OK, thanks. So please go ahead with the fixes.

And I am also grateful if you do the maintenance of your code when it is 
in cups-filters as I do not know much about Braille embossers and also 
do not have such a device available to me.

How are Braille embossers connected and how do they appear for the 
computer? Do they work with the standard usb/parallel/socket/ipp 
backends of CUPS?
