GNU/Linux系统间共享
在作为打印服务器的GNU/Linux系统（服务器端）上安装好CUPS之后，建议您通过网页操作界面与另一个GNU/Linux系统（客户端）共享打印机；当然您也可以选择手动操作共享。
在启动cupsd之前，您需要保证avahi-daemon处于运行状态。
您的客户端需要支持Avahi主机名解析，否则客户端可能报错称“找不到打印机”("Unable to locate printer")。详情请参考avahi#Hostname resolution。
使用网页操作界面
用浏览器访问CUPS管理页面：http://localhost:631
点击页面上方的Administration按钮, 在Printer下选择“add printer”，将会自动检测已连接的打印机。如果打印机无法被检测，请尝试将打印机重启后重新检测。
打印机设置好之后，将Server下的"Share printers connected to this system"改为选中状态，然后点击下方的change settings保存修改。这时打印服务器将自动重启。
选择"Edit Configuration File"即可直接修改配置文件cups.conf。通过修改文件您可以选择仅将打印机共享到特定用户或IP地址，下文中有详细说明。
手动操作
在打印服务器端（即与打印机直接相连的那端）编辑配置文件 /etc/cups/cupsd.conf，使共享打印机的系统能连接到服务器端。比如添加如下内容：
<Location /> Order allow,deny Allow localhost Allow 192.168.0.* </Location>
其中“Allow”后面为允许与打印服务器相连的系统。"Allow all"将允许局域网内所有系统与打印服务器连接。
此外我们需要保证服务器端正在监听客户端所在的IP地址。在"# Listen <serverip>:631"之后添加如下内容（注意：“Listen”后面为服务器的IP地址，而非客户端IP地址）：
Listen 192.168.0.101:631
为了“让打印机在局域网中可见”("Show shared printers on the local network")，请添加如下内容以保证Browsing指令可以使用：
Browsing On
完成修改后重启CUPS。
在客户端的/etc/cups/client.conf文件中（如果文件不存在则新建）新建一行，将服务器的名称或IP地址添加到"ServerName"（服务器名称）后面：
ServerName 192.168.0.101
还有很多其他可行的配置方式，在http://localhost:631/help/network.html 中有详细介绍。
完成修改后重启CUPS。
注意: 在客户端添加打印机时，如果采用的是IPP协议（Internet Printing Protocol）, 请采用如下形式的URI： ipp://192.168.0.101:631/printers/<打印机名称>
如果您的客户端CUPS版本为1.6.x而服务器端CUPS版本<= 1.5.x
在CUPS 1.6及其之后的版本中, 客户端默认采用IPP 2.0。如果服务器端的CUPS版本<=1.5/IPP版本<= 1.1，由于客户端不会自动使用较早版本的通信协议，客户端将无法与服务器端交流。一个可行的方法是在/etc/cups/client.conf中添加如下内容(此方法于2013-05-07被指有误, 可以参考错误报告):
ServerName HOSTNAME-OR-IP-ADDRESS[:PORT]/version=1.1
Between GNU/Linux and Windows
Linux server - Windows client
Sharing via IPP
The preferred way to connect a Windows client to a Linux print server is using IPP. It is a standard printer protocol based on HTTP, allowing you all ways to profit from port forwarding, tunneling etc. The configuration is very easy and this way is less error-prone than using Samba. IPP is natively supported by Windows since Windows 2000.
To configure the server side proceed as described in the section above to enable browsing.
On the Windows computer, go to the printer control panel and choose to ‘Add a New Printer‘. Next, choose to give a URL. For the URL, type in the location of the printer:
http://host_ip_address:631/printers/printer_name
(where host_ip_address is the GNU/Linux server‘s IP address and printer_name is the name of the printer being connected to, you can also use the server‘s fully qualified domain name, if it has one, but you may need to set ServerAlias my_fully_qualified_domain_name in cupsd.conf for this to work).
Note: The add printer dialog in windows is quite sensitive to the path to the printer, the dialogue box itself suggests:
http://servername:631/printers/printer_name/.printer
which will work in a web-browser but not in the add printer dialogue. (At least, not when using cups as an ipp server). The syntax suggested above:
http://host_ip_address:631/printers/printer_name
will work.
After this, install the native printer drivers for your printer on the Windows computer. If the CUPS server is set up to use its own printer drivers, then you can just select a generic postscript printer for the Windows client(e.g. ‘HP Color LaserJet 8500 PS‘ or ‘Xerox DocuTech 135 PS2‘). Then test the print setup by printing a test page.
Sharing via Samba
If your client‘s Windows version is below Windows 2000 or if you experienced troubles with IPP you can also use Samba for sharing. Note of course that with Samba this involves another complex piece of software. This makes this way more difficult to configure and thus sometimes also more error-prone, mostly due to authentication problems.
To configure Samba on the Linux server, edit /etc/samba/smb.conf file to allow access to printers. File smb.conf can look something like this:
/etc/samba/smb.conf
[global]
workgroup=Heroes
server string=Arch Linux Print Server
security=user
[printers]
comment=All Printers
path=/var/spool/samba
browseable=yes
# to allow user ‘guest account‘ to print.
guest ok=no
writable=no
printable=yes
create mode=0700
write [email protected] root yourusername
That should be enough to share the printer, yet adding an individual printer entry may be desirable:
/etc/samba/smb.conf
[ML1250]
comment=Samsung ML-1250 Laser Printer
printer=ml1250
path=/var/spool/samba
printing=cups
printable=yes
printer [email protected] root yourusername
user client driver=yes
# to allow user ‘guest account‘ to print.
guest ok=no
writable=no
write [email protected] root yourusername
valid [email protected] root yourusername
Please note that this assumes configuration was made so that users must have a valid account to access the printer. To have a public printer, set guest ok to yes, and remove the valid users line. To add accounts, set up a regular GNU/Linux account and then set up a Samba password on the server. For instance:
# useradd yourusername # smbpasswd -a yourusername
After this, restart the Samba daemon.
Obviously, there are a lot of tweaks and customizations that can be done with setting up a Samba print server, so it is advised to look at the Samba and CUPS documentation for more help. The smb.conf.example file also has some good samples that might warrant imitating.
Windows server - Linux client
Warning: CUPS cannot handle spaces in printer URIs. If your Windows printer name or user passwords have spaces, CUPS will throw "lpadmin: Bad device-uri" error
Sharing via LPD
Windows 7 has a built-in LPD server - using it will probably be the easiest approach as it does neither require an installation of Samba on the client nor heavy configuration on the server. It can be activated in the Control Panel under Programs -> Activate Windows functions in the section Print services. The printer must have shared activated in its properties. Use a share name without any special characters like spaces, commas, etc.
Then the printer can be added in CUPS, choosing LPD protocol. The printer address will look like this:
# lpd://windowspc/printersharename
Before adding the printer, you will most likely have to install an appropriate printer driver depending on your printer model. Generic PostScript or RAW drivers might also work.
Sharing via IPP
As above, IPP is also the preferred protocol for printer sharing. However this way might be a bit more difficult than the native Samba approach below, since you need a greater effort to set up an IPP-Server on Windows. The commonly chosen server software is Microsoft‘s Internet Information Services (IIS).
Note: This section is incomplete. Here is a description how to set up ISS in Windows XP and Windows 2000, unfortunately in German [1]
Sharing via Samba
A much simpler way is using Window‘s native printer sharing via Samba. There is almost no configuration needed, and all of it can be done from the CUPS Backend. As above noted, if there are any problems the reason is mostly related to authentication trouble and Windows access restrictions.
On the server side enable sharing for your desired printer and ensure that the user on the client machine has the right to access the printer.
The following section describes how to set up the client, assuming that both daemons (cupsd and smbd) are running.
Configuration using the web interface
The Samba CUPS back-end is enabled by default, if for any reason it is not activate it by entering the following command and restarting CUPS.
# ln -s $(which smbspool) /usr/lib/cups/backend/smb
Next, simply log in on the CUPS web interface and choose to add a new printer. As a device choose "Windows Printer via SAMBA".
For the device location, enter:
smb://username:[email protected]/printer_name
Or without a password:
smb://[email protected]/printer_name
Make sure that the user actually has access to the printer on the Windows computer and select the appropriate drivers. If the computer is located on a domain, make sure the user-name includes the domain:
smb://username:[email protected]/hostname/printer_name
If the network contains many printers you might want to set a preferred printer. To do so use the web interface, go into the printer tab, choose the desired printer and select ‘Set as default‘ from the drop-down list.
Manual configuration
For manual configuration stop the CUPS daemon and add your printer to /etc/cups/printers.conf, which might for example look like this
/etc/cups/printers.conf
<DefaultPrinter MyPrinter> AuthInfoRequired username,password Info My printer via SAMBA Location In my Office MakeModel Samsung ML-1250 - CUPS+Gutenprint v5.2.7 # <= use ‘lpinfo -m‘ to list available models DeviceURI smb://username:[email protected]/printer_name # <= server URI as described in previous section State Idle Type 4 Accepting Yes Shared No JobSheets none none QuotaPeriod 0 PageLimit 0 KLimit 0 AllowUser yourusername # <= do not forget to change this OpPolicy default ErrorPolicy stop-printer </Printer>
Then restart the CUPS daemon an try to print a test page.
To set the preferred printer use the following command
# lpoptions -d desired_default_printer_name
