If the smaller printers could use this size, it would save a lot of money. It would also cut down the panic dashes to Computer World when you run out of ink half way through a big job. The printheads are separate from the ink cartridges, meaning their life is extended. This, however, doubles the number of consumables needed. This isn't as bad as the color lasers, but is more complicated than a home ink-jet.
Speed is a big issue when it comes to office printing.
But unfortunately, this printer's speed is not easily measured. Laser printers print at engine speed, so once the image is processed, pages will spit out at a predictable rate. HP claims 15 pages per minute is possible, and indeed, the 2250tn is more than capable of this. As long, of course, as the image is small. In its fastest, lowest-quality mode, the 2250tn can quickly print clear and useable pages.
