This is a know issue, I stumbuled upon it this week too. I already spent several hours trying to found the origin of that issue. When debbuging is activated, from the logs (like the attached one), I can see that cups' max connection is reached, then after a timeout expire the page is returned. But there is also other errors, such as broken pipes, non extsting files share/doc/cups/admin/conf/cupsd.conf. I don't know where to begin. At the moment testing modification to the cups package to be used in the service take a lot of time since the cups package is a dependency for a lot of packages (~3000), if someone know how to speed this up I'm interesseted.
