I'd vote for Laser for infrequent B&W printing. For color printing, Inkjet all the way as color lasers will kill you on toner costs.
Those complaining about ink costs - STOP BUYING THE CONSUMER PRINTERS! It's that simple. Pay a little more for the business class printers and your ink costs will go down dramatically. I've got an OfficeJet Pro 8500a and the inks are under $40 each and last for about 1k pages and "cleanings" are kept to a minimum. We go through a set a year if that. Certainly less than our previous color laser and not obnoxious at all.
