8 \brief General API consolidation.
9
10 Qt 6 is a result of the conscious effort to make the framework more
11 efficient and easy to use.
12
13 We try to maintain binary and source compatibility for all the public
14 APIs in each release. But some changes were inevitable in an effort to
15 make Qt a better framework.
16
17 In this topic we summarize those changes in Qt Print Support, and provide
18 guidance to handle them.

20 \section1 General API consolidation
21
22 The various enums and types for \l{QPageSize}{page sizes},
23 margins, and orientation have been consolidated. QPrinter APIs to set
24 paper sizes and margins explicitly have been removed; use
25 QPagedPaintDevice::setPageLayout(), QPagedPaintDevice::setPageSize(),
26 QPagedPaintDevice::setPageOrientation(), and
27 QPagedPaintDevice::setPageMargins() instead.
