We often see the word multifunction "printer" being used, but it is an understatement to call a multifunction printer a printer. Perhaps the more accurate word should be "copier", but that word is now widely used to mean a photocopying machine.
Here is why I think a multifunction printer should be called a copier instead. The function of a multifunction printer is to print, scan, copy, and (sometimes) fax. Printing is simply making a hard copy from a soft copy. Scanning is making a soft copy from a hard copy. Faxing is making a remote hard copy. It is all about copying, so why do we keep calling it a printer?
Perhaps not to confuse it with a photocopier by calling it a copier, how does multicopier sound to you?
