With all things considered, I break it down to three distinct categories. Ink jets, for professional photos and business formal prints are the best and can run from $50. to $300. USD. Next comes the laset types, where a laser draws in a photosensitive drum, picks up toner and deposits it on the paper and then fused to the page with heat. These are excellent for black only and high speed orientated for network printing. Color on a laser jet is a complicated process of getting four different colors toners (black, cyan, magenta and yellow) onto the page. LED'd being used to do the drawing instead of lasers has advanced the process somewhat but remains a delicate balance with particle charges and fusing devices. Many users opt for an all in one device and this can complicate things even more. From a service point of view, the laser machines can have several methods of replacing toner and photo drums together as a single device or as seperate assemblies. These can also create user generated trouble. Replacing ink cartridges and a regular cleaning internals will yield exceptional lifetimes and refilling cartridges from bulk sources will help to keep the cost per page down. Laser and LED types will seldom need more than a little cleaning each week to keep trouble free. Laser/LED internals are susceptable to dirty conditions as any bridges across insulated parts can cause blurry, ghostly and streaked printouts. A simple paper jam can cause all manner of problems when sheets get pulled out or torn. Simple conclusion, Laset for black only, high volume, network type devices and inkjets for color. All number of options with built in network, WIFI, BlueTooth and other wireless links can support an office with all manner of inputs from BlackBerries to a laptop/desktop. Consider all the needs and options against the budjet and I would like the color laser unit but that would hang totally on the photo reproduction. In an AIO unit, a color copy will reveal acceptablity.
