the problem is resolved .
i went to http://localhost:631/
>> Manage printers>> set the Printer Options >> Printout mode [ normal Greyscale [ Black Cartridge] ]
After this, went to the Document and printed it .It Printed
Not sure if in there is an option in the Document itself where i can make the same selection as above.ie without using http://localhost:631/
. Pls let me know if any.
