Print Colored Rows In A Datagridview

CrankyMero asked:

Hello Everyone

So I have 2 datagridviews that compare information between them and if it does match it colors the rows in green and after its done all the white spaces colors the rows in RED, so the main thing is that i dont know how to print only the RED rows.

This is the method that i use to print normally

PRINT BUTTON

Dim dlg As New PrintPreviewDialog()
    
            dlg.Document = PrintDocument2
    
            dlg.ShowDialog()
    
            Dim psDlg As New PageSetupDialog

DRAW FOOTER

Private Sub DrawFooter(ByVal e As System.Drawing.Printing.PrintPageEventArgs, ByVal RowsPerPage As Int32)
    
            Dim sPageNo As String = nPageNo.ToString + " of " + Math.Ceiling(Emp_attDataGridView.Rows.Count / RowsPerPage).ToString
    
            ' Right Align - User Name
            e.Graphics.DrawString(sUserName, Emp_attDataGridView.Font, Brushes.Black, e.MarginBounds.Left + (e.MarginBounds.Width - e.Graphics.MeasureString(sPageNo, Emp_attDataGridView.Font, e.MarginBounds.Width).Width), e.MarginBounds.Top + e.MarginBounds.Height + 7)
    
            ' Left Align - Date/Time
            e.Graphics.DrawString(Now.ToLongDateString + " " + Now.ToShortTimeString, Emp_attDataGridView.Font, Brushes.Black, e.MarginBounds.Left, e.MarginBounds.Top + e.MarginBounds.Height + 7)
    
            ' Center  - Page No. Info
            e.Graphics.DrawString(sPageNo, Emp_attDataGridView.Font, Brushes.Black, e.MarginBounds.Left + (e.MarginBounds.Width - e.Graphics.MeasureString(sPageNo, Emp_attDataGridView.Font, e.MarginBounds.Width).Width) / 2, e.MarginBounds.Top + e.MarginBounds.Height + 31)
