Java3D 1.2 printing problem!

[yangyuexiang]

Hi, Everyone

I am glad to know the availability of Java3D 1.2.

But who can tell me the difference between V1.2 and V1.1.3. Thanks a lot.

Just now, I replace the v1.1.3 with v1.2. My printUtility (print Canvas3D)
doesnot work.
I attatched my PrintableCanvas3D.java file here.

Thanks very much!
