fullPage means the print engine shouldn't add any margins, the application will take care of that. That's already what happens on Linux and Mac, but the Windows print engine was offset-ting everything to the bottom right by the value of the margins, erroneously. As noted in QTBUG-95927, the workaround for this bug was to call printer.setPageMargins(QMargins(0,0,0,0)); when using printer.setFullPage(true), and this fix is compatible with that workaround, existing apps won't be broken. [ChangeLog][QtPrintSupport][Windows] setFullPage(true) now behaves as expected, i.e. the QPrinter margins are ignored and the drawing's (0, 0) is the topleft corner of the page. This is what setFullPage(true) is documented to do, and how it was already working on other operating systems. If this causes regressions in your application, consider removing the call to setFullPage(true) so that the painting honors the margins again.
