If there is one pixel of color the printers will usually treat it as a color print.

What format is the image you are going to print?

Try converting it to a PCX or other bi-color format to print. This will likely look ugly, but will let you see if your printer will indeed print black only.

Then try saving the image as a grayscale copy and see if this also prints OK.

hi

tiff grayscale negative scan from an epson scanner.

I've tried: grayscale, duotone, rgb, cymk, and that gave me the same result.

with a color reference pic i've got the same problem with gray region, they appears too cyan or green.

with color pics it's much easy to correct the color shift but with grayscale pics.....

thanks for your help

PS: with PCX i'got the same results.
