I got excited when I saw your close - I thought for sure the open handle was causing the grief.
Added the error checking. Nothing.
Something is foobar here and I am not sure it is perl. Even from the command line...
cat foo.ps | /usr/bin/lp -o nobanner
prints the postscript code while...
/usr/bin/lp -o nobanner foo.ps
Prints the postscript document. So I really can't expect my perl script to work as written.
