The Print dialog's Print Preset list loads [Default] or a saved preset
(reading [Custom] once the settings differ) and Save Preset... names the
settings as a preset. Edit > Print Presets... lists [Default] (generated,
protected) and the saved presets with how they differ from it; New... and
Edit... open the preset editor (the Print dialog's sections), Delete,
Import... and Export... use .vcprintpresets files, which File > Open also
imports. Commands print.presets.list/save/delete/import/export; the presets
live in Prefs.print_presets and persist with the preferences.
The open-dialog filter count test counts the new Print presets filter.
