NAME

       printcap - 打印機相容性數據庫

總覽 SYNOPSIS

       printcap

描述 DESCRIPTION

       Printcaptermcap(5)  的簡單版,  用來描述  line  printers.  當用到  spool  系  統時,
       一定會去參考       printcap       這個檔.       允許動態地加入及刪除印表機.       在這資料
       庫中的每一段敘述代表一臺印表機.  This data base may not be substituted for, as is possible
       for termcap, because it may allow accounting to be bypassed.

       預設的印表機是  lp,  雖然環境變數  PRINTER   可能優於(override)此.   每一   個用到   spool
       的軟體都支援  -p 的選項, 用以選擇印表機. 如果想知道如何為一 臺印表機設定資料的討論, 請參照
       4.3 BSD Line Printer Spooler Manual.

       如果本地端印表機(local  line  printer)   driver   支援   indentation   的話,   daemon   將
       知道如何去用它.

過濾器 FILTERS

       lpd(8)  守護進程將創造出一個過濾的管線  (pipeline of filters) 來處理各個不同印 表機的檔案.
       過濾器將依照旗標來選擇將何者送到 lpr(1) .  管線的設定值有:
                  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 過濾器的用法是:
                  if [-c] -wwidth -llength -iindent -n login -h host acct-file

       -c 這個旗標只有在 -l 旗標有列在 lpr 中時纔可忽略. width 和 length 定義  了  page  的長和寬
       (from  pw  and pl respectively). -n 和 -h 可指定列印工作擁有者 的 login name 和 host name.
       Acct-file 將忽略 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.

       其它過濾器的呼叫用法如下:
                  filter -xwidth -ylength -n login -h host acct-file

       如果要用 pixels 為單位來定長寬的話, 用 px  和  py  這二個變數.   所有的過濾器都經由  stdin
       輸入檔案, stdout 輸出到印表機, 用 stderr 或 syslog(3) 來記錄(log), 而且不會忽略 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.
