The obvious advantage of an A3 printer compared to the laser is the initial cost. You can now purchase an entry level inkjet for under $60 if you shop around which is a huge difference to the $800+ you will need to find before even looking at a comparable color laser printer. This can be false economy though if you intend to use the printer for more than just occasional use on A3 sized paper. One of the reasons the big four companies can sell inkjet printers so cheaply is because they know the new owners will be requiring replacement ink cartridges on a regular basis and these replacements aren’t cheap. For an ink cartridge costing $30 you are effectively paying around $15K per gallon!
