Max. roll diameter
The largest roll diameter that can be installed in a plotter with roll printing (see above). This parameter is useful primarily for the selection of media: the material of the same width can be produced in rolls of different diameters.
Number of rolls
The number of rolls that can be installed in a plotter that can print from such media at one time (see above).
Most often, such models are made for one carrier, however, there are also more advanced units — for
2 or more rolls(in some cases this number reaches 4). The meaning of this functionality is that you can simultaneously use media of different sizes (for example, A1 and A2) or/and types (for example, glossy and matte paper) while printing. Of course, you can only print on one material at a time; however, the presence of multiple rolls allows you to switch between them simply through the settings of the plotter, without fiddling with changing media.
Cartridge model
Models of cartridges used in the plotter. With this info, you can easily find original consumables for the device.
Built-in memory
The amount of built-in memory provided in the design of the plotter.
Such memory is used to store various service data: print tasks, settings profiles, etc. Due to this, the plotter becomes more "independent": for example, many models allow you to continue printing even when the master PC is turned off.
We emphasize that in this case we are talking about solid-state flash memory, which is used mainly for "operational" service information. The capacity of such memory is relatively low, it is measured in megabytes; but in addition to it, the design may include a larger storage capacity — usually a traditional hard drive. For more information about it, see "Drive Capacity".
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.
