How do you set the Epson R1800 to use only black ink or black inks when
printing a B&W image?

It is then very easy to define a virtual printer that uses
whatever density for each color that you set. It also includes
one selectable "Color Model" that is "greyscale".

Despite the difficulty in achieving a colour-cast free image with
printers lacking two or more neutral black inks, the R1800 usually does
quite a reasonable job on OEM papers using the software (darkroom print)
bundled with the printer, or using ICC profiles and printing from PS (or
QImage) with ICM off / PS or Qimage handling colour.
I still get a slight colour cast in light areas - most people don't
notice, but if I printed more monochrome, I'd trade the R1800 in on a K3
ink Epson, or an HP pigment printer - once they get over the teething
problems, and there's better OEM and third party media support.
