will it make a color copy directly from the printer ?
that makes it an issue with the computer
there should be a check box for "gray scale" when you go to print
make sure that is NOT checked
it might also be in the printer driver if you go to devices and printers and right click on the printer and select PRINTER PROPERTIES
there might also be an issue with it using a gray scale color map though its a lot less likely
if it can copy in color than it can print in color.
the copy function scans the image and then prints it. there is no real difference between that and the computer sending the image
what that says is the problem is on the computer side of it.
is it printing a picture completely but in gray or is it just leaving blank space wherever there would be color
that would seem to be the issue
and again there should be a box somewhere in the print options or preferences that tells it to print gray scale.
it might have got auto set if it was low on color toner but you should still be able to find it and change it
i have an offer up to log in remotely to do it for you. if you want to accept that i can do it this afternoon
this is what it looks like in acrobat reader. its a different printer but it has the same options
I am sorry that you feel that way. But unless you can find that option for gray scale and tell me that it is not set to on than i have to think that is the most likely cause
if you cant find the option than i would be happy to log in and find it for you.
