Hi, I meet the same problem: blank page when printing or printing preview.
By searching on internet, I have found this: https://github.com/qutebrowser/qutebrowser/issues/4599 Based on that, I have compared source codes of pdfium_document_wrapper_qt between from versions 5.11 (https://github.com/qt/qtwebengine/blob/5.11/src/ core/printing/pdfium_document_wrapper_qt.cpp) and 5.12 (https://github.com/qt/ qtwebengine/blob/5.12/src/core/printing/pdfium_document_wrapper_qt.cpp). And there are some modifications mainly in the function "QImage createImage". Could this be the cause ? Maybe can somebody do the test. Mathieu
