Kai,

what I could deduce immediately from your files is that the LPD service on 
your Windows box obviously does not conform to the LPD protocol as described
by the RFC 1179 (that is the one cups-lpd is designed after), whereas the 
mac side behaves correctly (as you stated earlier).

What kind of LPD software do you use on your Windows box?
