The time from the document/image is sent for copying till the copier is ready and the first (black and white) page is printed. The faster the first page out, the better.

The maximum number of dots of ink applied to paper while printing. Specified as vertical/horizontal (for example, 4800x1200) or as the number of dots per inch (for example, 1200 dpi).

Ability to automatically make a copy of both sides of the sheet. There is no need to manually turn the sheet. Often used to save paper (for printing documents of little importance) or to make booklets, etc.

The maximum number of pages that can be loaded to the paper supply tray at one time.

Standard copiers are designed to print only on light grammage plain paper. The thicker the paper, the more difficult it is to handle with it. Too low paper grammage leads to sheets jamming. Therefore, the greater the difference between the minimum and maximum paper grammage used by the copier, the better.

The maximum number of pages that the printer's ink can copy. The value is rather conditional, in fact the deviations from this value are very large (up or down).

Measured in decibels. Knowing the level of noise performed by the copier while printing, you can guess whether it will be convenient to use it indoors (for example, a common office room).
