Use the Redaction tool under Tools - Protection.

after printing the redaction document area shows black that's big problem it will consume maximum printer ink.How can overcome it?

Before applying the redaction right-click it and select Properties and you'll be able to change the fill color to something else.

Edit: And if you also tick the "Make Properties Default" box in that window any new redactions you create afterwards will have this fill color by default.
