Print speed
The print speed provided by the plotter.
Such devices are intended for large-format material, so this parameter is usually indicated as m² per hour. Keep in mind that the spec usually give the maximum print speed, which is achieved at a reduced resolution and overall quality; in standard mode, the plotter may work noticeably slower. So when choosing for this parameter, it is worth taking a certain margin. On the other hand, according to the values indicated in the specs, it is quite possible to evaluate different models and compare them with each other: the difference in the claimed performance, usually, will proportionally correspond to the difference in the actual speed of work.
As for specific values, speed
up to 20 m²/h for modern plotters is considered low,
21 – 50 m²/h — medium, and in the most powerful and performant equipment this value can
exceed 50 m²/h.
Sheet printing
Ability to use the plotter to print on separate sheets of paper. Roll media is widely used in large format printing and some devices may not be able to handle other options. Therefore, the possibility
of sheet printing, usually, is separately indicated in the specs. At the same time, many models allow the use of larger sheets than provided by the supported paper format (see above) — the main thing is that the sheet fits into the device in width.
Media width (min)
The smallest width of paper or other media that the plotter can handle. Such devices, by definition, are designed for large-format printing and are poorly suited for small media; therefore, if you plan to frequently print on sizes smaller than standard (see "Paper Size"), you should pay attention to this parameter and make sure that the selected plotter can work with all the necessary materials.
Number of cartridges
The number of individual cartridges the plotter needs to operate.
Each cartridge is responsible for its base colour used in printing. Monochrome plotters (see "Output Type"), by definition, use only one cartridge, for black colour and for such devices this parameter is usually not specified at all. But in colour printing, where all available shades are obtained by mixing basic colours, the number of such colours (and, accordingly, cartridges) can be different.
The most modest of modern colour plotters are designed to work with
4 or 5 cartridges. The first option corresponds to the CMYK colour scheme with 4 basic colours — this is the minimum required for full colour printing. In turn, 5 cartridges usually mean a CMYK colour scheme, supplemented by a separate supply of black ink for monochrome images — this allows you not to waste consumables for such images that may be needed for colour prints, and also to print monochrome even with empty colour cartridges, and vice versa.
In general, these sets of basic colours are inexpensive, while they are able to provide fairly good quality prints; so plotters for 4 – 5 cartridges are very popular nowadays. However, the use of additional basic colours can significantly increase the quality of the image, primarily the reliability of colour reproduction. Thereby, advanced plotters can provide a larger number of cartridges —
6 – 10, and s
...ometimes more. Such devices are quite expensive and difficult to maintain, but they are indispensable for printing materials with high requirements of colour quality.Cartridge model

Power consumption
Rated power consumption of the plotter. Usually specified by the maximum value — for the print mode, when the device requires the most power.
The heavier and more performant the device, the higher its power consumption in general. At the same time, models that are similar in performance may differ in this indicator. And here it is worth proceeding from the fact that a more energy-efficient unit usually costs more, but with intensive use, this difference can quickly pay off due to energy savings.
In addition, the power consumption may be necessary for special electrical calculations — for example, determining the necessary parameters of a voltage stabilizer, a backup generator, etc.
Dimensions with stand (WxDxH)
The overall dimensions of the floor plotter (see “Placement”), including the stand, in other words, the dimensions of the device in the operative condition (in addition to the stand itself, other equipment, such as trays for printed materials, is taken into account here). This indicator is worth evaluating how much space is needed to install such a plotter.
Weight
The total weight of the plotter is usually listed without ink and paper. You should pay attention to this parameter foremost when choosing desktop models (see "Placement"): modern plotters are quite massive, which puts forward corresponding requirements for stands for them.
