Getting the message in /var/log/cups/error_log while doing a test page on printer on Fedora 10 - " client-error-document-format-not-supported: Unsupported format 'application/postscript'!"

Any help ???

Thanks.

Post the output of:
(Be sure to copy the expression exactly.)

[root@localhost ~]# grep '^#* *application/postscript' /etc/cups/mime.*

I just wanted to confirm you didn't have those entries commented out. Next, I would suggest editing cups.conf such that the following directive is in place:

LogLevel debug

Save that change and restart cupsd. Then try printing again, and review /var/log/cups/error_log again. It should give some more verbose chatter (and sometimes cups is intelligent enough to even offer a fix).

Confirmed that these entries have not been commented out. Before posting this issue, Changed LogLevel to Debug mode in cups.conf and provided the same output (error log) in the first post.
