To Print 'n' number of copies in NAV 2016

Hi,
At present we print invoice having 3 carbon copy on the same invoice. Now we wants when any user gives print command, the printer should automatically print 4 copies of invoice .
On every invoice a line should be printed i.e. "ORIGINAL FOR BUYER" on first page, "DUPLICATE FOR TRANSPORT" on next page, "TRIPLICATE FOR ASSESSEE" ON 3rd page, "EXTRA COPY" on 4th page.

Please help.


Thanks in advance.
