Reading spool file with Java

Based on code from the java400-l archives, I've been trying to read a
spool file using Java with the Java Toolbox. The following code works,
but there is a lot of "junk" mixed in with the report text. I'm pretty
sure this "junk" is printer control info. How do I eliminate it or parse
it so I will be left with only the human-readable text?

I'm not sure which kind of inputStream I need. The spool file says it is
for device type *SCS.

try {
System.out.println("Connecting to iSeries...");
AS400 sys = new AS400("mysys", "myuser", "mypwd");
System.out.println("Connected to iSeries.");

SpooledFile sf = new SpooledFile(sys,"JOBNAME",000006,"MYJOB"
,"MYUSER", "459688");
//PrintObjectInputStream inputStream =
sf.getInputACIFMergedStream(true);
PrintObjectInputStream inputStream = sf.getInputStream();
BufferedReader d = new BufferedReader(new
InputStreamReader(inputStream,"CP037"));
String data ="";
while((data = d.readLine() )!=null)
{
System.out.println (data);
}
} catch (java.lang.Exception e) {
System.err.println(e.getMessage());
}

Thanks,
