NAME
printcap - 列表機相容性數據庫
總覽 SYNOPSIS
printcap
描述 DESCRIPTION
Printcap 是 termcap(5) 的□□版, 用□描述 line printers. □用到 spool 系 □□, 一定□去□考
printcap □□□. 允□□□地加入及□除印表□. 在□□料 □中的每一段□述代表一台印表□. This data base
may not be substituted for, as is possible for termcap, because it may allow accounting to
be bypassed.
□□的印表□是 lp, □然□境□□ PRINTER 可能□於(override)此. 每一 □用到 spool 的□□都支援 -p 的□□,
用以□□印表□. 如果想知道如何□一 台印表□□定□料的□□, □□照 4.3 BSD Line Printer Spooler
Manual.
相容性 CAPABILITIES
根□ termcap(5) □□案□出的描述.
Name Type Description
af str NULL name of accounting file
br num none if lp is a tty, set the baud
rate (ioctl(2) call)
cf str NULL cifplot data filter
df str NULL tex data filter (DVI format)
fc num 0 if lp is a tty, clear flag
bits (sgtty.h)
ff str ` 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(3)
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)
pw num 132 page width (in characters)
px num 0 page width in pixels
(horizontal)
py num 0 page length in pixels
(vertical)
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 /var/spool/lpd spool directory
sf bool false suppress form feeds
sh bool false suppress printing of burst
page header
st str status status file name
tf str NULL troff data filter (cat
phototypesetter)
tr str NULL trailer string to print when
queue empties
vf str NULL raster image filter
如果本地端印表□(local line printer) driver 支援 indentation 的□, daemon □ 知道如何去用它.
過濾器 FILTERS
lpd(8) 守護進程□□造出一□□□的管□ (pipeline of filters) □□理各□不同印 表□的□案. □□器□依照
旗□□□□□何者送到 lpr(1) . 管□的□定值有:
p pr | if regular text + pr(1)
none If regular text
c cf cifplot
d df DVI (tex)
g gf plot(3)
n nf ditroff
f rf Fortran
t tf troff
v vf raster image
if □□器的用法是:
if [-c] -wwidth -llength -iindent -n login -h host acct-file
-c □□旗□只有在 -l 旗□有列在 lpr 中□才可忽略. width 和 length 定□ 了 page 的□和□ (from pw
and pl respectively). -n 和 -h 可指定列印工作□有者 的 login name 和 host name. Acct-file
□忽略 printcap 中的描述.
If no if is specified, of is used instead, with the distinction that of is opened only
once, while if is opened for every individual job. Thus, if is better suited to
performing accounting. The of is only given the width and length flags.
其它□□器的呼叫用法如下:
filter -xwidth -ylength -n login -h host acct-file
如果要用 pixels □□位□定□□的□, 用 px 和 py □二□□□. 所有的□□器都□由 stdin □入□案, stdout
□出到印表□, 用 stderr 或 syslog(3) □□□(log), 而且不□忽略 SIGINT.
日誌 LOGGING
Error messages generated by the line printer programs themselves (that is, the lp*
programs) are logged by syslog(3) using the LPR facility. Messages printed on stderr of
one of the filters are sent to the corre- sponding lf file. The filters may, of course,
use syslog themselves.
Error messages sent to the console have a carriage return and a line feed appended to
them, rather than just a line feed.
