USE Linux 10 PDF打印机配置小结

首先需确认已安装CUPS，ghostscript-library(rpm)，这是系统自带的没装自己安装先。
1. 配置CUPS

编辑/etc/cups/cups.conf，把相关项改成如下配置：

User lp
Group lp
RunAsUser No

<Location /admin>
AuthType Basic



重启CUPS服务：rccups restart

2. 配置CUPS支持工具(backends)

添加一个文件/usr/lib/cups/backend/pdf-writer, 内容如下：

#!/bin/sh

把该文件的权限改为755:

# chmod 755 /usr/lib/cups/backend/pdf-writer


准备好PDF的保存目录：
# mkdir -p /export/share/pdf
# chmod -R 777 /export
接下来需要选择ppd文件。你可以选择系统自带的，如下：

# cd /usr/share/cups/model
# gunzip -d PostScript-level2.ppd.gz
# lpadmin -p CUPS-PDF -v pdf-writer:/export/share/pdf/ -E -P \
/usr/share/cups/model/Postscript-level2.ppd -D "PDF Writer for CUPS" \
-L "PDF Backend /usr/lib/backend/pdf-writer"



也可以从[url]http://www.adobe.com/support/downloads/thankyou.jsp?ftpID=204&fileID=204[/url]下载Adobe公司的ppd（据说效果更好些），然后：

# unzip -d adobe.zip
# cp Adobe/ADIST5.PPD /usr/share/cups/model/Acrobat-Distiller.ppd
# lpadmin -p CUPS-PDF -v pdf-writer:/export/share/pdf/ -E -P \
/usr/share/cups/model/Acrobat-Distiller.ppd -D "PDF Writer for CUPS" \
-L "PDF Backend /usr/lib/backend/pdf-writer"


登入CUPS的管理界面 http://localhost:631/admin，应该可以看到添加的CUPS-PDF打印机了。
打印一个文件看看，在/export/share/pdf可看到打印结果。

3. 让打印结果保存到用户的HOME目录

编辑/usr/lib/cups/backend/pdf-writer，设置USERMODE="on"，改变/etc/cups/cupsd.conf，把User改为root，重启CUPS: rccups restart

这样用户打印的PDF文件会保存在$HOME/PDF下面。
