Function:   SubmitFile()

               When one has made sure DOS' PRINT is installed
               (using PrintThere()), one can submit files to the
               print queue for later printing. These files are
               put on a resident print queue and are printed in
               order, without having to bother about them.

   Syntax:     SubmitFile(<cFileName>)

   Arguments:  <cFileName> is the file you want to print. It's better
               to submit a full path, as the program may have
               changed the drive or directory when the file is
               going to be printed. You can use the function
               Qualify() found in this library to expand a
               filename to it's full path name.

   Returns:    a code where 0 indicates no error: file queued
               succesfully. Other numbers indicate an error, the
               number is the DOS error code.

   Usage:      if PrintThere()
                    SubMitFile( Qualify(FileName) )
               endif
