The problem here is that printer-driver-postscript-hp provides 3 identical PPD with the same *NickName: "HP Color LaserJet 2605 Postscript (recommended)" while it should differentiate between 2605/2605dn/2605dtn.
In cups webinterface 3 identical PPD entries are shown while system-config-printer only shows one under 2605 and since the Foomatic/Postscript 2605dn is more specific this one is (incorrectly) matched.
