default printer confirm

I have built a mail merge program that prints to my local printer. I have a little problem in that it always asks to confirm the printer. Must I change my printer defaults on my system, or can within my vb program simply say print with default printer confirm yes or something like that?

Re: default printer confirm

'that is changing default printer only for current application
but it won't change default printer windows wide

Code:

Private Function SelectPrinter(ByVal printer_name As String) As Boolean Dim i As Integer SelectPrinter = True For i = 0 To Printers.Count - 1 If Printers(i).DeviceName = printer_name Then Set Printer = Printers(i) SelectPrinter = False Exit For End If Next i End Function Private Sub Form_Load() Dim i As Integer cboPrinter.Clear For i = 0 To Printers.Count - 1 cboPrinter.AddItem Printers(i).DeviceName Next i End Sub 'choose in combo printer_name

Re: default printer confirm

Thank you for you intensive piece of code, I think That I may not have explained my problem good enought. As with every VB problem I guess it's understanding the problem that is half of the solution.
When I do my mail merge, My word application in .visible = false so all is done in the background and nothing appears on the screen.

The mail merge is sucessfull as I can out put it two ways
.Destination = wdSendToDocument
or
.Destination = wdSendToPrinter

Once I execute my merge,

.Execute Pause:=True

I get my output either sent to a new word documents
or in case two to my printer.
It is at this point I am having a problem
I continually get a window poping up to select my printer(which is already selected as my default printer) I must press the OK button to continue printing.
I want to skip this window and the OK button.
Is there not a "confirm=false" or some thing like when you save
" wdApp.ActiveDocument.Close (False) "
How about
wdapp.activedocument.printout (false)
there must be something simple.

Re: default printer confirm

I understand how is possible to set the default printer , but i need to set only the printer for my application.
I try to describe my problem: I have two datareport in vb6 application.
The first will be printed with the default printer but i must to print the second on another printer so i can't change the default printer of the pc .
thank u
