This data base may not be substituted for, as is possible for termcap, because it may allow accounting to be bypassed. .PP 预设的印表机是 lp, 虽然环境变数 PRINTER 可能优于(override)此. 每一 个用到 spool 的软体都支援 -p 的选项, 用以选择印表机. 如果想知道如何为一 台印表机设定资料的讨论, 请参照 4.3 BSD Line Printer Spooler Manual. .SH "相容性 CAPABILITIES" 根据 .BI termcap(5) 对档案输出的描述. .nf 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 `\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(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.

Acct-file 将忽略 printcap 中的描述. .PP 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. .PP 其它过滤器的呼叫用法如下: .nf filter -xwidth -ylength -n login -h host acct-file .fi .PP 如果要用 pixels 为单位来定长宽的话, 用 px 和 py 这二个变数. 所有的过滤器都经由 stdin 输入档案, stdout 输出到印表机, 用 stderr 或 .B syslog(3) 来记录(log), 而且不会忽略 SIGINT. .SH "日志 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. .PP Error messages sent to the console have a carriage return and a line feed appended to them, rather than just a line feed. .SH "参见 SEE ALSO" termcap(5), lpc(8), lpd(8), pac(8), lpr(1), lpq(1), lprm(1) .br 4.3 BSD Line Printer Spooler Manual. .SH "历史 HISTORY" The printcap file format appeared in 4.2BSD.. .SH "[中文版维护人]" .B 中原资管森林站 .\" -- .\" 啾~~~ ^_^ .\" u8313115@mis.cycu.edu.tw .\" http://140.135.137.1/~u8313115/ .\" 中原资管森林站:140.135.137.11 .SH "[中文版最新更新]" .B 1997.01.01 .SH "《中国linux论坛man手册翻译计划》:" .BI http://cmpp.linuxforum.net .SH "跋" .br 本页面中文版由中文 man 手册页计划提供。 .br 中文 man 手册页计划：\fBhttps://github.com/man-pages-zh/manpages-zh\fR
