[求助] 无法使用"双面打印" (网络打印机的安装已经解决)

shinkansen

主题：网络打印机安装失败.hplip, cups表现都不太正常
(网络打印机的问题已经解决)

实验室局域网内最近添加了一台网络打印机，通过印机上的网口连入交换机，接入局域网。打印机的型号为 HP P2055n。Windows用户按照附赠的光盘“下一步”、“下一步”就能找到打印机。Linux用户就得自己折腾CUPS和hplip。但是，hp-setup配置通不过，提示找不到PPD文件(实际上所需文件是存在的)；后来改用CUPS的 Web Interface 添加打印机，添加成功，打印测试页成功，但是在gnome中无法看到，gnome-cups-manager提示无法连接到CUPS服务器。

我参照的是下面两份资料：
Getoo Wiki CUPS
http://en.gentoo-wiki.com/wiki/CUPS

Gentoo Wiki Hplip
http://www.gentoo-wiki.info/HPLIP

安装了hplip。其中，hplip 添加了cups, ppds的USE Flags. CUPS因为依赖关系，在安装hplip时被带了进来。我所安装的hplip、CUPS版本以及USE Flags如下：

net-print/hplip
Installed versions: 3.9.8 (cups cupsddk dbus gtk ppds snmp -doc -fax -minimal -parport -policykit -qt3 -qt4 -scanner)

net-print/cups
Installed versions:  1.3.10-r2 (X acl avahi dbus gnutls jpeg linguas_en linguas_zh_TW pam perl png ppds python samba ssl tiff zeroconf -java -kerberos -ldap -linguas_de -linguas_es -linguas_et -linguas_fr -linguas_he -linguas_id -linguas_it -linguas_ja -linguas_pl -linguas_sv -php -slp -static -xinetd)

按照CUPS Wiki的指示，以root身份运行hplip中的工具 hp-setup 配置打印机 (之前已经启动cups服务)：

一切看起来还算顺利：

然后，问题发生了：

复制代码

这就奇怪了，给2205dn用的PPD命名就在机子上：

1. 
   
2. find ./ -iname '*2055dn*'
   
3. ./share/ppd/HP/hp-laserjet_p2055dn-pcl3.ppd.gz
   
4. ./share/ppd/HP/hp-laserjet_p2055dn-ps.ppd.gz
   

复制代码

后来尝试了 hplip 的其他两个版本：
3.9.4b-r1 问题一模一样
2.8.6b-r1 根本找不到网络打印机

hplip暂时作罢，改用 CUPS 的 Web Interface 来配置：  http://localhost:631/

添加比较顺利，打印测试页成功，如图所示。

但是在 Gnome 应用程序的“打印”中无法看到这个打印机。耐着性子，装了一个gnome-cups-manager，但是，点开时提示“无法连接到CUPS服务器”，如图所示。

觉得匪夷所思，老子的CUPS明明是打开了，后来借用hplip的check.py，发现，hplip也认为CUPS是没有打开的。不知大家在安装HP网络打印机时有没有遇到这样的麻烦事？

16. HPLIP supplied tarball has the proper dependencies installed to successfully run.                                                      
    
17. 3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both compile- and      
    
18. run-time dependencies).

网络打印机安装成功：

参考了《Gentoo Samba3/CUPS HOWTO》
http://www.gentoo.org/doc/en/quick-samba-howto.xml

Here are common errors that may happen:

    * The hostname given as a parameter for -h and -H (PrintServer) often does not resolve correctly and doesn't identify the print server for CUPS/Samba interaction. If an error like: Warning: No PPD file for printer "CUPS_PRINTER_NAME" - skipping! occurs, the first thing you should do is substitute PrintServer with localhost and try it again.

查看了自己的 /etc/cups/client.conf，内容如下：
ServerName /var/run/cups/cups.sock

我改成了：
ServerName localhost

重启CUPS，再次运行hp-setup，这次打印机安装成功了。gnome-cups-manager也能顺利连上CUPS，并且可以方便的配置已经打印机属性。gnome-cups-manager也可以添加新的打印机，但是用起来明显没有hp-setup方便。

现在的新问题是：无法使用“双面打印”功能，这通常是在[打印] -> [高级]中提供的，现在这个选项打不开。普通Gnome程序如此，Acroread也是如此。

shinkansen

问题有了一些新的眉目，但是现在有些累了，决定放一放：

首先，可以通过“root”身份在 gnome-cups-manager 中调整Printer的属性，设为双面打印。

下面的网页对我帮助很大：

“Printing with Adobe Reader”
http://blogs.adobe.com/acroread/

在 Shell 中输入:

export ACRO_PRINT_DEBUG=1

然后在acroread中打开一个PDF，尝试Print, 点击 Property，则Shell中出现了下面的提示：

PPD not found - cupsGetPPD failed

文中也提到了几种典型的错误：
    *
          o Error : dlopen of libcups failed
          o Possible Problem : Libcups not in LD_LIBRARY_PATH
          o Solution : Make sure LD_LIBRARY_PATH points to the libcups
    *
          o Error : No destinations returned by cupsGetDests
          o Possible Problem : No printers configured on the machine.
          o Solution : Configure the printer using the CUPS web UI.
    *
          o Error : PPD not found - cupsGetPPD failed
          o Possible Problem : No ppd available for the printer or ppd accidentally moved
          o Solution : Re-launch reader, check for the ppd or reconfigure the printer
    *
          o Error : Error opening PPD - ppdOpenFile failed
          o Possible Problem : No ppd available for the printer or ppd accidentally moved
          o Solution : Re-launch reader, check for the ppd or reconfigure the printer


看看，什么时候有时间再折腾折腾。

ProgramFan

以前遇到过类似的问题，不知道是否对你有帮助：

在打印机管理里，有一项叫 duplex unit 的，默认不会被选上，选上后就能设置双面打印了。见 http://localhost:631 之打印机管理。

ProgramFan

多说一句：HP 的打印机驱动完全没有必要那么麻烦，只要安装了 cups，直接使用 cups 自带的 hp generic PCL 4/5 或 hp generic PCL 6 就行，我在 hp laserjet p3005d 上使用 hp generic pcl 6，正常，哈哈。

tomguy

我用的是hp1020打印机，很久以前记得一个说明文件中说的是不支持双面打印的。难到说现在可以了？

shinkansen

问题已经莫名其妙地解决了。所用软件的版本：

net-print/cups-1.3.11-r1 (X acl avahi dbus gnutls jpeg linguas_en linguas_zh_TW pam perl png ppds python samba ssl tiff zeroconf -java -kerberos -ldap -linguas_de -linguas_es -linguas_et -linguas_fr -linguas_he -linguas_id -linguas_it -linguas_ja -linguas_pl -linguas_sv -php -slp -static -xinetd)

安装网络打印机的过程我还是倾向于使用hplip提供的hp-setup。一切顺利，ppd也顺利找到了。
