SMB HOWTO : 分享 Windows 印表机给 Linux 机器

9. 分享 Windows 印表机给 Linux 机器
为了分享 Windows 机器上的印表机, 你必须做以下步骤:
a) 你必须在 /etc/printcap 内有适当的记录,而且他们必须与当地
目录结构 (像 spool 目录等) 相符合.
b) 你必须有 script 档 /usr/bin/smbprint. 这会随附在 Samba
source, 但不是随附於所有 Samba binary 发行套件. 一个稍微修
改版本在以下讨论.
c) 如果你想要转换 ASCII 档到 Postscript,你必须有netscript,
或与其等效的. netscipt 是一种 Postscript 转换器而且一般是安
装在 /usr/bin.
d) 你可以希望藉由有易於使用的 frond end 来使 Samba 列印更容
易. 一种用於处理 ASCII, Postscript 或建立 Postscript 的简单
perl script 在下面给定.
以下 /etc/printcap 项目用在 Windows NT 主机上 HP 5MP 印表
机. 这些项目如下:
cm - comment
{说明}
lp - device name to open for output
{为了输出,而要开启的设备名称}
sd - the printer's spool directory (on the local machine)
{印表机的 spool 目录 (在当地的机器上)}
af - the accounting file
{帐号档案}
mx - the maximum file size (zero is unlimited)
{最大档案大小 (零表示没限制)}
if - name of the input filter (script)
{输入过滤之名称 (script)}
要取得更多资讯,请看 Printing HOWTO 或者关於 printcap 的 man
page.
# /etc/printcap
#
# //zimmerman/oreilly via smbprint
#
lp:\
:cm=HP 5MP Postscript OReilly on zimmerman:\
:lp=/dev/lp1:\
:sd=/var/spool/lpd/lp:\
:af=/var/spool/lpd/lp/acct:\
:mx#0:\
:if=/usr/bin/smbprint:
请确定 spool 和 accounting{帐号} 的目录存在且可写入. 请确信
某行有适当的路径指到 smbprint script (在下面会给) 而且确定
适当的设备被指到 ( /dev 下某个档).
下个是 smbprint script 本身. 它通常被摆在 /usr/bin 而且是因
为 Andrew Tridgell 的缘故,而据我所知是他创造了 Samba. 它随
附在 Samba source 发行套件, 但在某些 binary 发行套件并没有,
所以在这我再造一个.
你可以希望仔细地看这个. 有某些较小的修改已经证明它们是很有
用的.
#!/bin/sh -x
# This script is an input filter for printcap printing on a unix machine. It
# uses the smbclient program to print the file to the specified smb-based
# server and service.
# For example you could have a printcap entry like this
#
# smb:lp=/dev/null:sd=/usr/spool/smb:sh:if=/usr/local/samba/smbprint
#
# which would create a unix printer called "smb" that will print via this
# script. You will need to create the spool directory /usr/spool/smb with
# appropriate permissions and ownerships for your system.
# Set these to the server and service you wish to print to
# In this example I have a WfWg PC called "lapland" that has a printer
# exported called "printer" with no password.
#
# Script further altered by hamiltom@ecnz.co.nz (Michael Hamilton)
# so that the server, service, and password can be read from
# a /usr/var/spool/lpd/PRINTNAME/.config file.
#
# In order for this to work the /etc/printcap entry must include an
# accounting file (af=...):
#
# cdcolour:\
# :cm=CD IBM Colorjet on 6th:\
# :sd=/var/spool/lpd/cdcolour:\
# :af=/var/spool/lpd/cdcolour/acct:\
# :if=/usr/local/etc/smbprint:\
# :mx=0:\
# :lp=/dev/null:
#
# The /usr/var/spool/lpd/PRINTNAME/.config file should contain:
# server=PC_SERVER
# service=PR_SHARENAME
# password="password"
#
# E.g.
# server=PAULS_PC
# service=CJET_371
# password=""
#
# Debugging log file, change to /dev/null if you like.
#
logfile=/tmp/smb-print.log
# logfile=/dev/null
#
# The last parameter to the filter is the accounting file name.
#
spool_dir=/var/spool/lpd/lp
config_file=$spool_dir/.config
# Should read the following variables set in the config file:
# server
# service
# password
# user
eval `cat $config_file`
#
# Some debugging help, change the >> to > if you want to same space.
#
echo "server $server, service $service" >> $logfile
(
# NOTE You may wish to add the line `echo translate' if you want automatic
# CR/LF translation when printing.
echo translate
echo "print -"
cat
) | /usr/bin/smbclient "\\\\$server\\$service" $password -U $user -N -P >> $logfile
大部分 linux 发行套件随附 nenscript 其用来转换 ASCII 文件成
Postscript. 以下 perl script 经由 smbprint 使更容易提供一种
简单介面给 linux 的列印.
Usage: print [-a|c|p] <filename>
-a prints <filename> as ASCII
-c prints <filename> formatted as source code
-p prints <filename> as Postscript
If no switch is given, print attempts to
guess the file type and print appropriately.
使用 smbprint 来列印 ASCII 档案便於截断过长的行. 如果可能的
话,这个 script 截断长行於空白键处(取代在字的中间).
格式化过的原始码是被 nenscript 处理过. 它处理 ASCII 档而且
用个特选的标头(像 date,filename等)格式化成两栏. 它也可计算
行数. 使用这当作例子, 其他格式型态可以达成的.
Postscript 文件已经适当地格式化了,所以它们直接通过.

# Script to print to oreilly which is currently on zimmerman

# ASCII - ensures that lines longer than $line_length characters wrap on
# whitespace.

# Code - Formats in Postscript (using nenscript) to display
# properly (landscape, font, etc).
