AP:printing of Checks and vouchers on same printer

[abbas9001]

Hello,
My Scenario is in AP payments are build,Formatted(Checks are printed on printer1),
Confirmed(vouchers are printed on printer2)
Now the requirement is to print checks and vouchers on the same printer
and for that I need to enhance the .rdf report so that checks and printed first and then vouchers related are printed, followed with checks and vouchers respectively
Concurrent program being submitted for printing of checks
and spawned program is being user for printing of vouchers
Early replies are appreciated.
Regards,
Abas
