As and pointed out, changing the parent form’s button state from the child is a perfectly valid quick fix (and confirmed it worked). A few clarifications and safer patterns make the approach more robust across VB6, VB.NET and Access apps.

Keep the parent responsible for its UI state (don’t directly manipulate another form’s private controls). Example: expose a small public method on the MDI parent that encapsulates the change, then call that from the child. This avoids depending on a control name and keeps compile-time checks clear.

' Parent form (MainForm)
Public Sub SetPrintButtonState(enabled As Boolean)
    cmdPrint.Enabled = enabled
End Sub

' Child form
Dim parentForm = TryCast(Me.MdiParent, MainForm)
If parentForm IsNot Nothing Then
    parentForm.SetPrintButtonState(False)
End If

For looser coupling, raise an event on the child and have the parent handle it (AddHandler / RaiseEvent). This is useful when multiple parents or presenters might host the same child form.

Access-specific note: from an Access form the typical syntax is different — reference the parent form via the Forms collection (for example, Forms("MainForm").Controls("cmdPrint").Enabled = False) or expose a public routine in a standard module/form and call that.

Troubleshooting tips: ensure the parent control is accessible (public or wrapped by a public method), cast Me.MdiParent to the actual parent type in VB.NET, and remember a modal dialog (ShowDialog) already blocks parent interaction so manual disabling is unnecessary. Avoid hard-coded control access from children to reduce maintenance issues.
