I can't print in color the ''color fill legend'' on a Sheet. Only in shades of gray.

Hi.
Can anybody help me with a problem I have?
I print an entire sheet in color except for the ''color fill legend'' which insist at, printing out only in shades of grey .
The same happens also when trying to print the ''visible window''.
Is there a regulation that I maybe didn't saw?
I made also a new project only with a few rooms and ''color fill legend'' and still is printed (the ''color fill legend'') in black and white when everything else (the areas) in color.
Thank you.

The problem was the long distance of the ''network'' printer.
I changed office and now at much near distance everything is fine.
Go figure!
