There are currently five models that are part of the EcoTank line: two consumer-level printers (the $380 Expression ET-2500 and $400 Expression ET-2550 ), two business-level all-in-ones (the $430 WorkForce ET-4500 and $500 WorkForce ET-4550 ), and the $1,200 heavy-duty WorkForce Pro WF-R4640 . On the whole, these printers tend to cost more than their traditional equivalents -- for example, an inkjet all-in-one such as the HP Officejet Pro 8620 retails for about $150 rather than the $430 or $500 that you'll pay for one of the EcoTank printers.
While the majority of inkjet printers can be found mainly in a home or a home office, inkjet technology is showing up in more and more business-oriented models meant for heavier-duty printing, including high-end ones that can rival laser printers in speed. They tend to do this by using print heads that run the full width of a page. Although their maximum monthly duty cycles still fall short of heavy-duty lasers, higher-end inkjets are still capable of handling the printing needs (and, in the case of MFPs, copying, scanning, and faxing as well) of many workgroups and small offices.
