Here is a patch for the proposed change. https://gerrit.libreoffice.org/c/core/+/88212
For the record, until LO 3.6 this was the case. Only since 4.0 is the button a simple OK.
(In reply to Gabor Kelemen from comment #1) > Only since 4.0 is the button a simple OK. Interesting. Temporally consistent with first entry in git history for printdialog.ui: # 87b5cdd5 10-Sep-2012 convert writer, draw, impress, calc and starmath printer dialogs to new-style widget layout mostly described in .ui format which suggests that "print" became "OK" for an unintended "generic" reason.
Well, I don't see a reason why it shouldn't be "Print".
