   3: # Wrapper script for postprint on Solaris
   4: #  
   5: # Pass files through the Solaris postprint utility, 
   6: # but only if they are not already postscript.  
   7: # Output is then piped directly to lp or lpr
   8: #
   9: # We do not process any files unless a default printer 
  10: # has been selected.  The search list is $LPDEST, 
  11: # $PRINTER, the _default line in $HOME/.printers
  12: # A printer may also be specified by option "-P printer"
  13: #
  14: # Any other options are passed on to postprint.  
  15: # This script knows about the postprint # options so 
  16: # it can skip over them and get to the filenames
  17: # 
  18: # PROBLEMS
  19: # - cat multiple postscript files into lpr is NOT 
  20: #  the same as passing multiple filenames to postprint
  21: #  and piping the output to lpr.  Postprint only generates
  22: #  one header, then multiple sets of data.  
  23: #  This is why we need to insert each named file into 
  24: #  the print queue directly.
