It's a grayscale file. As I said, I don't think the printer is using only black -- it is combining all its colors to produce or emulate a gray. I was able to force it by setting the printer to print on black and white (via the printer driver) but the output was poor.
The Epson 1400 uses six inks:
Black, Cyan, Magenta, Yellow, Light Cyan, and Light Magenta
Originally posted by graphicgr8s When you open the file and look at the mode does it say "Grayscale" ? Or did you just desaturate the color. "Grayscale" forces the printer (most anyway) to only run black in. Gray, any shade of any of the four colors actually, is only an illusion. The printer either prints 100% of the color or prints 0% of the color. There is no middle ground. What varies is the size of the dot.
Just desaturating the image causes the printer to try to make the grays using all four colors. One other thought. Is it a CMYK printer or a MYK printer. My dell only prints 3 color. No black so it's always a color build.
