Alternative idiom (not better, necessarily, just alternative):

BufferedReader source = new BufferedReader( New InputStreamReader(
p.getInputStream() ));

String line;

while ((line = br.readLine()) != null) {
System.out.println(line);
}

You can contain the scope of 'line' through a 'for' loop:

  for ( String line; (line = source.readLine()) != null; )
  {
   sink.println( line );
  }

or even

  for ( String line;
        (line = source.readLine()) != null;
        sink.println( line ) )
  {
  }

I would use a PDF JAR to print but the free ones like itext are
unreliable for all PDF types

Do you have evidence for that?

Do you actually mean that iText is unreliable for all PDF types, or that it is
unreliable for some PDF types? If the latter, what types? If the former,
I've never seen it be unreliable for any PDF usage I've observed of it.

What exactly do you mean by "unreliable"?

so the installed exe just makes sense to use.

To you.
