HP D5460 doesn't print CD on Linux 64Bit

[Busico Mirto Silvio]

I fillowed instructions at http://hplipopensource.com/node/196
I downloaded and installed HPLIP 3.9.10 -15.0 (Qt4) (sow I see all 5 cartridges)
but when I try to print a CD the printer wait some seconds and than says the CD tray is open (of course the CD support is in!): If I extract the CD support and close the CD tray, the printer prints on paper.
If I use M$ windows it prints fine over a CD.
I'm using Kubuntu 9.04 64Bit
What can I do?
