Comment 3 for bug 43303

I am having the same problem and it's due to:

D [09/May/2006:17:14:53 -0600] print_job: request file type is application/octet-stream.
I [09/May/2006:17:14:53 -0600] Print-Job client-error-document-format-not-supported: Unsupported format 'application/octet-stream'!

I tried to open a bug report on this, bug #43145, but it got closed, and I have had no response trying to get it reopened.

Can you check your /var/log/cups/error_log and see if you are having the same problem? I have tried many, many things and no luck on this.
