After upgrading from 9.04 to 9.10 I got the same error with any printer that was working previous to the upgrade.
I proceeded to run the apport-collect to provide information about the error and enabled the debugging of cups. Find attached a copy of my error_log file. After some googling, I found a possible reason why cups will give that error message is when it's unable to handle the mime type of the file. On my case, I've been trying to print postscript files (application/postscript) which have an entry on my /etc/cups/mime.*
