Re: piping to lp is broken after perl upgrade

[moritz]

You should check if open was successful, and also if close was:

open my $output, '|-', $PRINT_CMD
    or die "Can't open pipe to $PRINT_CMD: $!";
print $output $prolog;
...
close $output or warn "Error while closing pipe to $PRINT_CMD: $!";

Maybe that'll give you some clue about what's wrong.

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.
