I assume that your problem happens with the IPP-based print queue
clp315wsplc (a Samsung CLP-310 or CLP-315).

Do you have one printer where the two print queues are pointing at or do
you have 2 printers? Which model(s) exactly? Which drivers are you using
with it/them and how well they are working?

Your problem is a buggy IPP implementation in your Samsung printer. It
does not prevent you from printing but generates the error messages. To
avoid these errors the simplest solution is to not use IPP as network
connection type. Instead, use AppSocket/JetDirect or LPD. When you use
the "Add printer" wizard of system-config-printer, on the first page you
see a list of detected printers with your Samsung(s) under the network
printers. When selecting your printer on the right at the bottom a
"Connections" list will appear. You get IPP, LPD, JetDirect/AppSocket,
and perhaps more. Best is to select something like "JetDirect/AppSocket
via DNS-SD". Note tha DNS-SD assures that your printer stays connected
to your computer if the router assigns another IP address to it.

We cannot do anything against the buggy IPP implementation in your
printer, therefore I am closing this bug now, but please tell us anyway
what you have found out.

  Invalid

Bug description:
  These status messages are shown in printer properties:

  Printing still works, which is good, but I can't do anything to the red error 
signs in Printing dialog.
