After linux update of cupsd everything is printing out extremely slow

What settings can be changed in cupsd to make the printing faster. These are only label printers using the raw print queue option. Once I ran some typical Red Hat updates the printing slowed down tremendously.

Running http://localhost:631/ is quite the only reasonable option to adjust cups settings. You need to find out if the update has changed or removed any configuration settings set by some specific printer driver. Maybe add your printer(s) again from scratch via http://localhost:631/

None of the setting were changed actually I looked at the default cupsd.conf.default file which is the original config before the update and it is exactly the same as the cupsd.conf current file. I have a ticket open with REDHAT this is definitly related to the rhn update and I also went through the http://localhost:613 page but there are no rel performance settings. Im wondering if it has to do with the authentication setting each time a print job is generated.

Can you try backing out the update. Or more specifically back out the cupsd update if any were done?

OK so here is the absolute solution on this rollback. The question I had such a hard time getting an answer for is YES an RHEL5 Linux Update can be rolled back. First check your current packages under /var/log/rpmpkgs or type #rpm -qa | grep cups
Then using the yumdownload command get the version you need. The version I wanted was cups-1.2.4.El5, I typed in #yumdownloader cups-1.2.4.El5 this will automatically download the files to the current directory. Keep in mind there are lib files also so you will need to type #yumdownloader cups-libs-1.2.4.El5 as well to get these files, they are dependent on eachother. If yum is not working type
#yum yum-utils to add the program. Once you have all the needed files run the following command with all the filenames. This will roll back your version
#rpm -Uvh --oldpackage <filename> <filename> <filename>

This will not affect your cupsd.conf or printers.conf config.

Oh yeah then run
#service cups stop
#service cups start
