PageSettings Continue to Modify Unexpectedly

Question

It seems that you can save the PrinterSettings settings file as well as PageSettings, they are Serializable, etc. Fine! Everything went fine until I tried to save my pages and fields. Each time I change the fields, save the settings, and then reload them back to PageSetupDialog.PageSettings - they have been changed. Does anyone know why this happened? Is this something that the driver or Windows does? Its freaky, see below:

Here I show the dialog:

PageSetupDialog psd = new PageSetupDialog();
psd.PageSettings = MySettings.Default.pageSettings;

    if (psd.ShowDialog() == DialogResult.OK)

I manually change the values ​​to 5.

Then I save the changes:

MySettings.Default.pageSettings = psd.PageSettings;

When I reload the dialog and load the settings from the settings file, the values ​​have changed to 2 !?
