Comparison Epson L6190 vs Epson L655

The color palette that a printer or MFP can print. A large number of colors is required for high-quality photo printing and obtaining color prints with many shades. As a standard, for a color MFP, 4 colors are provided.

Approximate number of pages that the MFP can print in black and white mode without replacing the cartridge. In fact, this greatly depends on the specs of the images to print, so the actual resource may greatly differ from the claimed one in one way or another. Nevertheless, according to this indicator, it is quite possible to evaluate the capabilities of the MFP and compare it with other models.

— 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 inks 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 MFP). On the other hand, pigment ink gives higher detail, which is especially important for photo printing. In addition, finished images resist humidity 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 colour reproduction in colour printing, they are well absorbed into the deep layers of paper and are cheaper than pigment inks. Also, water-soluble ink does not dry as quickly in the cartridge or print head of the MFP. 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 ink is afraid of moisture and direct exposure to ultraviolet light — when water gets on, the paint on paper “floats”, and it fades under the sun light.

— Pigmented / water soluble. Some MFPs 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 with pigment...ink, and the colour one is filled with water-soluble ink.

Cloud-enabled MFPs allow you to work directly with cloud services without connecting to a PC.

The general point of such printing is that the documents sent for printing (and in the case of MFPs, also scanned materials) are stored on a server on the Internet. Thus, the connectivity of the printer/scanner is not limited to the local network — you can send documents for printing and receive scan results from anywhere in the world where there is access to the World Wide Web. In addition, cloud services make it easy to share access to the MFP and other people.

Note that cloud printing can also be used with MFPs, that do not have such a function by themselves — for this, you need to connect the device to a PC with the appropriate software.

The type of display provided in the design of the MFP. This parameter is indicated by two points — colour (monochrome or colour display), as well as the availability of a touch screen(if only spec 'coloured' is indicated, then the display is non-touch).

Chroma determines the features of the image on the display. Monochrome (black and white) displays allow you to show a lot of different information, and are inexpensive. On the other hand, such a display is poorly suited for viewing drawings and photos sent for printing, the results of scanning pictures, etc. — for such purposes it is better to use more expensive, but more functional colour displays.

As for touch displays, they provide additional convenience in management and expand its capabilities. Various controls can be displayed on such a display — sliders, lists, text menus, etc.; operating them with touches on the display is easier than using traditional control panels with hardware buttons. On the other hand, the presence of a sensor affects the cost of the display, and it makes sense to use this feature mainly in advanced MFPs with an abundance of additional functions.

The diagonal of the display installed in the MFP.

The larger the display, the more convenient it is to use, the better you can see the image on it. MFPs with a large display(from 7" and above) are especially convenient when you need to view various graphic materials on the screen — for example, photos for printing or scanned results. In addition, a large diagonal is highly desirable for touch screens (see "Display "). On the other hand, the larger the display, the more expensive it is and the more space it takes up, despite the fact that a small diagonal is enough for basic tasks and settings (this is already better than models without a display). Therefore, even in the most advanced models this indicator does not exceed 10.4", and in general, large screens are typical mainly for high-end MFPs with an abundance of additional features.

The maximum grammage that the MFP can print on. The grammage of the paper depends primarily on its thickness; thick paper is strong, but if it is thicker than allowed by MFP's manufacturer, the paper feeder simply cannot handle such sheets.

The maximum amount of received fax pages (see Built-in Fax) that the MFP can store in its own memory without being printed. This feature allows you, among other things, to output saved pages to a PC, thus saving paper, to receive faxes when there is no paper, and so on.
