These are all debugging messages and do not represent errors or anything to be concerned about.

One or more jobs were updated and need to be written to disk.

One or more subscriptions were updated and need to be written to disk.

The scheduler is busy doing something and needs to write files to disk.  This is used on Mac OS X to tell the OS whether cupsd can be terminated safely with kill -9 (for fast shutdown/sleep).

The print job was submitted without specifying a file type, and so cupsd is determining the type from the contents of the file.
