Printing by a second printer

[Mota]

Hello;
I have 2 reports,named OrdersRpt and PricesRpt,and want to print them by two
separate printers connected to my system.I use this code to print them by
default printer:

Private Sub cmdPrint_Click
DoCmd.OpenReport "OrdersRpt"
DoEvents
DoCmd.OpenReport "PricesRpt"
MsgBox "Two reports been printed
Successfully",VbOkOnly+VbInformation,"Printing Reports"
End Sub

The prints are followingly,but since paper sizes are not equal i preffer to
send them to two separate printers and print them synchronizingly.How can i
do this?What to add to my code and where?any suggestion?
Thank you so much in advance.
