Hello!

We have identified the problem, and found a server-side work-around:

* Cups clients up to 1.5.2 uses Print-Job.
* Cups clients from 1.5.3 uses Create-Job + Send-Document
* The default authtentication ruls on the cups 1.4.1 server differs
  between Print-Job and Send-Document. Print-Job do not requre
  authentication but Send-Document do.
* After client upgrade to 1.5.3, Send-Document fails with
  authentication error, but you never get that error message on the
  client...

Our work-around is to disable authentication for Print-Job on the
server side.

However, I don't think a client upgrade should lead to this type of
problems, espesially not without an error message stating
authentication error in Send-Document.

Also, you don't expect a dot-upgrade, 1.5.2 to 1.5.3, to change
protocol usage in the client...

https://bugzilla.redhat.com/show_bug.cgi?id=827402 describes similar
problems.
