OK, I built wx --without-gnomeprint and tried it with survex-aven (since
it's a package I maintain and know well).
The first problem is there's no print preview - when you build it, the
preview button is disabled if wxUSE_LIBGNOMEPRINT is defined (since
this avoids having print preview buttons on two consecutive dialogs).
This is essentially an assumption in the survex code that the wx it
was built against is configured the same way as the one it is run
with. That's arguably a bug, but I don't think you can easily
dynamically test for features in the wx library you get dynamically
The next problem is that the print options default to print just the
first page, though this isn't totally obvious (it shows as the pages
radio button selected (rather than all) and 1 to <blank> in the range.
The other issue I noticed is that you can now only print PostScript
rather than PDF, which is annoying - you can pretty much rely on
people having a PDF viewer but PostScript ones are rarer, and having
to convert with an external tool is annoying.
On the plus side, if I rebuild survex-aven then the built in preview
seems to work better than I remember.
So based on this single data point, disabling gnomeprint will cause at
least some issues with dependent packages of wx.

I'll definitely take a look at this.

Having gone through the packages involved, it seems realistic to me:
