rather than trying to interpret command line options yourself, just
pass them all on to lpr directly:
#!/bin/sh
htmldoc --header ..... | lpr "$@"
so "rrhtml -P foo@bar" ends up piping to "lpr -P foo@bar".
if you're doing this on some arcane shell (and you may well be if
you're somewhere where you need #!/bin/ksh), you might need to use
${1+"$@"} instead to correctly cope with the case where there's no
arguments passed.
