I'm not sure.

try the following ...

        clf
        surf (peaks)
        print -dpsc test.ps
        [status, output] = system ("lpr -l test.ps ; lpq")

If the que is empty, then I suggest you verify you can print from the command 
line.

I have limited experience with "lpr", but if you have questions please ask. If 
I can't help, someone else will be able to.
