\bp is a simplified version of the _
\bt_
\be_
\br_
\bm_
\bc_
\ba_
\bp(5) data base
used to describe line printers. The spooling system
accesses the _
\bp_
\br_
\bi_
\bn_
\bt_
\bc_
\ba_
\bp file every time it is used, allowing
dynamic addition and deletion of printers. Each entry in
the data base is used to describe one printer. This data
base may not be substituted for, as is possible for _
\bt_
\be_
\br_
\bm_
\bc_
\ba_
\bp,
because it may allow accounting to be bypassed.
The default printer is normally _
\bl_
\bp, though the environment
variable PRINTER may be used to override this. Each spool-
ing utility supports an option, -
\b-P
\bP_
\bp_
\br_
\bi_
\bn_
\bt_
\be_
\br, to allow explicit
naming of a destination printer.

af str NULL name of accounting file

ff str ``\f'' string to send for a form feed
fo bool false print a form feed when device is opened
fs num 0 like `fc' but set bits
gf str NULL graph data filter (plot (3X) format)
hl bool false print the burst header page last
ic bool false driver supports (non standard) ioctl to indent printout
if str NULL name of text filter which does accounting
lf str ``/dev/console'' error logging file name
lo str ``lock'' name of lock file
lp str ``/dev/lp'' device name to open for output
mx num 1000 maximum file size (in BUFSIZ blocks), zero = unlimited
nd str NULL next directory for list of queues (unimplemented)
nf str NULL ditroff data filter (device independent troff)
of str NULL name of output filtering program
pc num 200 price per foot or page in hundredths of cents
pl num 66 page length (in lines)

rf str NULL filter for printing FORTRAN style text files
rg str NULL restricted group. Only members of group allowed access
rm str NULL machine name for remote printer
rp str ``lp'' remote printer name argument
rs bool false restrict remote users to those with local accounts
rw bool false open the printer device for reading and writing
sb bool false short banner (one line only)
sc bool false suppress multiple copies
sd str ``/usr/spool/lpd'' spool directory

tr str NULL trailer string to print when queue empties
vf str NULL raster image filter
xc num 0 if lp is a tty, clear local mode bits (tty (4))
xs num 0 like `xc' but set bits
If the local line printer driver supports indentation, the
daemon must understand how to invoke it.

The _
\bl_
\bp_
\bd(8) daemon creates a pipeline of _
\bf_
\bi_
\bl_
\bt_
\be_
\br_
\bs to process
files for various printer types. The filters selected
depend on the flags passed to _
\bl_
\bp_
\br(1). The pipeline set up
-p pr | if regular text + _
\bp_
\br(1)
-g gf _
\bp_
\bl_

\bt(3)
The i
\bif
\bf filter is invoked with arguments:
_
\bi_
\bf [ -
\b-c
\bc ] -
\b-w
\bwwidth -
\b-l
\bllength -
\b-i
\biindent -
\b-n
\bn login -
\b-h
\bh host
The -
\b-c
\bc flag is passed only if the -
\b-l
\bl flag (pass control
characters literally) is specified to _
\bl_
\bp_
\br. _
\bW_
\bi_
\bd_
\bt_
\bh and _
\bl_
\be_
\bn_
\bg_
\bt_
\bh
specify the page width and length (from p
\bpw
\bw and p
\bpl
\bl respec-
tively) in characters. The -
\b-n
\bn and -
\b-h
\bh parameters specify the
login name and host name of the owner of the job respec-
tively. _
\bA_
\bc_
\bc_
\bt-_
\bf_
\bi_
\bl_
\be is passed from the a
\baf
\bf _
\bp_
\br_
\bi_
\bn_
\bt_
\bc_
\ba_
\bp entry.
If no i
\bif
\bf is specified, o
\bof
\bf is used instead, with the distinc-
tion that o
\bof
\bf is opened only once, while i
\bif
\bf is opened for
every individual job. Thus, i
\bif
\bf is better suited to
PRINTCAP(5) 1986 PRINTCAP(5)
performing accounting. The o
\bof
\bf is only given the _
\bw_
\bi_
\bd_
\bt_
\bh and
_
\bl_
\be_
\bn_
\bg_
\bt_
\bh flags.
All other filters are called as:
_
\bf_
\bi_
\bl_
\bt_
\be_
\br -
\b-x
\bxwidth -
\b-y
\bylength -
\b-n
\bn login -
\b-h
\bh host acct-file
where _
\bw_
\bi_
\bd_
\bt_
\bh and _
\bl_
\be_
\bn_
\bg_
\bt_
\bh are represented in pixels, specified
by the p
\bpx
\bx and p
\bpy
\by entries respectively.
All filters take _
\bs_
\bt_
\bd_
\bi_
\bn as the file, _
\bs_
\bt_
\bd_
\bo_
\bu_
\bt as the printer,
may log either to _

Error messages generated by the line printer programs them-
selves (that is, the _
\bl_
\bp* programs) are logged by _
\bs_
\by_
\bs_
\bl_
\bo_
\bg(3)
using the _
\bL_
\bP_
\bR facility. Messages printed on _
\bs_
\bt_
\bd_
\be_
\br_
\br of one
of the filters are sent to the corresponding l
\blf
\bf file. The
filters may, of course, use _
\bs_
\by_
\bs_
\bl_
\bo_
\bg themselves.
Error messages sent to the console have a carriage return
and a line feed appended to them, rather than just a line
