Hi, I'm printing from an SUSE 11.1 (cups 1.3.9) onto an SUSE 10.3 (cups 1.2.12) and get the a.m. error message. Web search with big brother brought that in /etc/cups/mime.types the line application/octet-stream Should be uncommented. In fact this is the case, but I still get the error. Any recommendation? Thanks Axel
