Maybe just a step sideways: It actually should support printing, GtkTextView is the normal control for handling text documents in Gtk so GtkPrintOperation should work. Plus https://docs.gtk.org/gtk3/property.PrintOperation.export-filename.html exports to PDF. That's still true for Gtk4.

So that leaves charts, which we'd have to draw on a cairo (Gtk3) or OpenGL (Gtk4) canvas. Qt has https://doc.qt.io/qt-5/qtcharts-index.html but web searches turn up only https://gitlab.gnome.org/GNOME/goffice/-/tree/master/goffice/graph?ref_type=heads a fork of which we gleefully excised a few years ago. That would be a step or two backwards but I guess it would be preferable to writing our own chart library. The good news is that it is being maintained, though at 2-3 commits/year I wouldn't say it's actively maintained. It's not likely to migrate to Gtk4 any time soon.
