Comment 4 for bug 276884

I've been looking at this. The fix Kyle suggested does help, but as Tim pointed out, doesn't solve the root problem. You still won't be able to print with such a printer (or at least, I couldn't).

The root problem is that the Python lower() method on strings is locale-dependent. When _expand_flags tries to assign attributes, it converts uppercase strings to lowercase attributes. In the Turkish locale, the letter I (eye) is not lowercased, resulting in attributes like 'rejectIng'. This causes problems all over the place.

Background on this can be seen in this thread: http://mail.python.org/pipermail/python-list/2008-January/644769.html and in the Unicode spec, section 5.18.

You can test that this crazy situation is true by the following commands:

$ LANG=en_US.UTF-8 python -c "import locale; locale.setlocale(locale.LC_ALL, ''); print 'TURKISH'.lower()"
turkish
$ LANG=tr_TR.UTF-8 python -c "import locale; locale.setlocale(locale.LC_ALL, ''); print 'TURKISH'.lower()"
turkIsh

What is really wanted is a non-locale-dependent 'lower' function here, which Python apparently does not provide. It's simple to write, but I'm surprised it's not already there.

I've made that change in the code and I *still* can't get it to print, but at least I'm not seeing exceptions. I'm still investigating, but it may be more lower()/upper() goofiness.
