How can I print on CD/DVD with a Epson PX700W printer?

[Jürgen Schöneberg]

Hello!
I just managed to install pipslite_1.4.0-3 and iscan_2.20.0-6.ltdl7 for my  
epson px700w  printer/scanner on ubuntu studio 9.04.

Printing on A4 paper and scanning to the PC works fine.

Question: Did somebody manage to print on a CD/DVD?

When I look in  in the menu  
System->Administration->Printer->Stylus-Photo-PX700W->Properties->Printer 
Options 
I can select different paper (A4, A6) and photo paper,
but it seems not to have a options for the CD printing.

Is there somebody who has experience with that (positive or negative)? 

Thanks
Jürgen
