I use the Dark Grey Office Theme, and I noticed that the Print Preview background/canvas has been changed to white, it only shows in MS Word but not the full suite. Does anyone know a permanent fix to this issue? However, I recently stumbled upon an accidental workaround. While viewing a document in Print Preview (for example, Document 1) -where the background/canvas appears white- if I open a second Word instance or (Document 1) and switch its Office Theme to any other then back to Dark Grey (confirming with OK each time), the Print Preview in Document 1 immediately adopts the correct Dark Grey Office Theme. Interestingly, if multiple documents are open in Print Preview, performing this theme‑switching process in just one of them updates the Print Preview theme for all the others, except for the document in which the theme change was actually performed. Unfortunately, the effect isn’t permanent. Switching from Print Preview back to the Home tab and then returning to Print Preview causes the background/canvas to revert to white again.
