When deciding on a new wide format printer, it is important to know your TCO - Total Cost of Operation. So, you need to have a true idea of what it cost per page or per square foot to operate the unit.
Obviously, costs will fluctuate greatly depending on your printing application. CAD and General Purpose Printing will have much different metrics than graphics or photos. See the estimated cost per square foot for many Canon imagePROGRAF printers so you can make a better education decision.
