Hello Serando,

I managed to rebuild your configuration (mostly, without the real printer, of course), and
the printout of the loschcups.txt was the same when printed via tea4cups or directly.
But, as I some time ago replaced the textto… filters by my own homegrown filter(s), I cannot guarantee
if my results are identical with yours.
Are you sure you used the very same print queue in both cases?
