The R1800 is built like a tank, Epson have paid a great deal of attention to detail. I like the way the front paper tray is sprung loaded, just press the front to open and it glides up into position.
The R1800 uses the same UltraChrome ink set as the R800, in fact the cartridges are the same. I would have expected larger cartridges for an A3 printer. If the inks perform as well on this printer as they have on the R800 then I think we will be in for a treat, I will hold back from saying more until I have fully tested the printer.
