Hi!

I'm really not sure what you are trying to do exactly, but I have been using
Tookit.getPrintJob(Frame, string , properties); method for printing without
any problem.

Hope I have answered your question.

Oh BTW, we have written a cool JavaBean called PrintLet,  for printing.
Download it at www.palmsoftware.com. It might help you.
