My reversion to lpd(8) includes foomatic-rip in "direct" mode, using the JetDirect port 9100.

1. This allows me to print PDFs as well as Postscript files, and
2. I can set print options by spool queue.

/etc/printcap:

# Default printer.  Postscript or PDF only, using foomatic-rip (print/cups-filters).

        :sd=/var/spool/output:\
        :lf=/var/log/lpd-errs:\
        :sh:

# Same printer, using No. 10 Envelope and manual feed.
# These are 4.25" high and 9.5" wide.
