Why are you using assert() and kill the test? 
Is skip not enough?

You added a ok() for "dm =! NULL", but "dm" is accessed always and will
crash the test.

Same here for "dn".

You introduced the same bug, as you did in in your previous Patch!
(test_DocumentProperties)

dm->dmDeviceName is limited to CCHDEVICENAME

info.c:2093:fields 7b13
info.c:2095: Test succeeded inside todo block: fields 7b13 != dmFields
7b13

I get the same "succeeded inside todo" for all printers

Why is it so difficult to add the tests in alphabetic order?

This Patch dump a lot of unneeded data.
Please remove the traces (or dump the data only in interactive mode).

Thanks

Skip is supposed to skip tests for optional functionality that doesn't
present on some systems, that's not the case here.

That's the point of the test. dm and dn must not be NULL in all cases.

I don't see a problem here.

I have only 1 configured printer here: "Wine Postscript Driver", and the test
fails for me.

Some tests may depend on the results of other tests, or cause side effects,
so it's always good to add the tests at the end of the sequence to not cause
any possible problem. Feel free to send a patch and re-arrange the tests.

The traces are supposed to help understanding what's wrong with the test when
somebody looks at the test results at test.winehq.org and trys to figure out
how to fix a failing test.

The test exercises the functionality of winspool, but does that with the help
of PrintDlgA to avoid code duplication. The test doesn't add a hard dependency
on comdlg32.dll, so I don't see a problem.

Thanks for the review.

You introduced the same bug, as you did in in your previous Patch for
"winspool.drv", which was commited on 15. April 2006 
(test_DocumentProperties and test_DEVMODE)

Example failure for "Microsoft Office Document Image Writer":
http://test.winehq.org/data/200605051000/xp_RAYEN/winspool.drv:info.txt

More Examples for failing tests:

I use wineps.drv (WINEPS Printer using CUPS), but the drivers have the
same name as the cups-printer (patch from Huw a while ago).
My current cups-Printers are "cups-pdf" and 2 Parallel-Printers.

In this case, the test is broken and need to be fixed
(similar to the side-effects, that Paul fixed for advapi32)

You are able to fix it: Please fix it.

Dump additional data, when a test failed is ok, 
but in your Patch, the data is always dumped.

msi/tests use DeleteFile, but you would never add tests for DeleteFile
in the testsuite for msi.

Please add the tests related to PrintDlgA in
dlls/comdlg32/tests/printdlg.c

Thanks
