Changes to Qt Print Support

Qt 6 is a result of the conscious effort to make the framework more efficient and easy to use.

We try to maintain binary and source compatibility for all the public APIs in each release. But some changes were inevitable in an effort to make Qt a better framework.

In this topic we summarize those changes in Qt Print Support, and provide guidance to handle them.

General API consolidation

The various enums and types for page sizes, margins, and orientation have been consolidated. QPrinter APIs to set paper sizes and margins explicitly have been removed; use QPagedPaintDevice::setPageLayout(), QPagedPaintDevice::setPageSize(), QPagedPaintDevice::setPageOrientation(), and QPagedPaintDevice::setPageMargins() instead.
