Description
qtbase/tests/auto/printsupport/kernel/qprinter/qprinter.pro is marked as an insignificant_test, meaning that test resultss are discarded and do not help the CI system to block regressions.
Recent test runs seem to show the test passing on linux, being skipped on Windows and failing in several different ways on Mac.

In addition to the above failures, it is not clear to me whether the CI system is properly setup for this tests – I doubt that any of the CI machines have any printers configured, which might cause portions of the test to be skipped, and I have seen at least one code path in QPrinter that failed only if there was at least one printer configured.
It may be worth investigating whether some kind of virtual printer device can be used to make this test more reliable and more useful for CI, particularly if the test was able to control how many printers are available so that tests couldbe rerun with 0, 1, 2, and many printers.
