This is an issue with the CUPS package. This gets me almost every time there is an update to cups. When running etc-update there is a great temptation to think "mime.convs,mime.types should be safe to update". However, the default setting is to comment out the "raw" filter at the end of the file, which breaks windows clients "relatively" silently. Please could we have the raw filter "on" by default .. it will save many people lots of time and pain .. (in mime.types and mime.convs, just remove the "#"s) Thanks.. Reproducible: Always Steps to Reproduce: 1. run emerge -DUv cups (assuming new version) 2. run etc-update and update mime.types and mine.convs 3. listen to windows users scream Actual Results: Printing fails - silently. Expected Results: Printed The only tell-tale is /var/log/cups/error_log; E [24/Jun/2004:09:55:54 +0100] print_job: Unsupported format 'application/octet-stream'! I [24/Jun/2004:09:55:54 +0100] Hint: Do you have the raw file printing rules enabled? Sounds easy, but my first reaction is always to try debugging SAMBA first ..
enabled by default in cups-1.1.21_rc1 :)
