Key features:-
A type of printing technology that uses small dots of ink to create images. Printing in color or black and white is available.
All-in-ones require printer memory to store and process information while printing. Measured in megabytes (MB), the more memory the device has the faster it will print.

A type of printing technology that uses toner to create images. Printing in black and white is available. (Color laser printing is available, but is prohibitively expensive.)
There is a reasonably close correlation between the low price of some machines and their high running costs that means that some machines are not the bargains they might at first seem.
A higher-priced machine with a lower running cost in terms of ink cartridges is likely to pay for itself pretty quickly
A measure of the pages per minute (ppm) a device can fax, copy, or print. For a single multifunction office machine, each speed measurement could be different.

Better equipped all-in-ones will be able to print on different sizes and types of including glossy for photos. They will also be able to output overhead transparencies, labels and CDs or DVDs.
The price of replacement ink cartridges will have a significant effect on running costs for an inkjet-based all-in-one. The high prices have seen a small industry spring up in the refill market with 50 per cent savings to be made. However, continual refilling may eventually have an effect on the printer and may cause some conflict with manufacturer's warranties. Avoid colour cartridges that combine three colours - when one runs out you have to throw away what remains in the other two sections.
