CUPS是蘋果公司發展的一套開源標準的列印系統，其支援MacOSX以及其他Unix-like作業系統，其使用"Internet Printing Protocol"並且對大部分的雷射印表機、噴墨印表機提供完整的列印服務。CUPS遵循GNU GPL條款。雖然也有很多列印軟體(例：LPRNG)，但是CUPS仍然是相對主流，而且簡單操作。許多Linux的發行板(包括Arch)都已經預設CUPS為預設列印系統。
tail -n 100 -f /var/log/cups/error_log
D = Debug(臭蟲) E = Error(錯誤) I = Information(資訊) etc...
在這裡'/var/log/cups/page_log'每次成功列印都會列出資訊 在這裡'/var/log/cups/access_log'列出所有CUPS http1.1服務的狀態
- 之後CUPS會察看你的列印機的PPD檔案(printer description)，再決定如何把.ps檔案轉換成印表機能了解的語言，像是PJL、PCL...等。這個步驟一般需要ghostscript。

# pacman -S samba
# modprobe usblp （2.6.x 核心） # modprobe printer （2.4.x 核心） # tail /var/log/messages.log （看看安裝成功了沒有）

Foomatic是一個資料庫驅動的列印系統，它將Unix下的通用後臺列印系統與開源的印表機驅動整合在一起。 只要有任一在開源驅動下能夠正常工作的印表機，它就能支援了。它支援CUPS, LPRng, LPD, GNUlpr, Solaris LP, PPR, PDQ, CPS 這些底層的列印系統，也能直接列印（既是驅動也是列印工具）。 Foomatic列印速度快，列印質量也挺不錯。不過缺點是，有個別的印表機可能沒有PPD檔案驅動。
# pacman -S foomatic-***
Foomatic包含五個安裝包： foomatic-filters (幫助後臺列印系統將PostScript轉成印表機語言)， foomatic-db (foomatic-db-engine生成PPD檔案時要用到的一切資料)， foomatic-db-PPD (已經獲支援的列印驅動) foomatic-db-engine (將 Foomatic XMLo資料庫中的數據生成PPD檔案)， foomatic-db-hpijs (專為HP列印驅動生成Foomatic XML 數據)。
惠普DeskJet, OfficeJet, Photosmart, Business Inkjet 和一些 LaserJet 印表機型號，需要安裝hplip。只用於惠普印表機。 也可同時安裝上面的Foomatic，對比一下兩者的列印速度。
# pacman -S hplip
也許以上的列印驅動仍然不行（不過安裝foomatic一定是必要的，能提高列印速度）。在設定CUPS時（即將講到） 沒有找到自己的印表機型號。那麼可能還需要接著安裝Gutenprint。 Gutenprint 是GIMP的列印擴充功能模組，過去叫"gimp-print"，它能夠為GIMP提供流行的列印驅動，能 讓佳能、愛普生、惠普、利盟、索尼、奧林巴斯，以及其他基於PCL技術的印表機，列印出更出色的品質。用於高品質的圖像列印是在好不過了。 它支援的印表機型號列表可見於：http://gutenprint.sourceforge.net/p_Supported_Printers.php3 不過Gutenprint的列印品質是沒得說，但速度就不敢恭維了。但有foomatic的支援就會快很多。
# pacman -S gutenprint
在 X 下設定 CUPS
列印基礎系統CUPS和列印驅動安裝好的，就要開始設定印表機了。 可以通過設定CUPS來設定印表機。設定CUPS的方法適用於一切印表機及其驅動。因此推薦使用。 進入X，打開一個網頁瀏覽器，訪問： http://localhost:631 （也可以用在/etc/hosts中設置好的hostname來代替localhost） 按照提示，一步一步的設定好印表機： Manage Printers ---> Add Printer ---> root密碼驗證 ---> 輸入印表機名稱 ---> 選擇設備類型 （印表機型號及其連接介面：USB埠 or 並列埠印表機） ---> 選擇你的印表機 ---> 通過印表機型號來選擇適當的印表機驅動，並Add （如果列印驅動的名稱中出現了foomatic字樣，一定要優先選擇） ---> 列印選項的設置 ---> 完成

Linux 對 Linux
Once you have CUPS setup on your Linux print server, sharing the printer with another Linux box is relatively easy. There are several ways to configure such a scenario, here we will describe the manual setup. On the server computer (the one managing and connecting to the printer) simply open up the /etc/cups/cupsd.conf file and allow access to the server by modifying the location lines. For instance:
<Location /> Order Deny,Allow Deny From All Allow From 127.0.0.1 Allow From 10.0.0.* </Location>
You will also need to make sure the server is listening on the IP address your client will be addressing. Add the following line after "Listen localhost:631":
using your server's IP address instead of 10.0.0.1.
Add the IP address of the client computer by doing Allow From client_ip_address. After you make your modifications, you will want to restart CUPS by doing:
# /etc/rc.d/cupsd restart
On the client side, open up /etc/cups/client.conf and edit the ServerName option to match the ip address or the name of your server. For instance I named my server beast and have entry in my hosts file to point to it. So in my client.conf file, I just edited this line:
Next, run the following command to update the client computer:
You should see something like this:
ml1250 is ready no entries
There are more configuration possibilities including an automatic configuration which are described in detail on http://localhost:631/sam.html#CLIENT_SETUP (this link works on your printer server).
when prompted for username and password use root to access then follow the instructions from here http://www.digitalhermit.com/linux/printing/ if its a TCP/IP printer use Jetdirect
That's it for Linux to Linux printer sharing.
Linux to Windows
If you are connected to a Windows print server (or any other Samba capable print server), you can skip the section about kernel modules and such. All you have to do is start the CUPS daemon and complete the web interface as specified in section 3.3 and 3.4. Before this, you need to activate the Samba CUPS backend. You can do this by entering the following command:
# ln -s `which smbspool` /usr/lib/cups/backend/smb
Note that the symbol before is ` (underneath the ~ on a standard US keyboard) and not '. After this, you will have to restart CUPS using the command specified in the previous section. Next, simply login into the CUPS web interface and choose to add a new printer. For device, there should be an option that says something to the effect Windows Printer Via Samba near the button of the device list. For the device location enter:
Or without a password:
Make sure that the user actually has access to the printer on Windows computer. Select the appropriate drivers and that's about it. If the computer is located on a domain, make sure the username includes the domain:
Note: if your network contains many printers use "lpoptions -d your_desired_default_printer_name" to set your preferred printer
Note: I, thepizzaking, was having 'NT_STATUS_ACCESS_DENIED' errors and to fix them I needed to use a slightly different syntax:
Windows to Linux
Sometimes, you might want to allow a Windows computer to connect to your computer. There are a few ways to do this, and the one I am most familiar with is using Samba. In order to do this, you will have to edit your /etc/samba/smb.conf file to allow access to your printers. Your smb.conf can look something like this:
[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 list = @adm root neocephas
That should be enough to share your printer, but you just might want to add an individual printer entry:
[ML1250] comment = Samsung ML-1250 Laser Printer printer=ml1250 path = /var/spool/samba printing = cups printable = yes printer admin = @admin root neocephas user client driver = yes # to allow user 'guest account' to print. guest ok = no writable = no write list = @adm root neocephas valid users = @adm root neocephas
Please note that in my configuration I made it 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, you must setup a regular Linux account and then setup a Samba password on the server. For instance:
# useradd neocephas # smbpasswd -a neocephas
After setting up any user accounts that you need, you will also need to set up the samba spool folder:
# mkdir /var/spool/samba # chmod 777 /var/spool/samba
The next items that need changing are /etc/cups/mime.convs and /etc/cups/mime.types:
# The following line is found at near the end of the file. Uncomment it. application/octet-stream application/vnd.cups-raw 0 -
# Again near the end of the file. application/octet-stream
The changes to mime.convs and mime.types are needed to make CUPS print Microsoft Office document files. Many people seem to need that.
After this restart your Samba daemon:
# /etc/rc.d/samba restart
Obvious, there are a lot of tweaks and customization that can be done with setting up a Samba print server, so I advise you to look at the Samba and CUPS documentation for more help. The smb.conf.example file also has some good samples to that you might want to look at.
Windows 2000 and Windows XP to Linux
For the most modern flavors of Windows an alternative way of connecting to your Linux printer server is to use the CUPS protocol directly. The Windows client will need to be using Windows 2000 or Windows XP. Make sure you allows the clients to access the print server by editing the location settings as specified in section 4.1.
On the Windows computer, go to the printer control panel and choose to Add a New Printer. Next, choose to give an url. For the url type in the location of your printer:
where host_ip_address is the Linux server's IP address and printer_name is the name of the printer you are connecting to. After this, install the printer drivers for the Windows computer. If you setup the CUPS server to use its own printer drivers, then you can just select a generic postscript printer for the Windows client. You can then test your print setup by printing a test page.
Others to Linux, Linux to others
More information on interfacing CUPS with other printing systems can be found in the CUPS manual, e.g. on http://localhost:631/sam.html#PRINTING_OTHER
Alternative CUPS Interfaces
If you are a GNOME user, you can manage and configure your printer by using the gnome-cups-manager.
Update: this package is now available through pacman if you have the "community" repository uncommented in /etc/pacman.conf
pacman -S gnome-cups-manager
The package is also still available from the AUR.
KDE users can modify their printers from the Control Center. Both should refer the those desktop environments' documentation for more information on how to use the interfaces.
There is also. It is in the [extra] repository.
PDF Virtual Printer
A nice little package that I submitted to the incoming folder (ftp://ftp.archlinux.org/incoming) is CUPS-PDF. This package allows one to setup a virtual printer that will generate a PDF from anything sent to it. For example, I wrote this document in AbiWord and then printed it to the Virtual Printer which generated a PDF in my /var/spool/cups-pdf/neocephas folder. Obviously, this package is not necessary, but it can be quite useful. After downloading the package from the FTP server and installing it, you can set it up as you would for any other printer in the web interface. Select Virtual PDF Printer as the device and choose Postscript -> Postscript Color Printer for the drivers.

This section is dedicated to specific problems and their solutions. If you managed to get some unusual printer working, please put the solution here.
Printing does not work/aborts with the HP Deskjet 700 Series Printers.
- The solution is to install pnm2ppa printer filter for the HP Deskjet 700 series. Without this the print jobs will be aborted by the system. A PKGBUILD for AUR can be found in the AUR.
Getting HP LaserJet 1010 to work
I had to compile ghostscript myself because ESP gs in rep was 7.07 and had not fixed some bugs like ESP 8.15.1 had. I never downloaded 'foomatic' in rep. I think that is an old package.
$ pacman -Qs cups a2ps psutils foo ghost local/cups 1.1.23-3 The CUPS Printing System local/a2ps 4.13b-3 a2ps is an Any to PostScript filter local/psutils p17-3 A set of postscript utilities. local/foomatic-db 3.0.2-1 Foomatic is a system for using free software printer drivers with common spoolers on Unix local/foomatic-db-engine 3.0.2-1 Foomatic is a system for using free software printer drivers with common spoolers on Unix local/foomatic-db-ppd 3.0.2-1 Foomatic is a system for using free software printer drivers with common spoolers on Unix local/foomatic-filters 3.0.2-1 Foomatic is a system for using free software printer drivers with common spoolers on Unix local/espgs 8.15.1-1 ESP Ghostscript
I also had to set LogLevel in /etc/cups/cupsd.conf to debug2 before i saw that I missed some "Nimbus" fonts. Then I had to rename & put them where the log told me to. Some fancy google searching had to be applied, example: http://www.google.com/search?q=n019003l+filetype%3Apfb since the fonts turned out to be proprietary (i'm sure windows comes with these default). Nevertheless after downloading them(about 7 fonts) and putting them in the correct folder printing started working.
Before that i were getting all the errors said here: http://linuxprinting.org/show_printer.cgi?recnum=HP-LaserJet_1010 'Unsupport PCL' etc...
I'm sure it could have worked with ESP gs 7.07 too(in rep) if i was smart enough to turn on DebugLevel2 sooner :/ UPDATE: yeah it did... maybe this info is useful for someone else though.. sorry for the inconvenience.
Getting HP LaserJet 1020 to work
After a lot of tries with hplib and gutenprint I finally found the solution to get my printer HP Laserjet 1020 printing.
First of all you only need to install cups and ghostscript. Then follow the link on http://www.linuxprinting.org/show_printer.cgi?recnum=HP-LaserJet_1020 to the http://foo2zjs.rkkda.com/ printer driver page and follow the install instructions. Log in as root. After you downloaded the package and extracted the archive, change into the foo2zjs directory. Now you can follow the original installation instructions with a minor modification to change the userid for printing:
$ make $ ./getweb 1020
Open the Makefile
$ nano Makefile
and search for the line
and modify it to
then continue with the script
$ make install $ make install-hotplug $ make cups
Or you can use the package foo2zjs from AUR and modify the PKGBUILD: change the line
(or if you're setting another printer change this line to what you need).
As a last step add and configure the printer in the CUPS manager. The printer should be recognized automatically. It works fine for root and all users. When booting the operating system, the printer is initialized and indicates its working.
Printer connected to an Airport Express Station
The first thing to do is to scan the airport express station. It seems that there are different addresses depending on the model.
[root@somostation somos]# nmap 192.168.0.4 Starting Nmap 4.20 ( http://insecure.org ) at 2007-06-26 00:50 CEST Interesting ports on 192.168.0.4: Not shown: 1694 closed ports PORT STATE SERVICE 5000/tcp open UPnP 9100/tcp open jetdirect 10000/tcp open snet-sensor-mgmt MAC Address: 00:14:51:70:D5:66 (Apple Computer) Nmap finished: 1 IP address (1 host up) scanned in 25.815 seconds
With my station the port is 9100. The airport station is accessed like an HP JetDirect printer. After, you can edit your printer.conf file in this way:
# Printer configuration file for CUPS v1.2.11 # Written by cupsd on 2007-06-26 00:44 <Printer LaserSim> Info SAMSUNG ML-1510 gdi Location SomoStation DeviceURI socket://192.168.0.4:9100 State Idle StateTime 1182811465 Accepting Yes Shared Yes JobSheets none none QuotaPeriod 0 PageLimit 0 KLimit 0 OpPolicy default ErrorPolicy stop-printer </Printer>
It should work. I had a few problems. There were resolved by removing foomatic and installing foomatic-db, foomatic-db-engine, foomatic-db-ppd instead.
Performing Utility Functions on Epson Printers
Here we explain how to perform some of the utility functions such as nozzle cleaning and nozzle checks on Epson printers. We will use the escputil utility, which is part of the gutenprint package.
There is a man page ("man escputil") that provides pretty good information, but it does not include necessary information on how to identify your printer. There are two parameters that can be used. One is --printer; what it expects is the name you used to identify your printer when you configured it. The other is --raw-device. What this option expects is is something beginning with "/dev". If your printer is a serial printer, and the only serial printer, it is "/dev/lp0". If it is an usb printer, it is "/dev/usb/lp0". If you have more than one printer, they will have names ending in "lp1", "lp2", etc.
- To clean the printer heads:
escputil -u --clean-head
- To prints the nozzle-check pattern, allowing you to verify that the previous head cleaning worked. (Or to determine that you need to clean the heads)
escputil -u --nozzle-check
If you want to perform an operation that requires 2-way communication with a printer, you must use the "--raw-device" specification, and your user must root or be a member of the group "lp".
- The following is an example of getting the printer's internal identification:
sudo escputil --raw-device=/dev/usb/lp0 --identify
- To prints out the ink levels of the printer:
sudo escputil --raw-device=/dev/usb/lp0 --ink-level
This is a printer status monitor which enables to get the remaining ink quantity, to print test patterns, to reset printer and to clean nozzle. It use an intuitive graphical user interface. Package can be downloaded from AUR.
Another Source for Printer Drivers
On http://www.turboprint.de/english.html is a really good printer driver for many printers not yet supported by Linux (especially Canon i*). The only problem is that high-quality-prints are either marked with a turboprint-logo or you have to pay for it... It's not Open-Source.
As a result of upgrade
Error with gnutls
After updating, if you get something like :
/usr/sbin/cupsd: error while loading shared libraries: libgnutls.so.13: cannot open shared object file: No such file or directory
You need to update gnutls:
pacman -S gnutls
In addition, in /etc/cups, there will be a file named cupsd.conf.pacnew. Rename it cupsd.conf.
All jobs are "stopped"
After updating CUPS, if all jobs sent to the printer become "stopped", delete the printer and add it again. Using the CUPS web interface (http://localhost:631), go to Printers > Delete Printer.
Note: If you don't remember your printer's settings, go to Printers > Modify Printer. Copy down the information displayed, click 'Modify Printer' to proceed to the next page(s), etc.
