set of supported languages can also be different (in particular, English is almost always available, but Russian support should be specified separately).

— Printing on optical discs. Ability to use the printer to print directly on recordable optical discs (CD-R/RW, DVD-R/RW). Thus, after recording a disc, you can put on its non-working surface (non-mirror side used for inscriptio...ns) an inscription or image as you wish. Often these printers come with software that makes it easy to create layouts for printing on disks. Please note that only specially designed discs can be used for printing.

— Printing on roll paper. Possibility of using for printing paper in rolls. Thus, the print size is limited by the width and length of the roll, which allows you to create materials other than ordinary A* sheets. Large-format paper and photo paper can be supplied as rolls.
