Yes, the problem is that lwsrv passes character codes that happen to be
ASCII escape characters (like the Apple symbol and check mark) without
conversion.  Then, many line printer spooler programs (like BSD lpr)
strips control characters.

Here is a patch that I sent to Columbia long ago, but it never got anywhere.

P.S. Thanks for using my macps program.
