We have used this filter when printing a file from a PC to postscript
printer on a ultrix machine. 


/* This is a simple filter, which puts carriage returns (13 dec, 015 oct, */
/*  0xD hex) before each new line (line feed = 10 dec, 012 oct, 0xA hex)  */
/*  and after control-d ( 4 dec) and strips any possible control-z's (DOS */
/*  end-of-file marks) off                                                                                                                        */
