The way you've generated this patch looks pretty strange.

You have to add the checks existing in PageSetupDlgA to PageSetupDlgW instead.

Also, in order to increase the probability of your patches to be included
should either point to existing bug that each of your patches fix, or/and
add a test case which doesn't pass without your patch and does with it.

Just a too old patch, partially updated by script.

Instead or also?
I guess, this check is needed in this place in any way.

I do not know  a way to check print dialogs without installed printer drivers 
in the system/wine.

Looking at the file dates that doesn't sound plausibly. The patches
are supposed not just to be applied, but also tested with current
git sources.

No.

That's a relatively rare case which is simply to avoid. Have a look at
the existing tests how they test printing functionality. In any case
having a bug report or posting a backtrace (you are trying to fix a crash,
right?) would help.
