I'm guessing that you turned off the normal toolbars? If so - create a new toolbar just for the print function, & have it set to prompt user's for their printer.
A simple function I use is:
Public Function PrintOption()
On Error GoTo PrintOption_Err:
RunCommand acCmdPrint
PrintOption_Err:
Exit Function
End Function
Then I assign that function to a macro, & then assign the macro to the toolbar button. Kind of the long way around, maybe, but it works!
Hope this helps.
