# Print text, postscript, or native printer language to arbitrary printer,
# designed as a quick for for the random printers that get hooked up to
# the NetBSD server and random Windows boxes around the office...
#
# Overview:
# - Overloads 'af' entry to contain printer type, and optional location.
# in the form 'type[.model][/smb/smb_dest]'. 'ps' for no gs filter.
# - Reads first 1k and calls 'file' to determine filetype.
# - Builds a spool command based on filetype:
# - If text and not postscript, use enscript text->postscript
# - If enscripted or postscript, use gs postscript->printer_format
# - Otherwise assumed to be native printer language (its your rope)
# - Open pipe to spool command, send first 1k, then rest of data
# - requires ghostscript, enscript, and samba if printing to smb hosts
#
# Sample printcap entries: (Remember to create spool dir [sd])
#
# HP deskjet named 'leaves' connected to smb host 'tea'.
# (using ghostscript 'hpdj' driver model 'unspec')
#
# leaves:\
# :sh:mx=0:if=@PREFIX@/libexec/if-psprint:lf=/var/log/lpd-errs:\
# :lp=/dev/null:sd=/var/spool/lpd/leaves:af=hpdj.unspec/smb/tea/leaves
