CUPS网站的介绍: "The Common UNIX Printing System ("CUPS")CUPS 是个跨UNIX平台的打印解决方案. 它基于“网络打印协议”并且为大多数Postscript和光栅打印机提供完整的打印服务。CUPS基于GUN GPL协议提供。”虽然有其他的打印程序包例如LPRNG，但CUPS是相当流行和相对容易使用的。它是Arch linux及许多其他Linux发行版缺省的打印系统。 It is based on the "Internet Printing Protocol" and provides complete printing services to most Postscript and raster printers. CUPS is provided under the GNU GPL..." Although there are other printing packages such as LPRNG, CUPS is quite popular and relatively easy to use. It is the default printing system on Arch Linux as well as many other Linux distributions.
Troubleshooting CUPS & components CUPS及组件的疑难解答
The best way to get printing working is to set 'LogLevel' in '/etc/cups/cupsd.conf' to:在‘/etc/cups/cupsd.conf’文件中设置‘LogLevel’是让打印机工作最好的方法：
And then viewing the output from '/var/log/cups/error_log' like this:
tail -n 100 -f /var/log/cups/error_log
The characters at the left of the output stands for:
D = Debug E = Error I = Information etc...
These files may also prove useful.
/var/log/cups/page_log 'spits out a new entry each time a print is successful.' /var/log/cups/access_log 'lists all cupsd http1.1 server activity'
Of course it's important to know how CUPS work if you want to solve your problems, this is somewhat correct:
- An application sends a .ps file(PostScript, a script language that details how the page will look) to CUPS when you select 'print'(99% of apps do).
- CUPS then looks at your printers PPD file(printer description file) and figures out what filters it needs to use to convert the .ps file to a language that the printer understands(like PJL,PCL). Usually it needs ghostscript.
- GhostScript takes the input and figures out which filters it should use,then applies them and converts the .ps file to a format understood by the printer.
- Then it is sent to the backend. For example, if you have your printer connected to a USB port, it uses the USB backend.
Print a document and watch 'error_log' to get a more detailed and correct image of the printing process.
You will need CUPS and Ghostscript for sure:
# pacman -S cups ghostscript gsfonts
- cups - The actual CUPS software
- ghostscript - An interpreter for the Postscript language
- gsfonts - Ghostscript standard Type1 fonts
- gutenprint - A collection of high quality drivers for Canon, Epson, Lexmark, Sony, Olympus, and PCL printers for use with Ghostscript, CUPS, Foomatic, and the Gimp.
- foomatic, foomatic-db, foomatic-db-engine, foomatic-db-ppd and foomatic-filters - Foomatic is a database-driven system for integrating free software printer drivers with common spoolers under Unix
- Installing foomatic-filters should solve your problems if the cups error.log is reporting "stopped with status 22!"
- hplip - HP Linux inkjet driver. Provides support for DeskJet, OfficeJet, Photosmart, Business Inkjet and some LaserJet printer models.
- cups-pdf - A nice package that allows one to setup a virtual PDF Printer that generates a PDF out of anything sent to it.
如果是使用网络打印机If your system is connected to a networked printer using the samba protocol or if the system is to be a print server for Windows clients:
# pacman -S samba
Download Printer PPD
Depending on your printer, this step is optional and may not be needed as the standard CUPS installation already comes with quite a few PPD (Postscript Printer Description) files. Moreover, the foomatic-filters, gimp-print and hplip packages already include quite a few PPD files which will automatically be detected by CUPS.
Here's an explanation of what a PPD file is from the Linux Printing website: "For every PostScript printer the manufacturers provide a PPD file which contains all printer-specific information about the particular printer model: Basic printer capabilities as whether the printer is a color printer, fonts, PostScript level, etc., and especially the user-adjustable options, as paper size, resolution, etc."
- To get the PPD file for your printer, go to http://www.linuxprinting.org/printer_list.cgi and select the manufacturer and model of your printer.
- Now, you will need to copy the file to the cups folder so it can detect the file. If you are in the folder where you downloaded the PPD file, you can use the following command:
# cp your_printer.ppd /usr/share/cups/model/
If you cannot find your printer on the website, you may want to try similar models or using generic printer drivers. Just do some googling or ask your manufacturer (good luck with that...).
Now that you have cups installed, you have a variety of options on how to setup CUPS. You can always use the tried and true command line. Likewise, various desktop environments such as Gnome and KDE have useful programs that can help you manage your printers. However, in order to make this process easy for the largest amount of users, we will use the web interface provided by CUPS.
Please note that if you are planning on connecting to a network printer, rather than one that is directly connected to your computer, you may wish to jump to the Printer Sharing section first. Linux to Linux printer sharing is quite easy and involves very little configuration. Windows to Linux and vice-versa requires a little bit more effort, but is relatively easy as well.
Before we can use the CUPS web interface, we must install the appropriate kernel modules. The following are steps that I got from the Gentoo Printing Guide.
If you want to use a USB printer with a 2.6.x kernel, use the following command:
# modprobe usblp
If you are using a USB printer and a 2.4.x kernel, use the following command:
# modprobe printer
Note, this assumes that you are using the stock kernels from Arch Linux. If you custom-rolled your own, you may need to run this first:
# modprobe usbcore
Once you have the modules installed, you should plug in your printer and check if the kernel detected it by running the following:
# tail /var/log/messages.log
You should see something like this:
Feb 19 20:17:11 kernel: printer.c: usblp0: USB Bidirectional printer dev 2 if 0 alt 0 proto 2 vid 0x04E8 pid 0x300E Feb 19 20:17:11 kernel: usb.c: usblp driver claimed interface cfef3920 Feb 19 20:17:11 kernel: printer.c: v0.13: USB Printer Device Class driver
Parallel port printers
If you plan on using a parallel port printer, the configuration is pretty much the same. Kernel 2.6.x users have to first type in:
# modprobe lp
And then both 2.4.x and 2.6.x kernel users can enter in:
# modprobe parport # modprobe parport_pc
Once again, you can check your setup by running:
# tail /var/log/messages.log
You should see something like this:
# lp0: using parport0 (polling).
Note: Installing my Brother HL 1250 i found that permissions for the device don't let cups to write on the device, so practically it doesn't print. To fix it:
[root@mihal usb]# cd /dev/usb/ [root@mihal usb]# ls lp0 [root@mihal usb]# chgrp lp lp0
You may also want to have the system automatically load the kernel module every time the computer starts up. To do this use your favorite text editor to open up
/etc/rc.conf and add the appropriate module to the MODULES=() line. Here's a portion of the text from my
MODULES=(!usbserial scsi_mod sd_mod snd-ymfpci snd-pcm-oss lp parport parport_pc ide-scsi)
With the kernel modules installed, you are now ready to start the actual CUPS daemon. To do this, simply run this command:
# /etc/rc.d/cups start
If you want to have cups start up automatically every time you start your computer, than you need to add it to your DAEMONS=() line in the /etc/rc.conf file. For example:
# DAEMONS=(pcmcia syslogd klogd !fam esd mono network autofs cups crond gdm)
Web Interface and tool kit.
Once the daemon is running, if a web interface is available. Open up your browser and go to:
(可能需要把 localhost'替换为你的主机名——可以在文件 /etc/hosts'里面看到')
or install "Gnome Cups Manager" GUI frontend (see Appendix: A.1 Alternative CUPS Interfaces)
From here, all you have to do is follow the various wizards to add your printer. To setup my Samsung ML-1250 printer, I started out by click on Manage Printers, and then Add Printer. I was then prompted for a username and password. I just logged in as root. I entered in ml1250 for my printer name, My Room for location and then Peter's Samsung ML-1250 Laster Printer for description. Next you will select the device. Since my printer is a USB device, I just selected USB Printer #1. The name of my printer also showed up next to the label USB Printer #1, so look for that. Next, I simply chose the appropriate drivers and the installation was complete.
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":
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/cups 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 Factory: I did not have to do this step with cups 1.3.7. Going to localhost:631 on the client and then manage printers works fine without ever creating this file.:
Next, run the following command to update the client computerFactory: Same as the previous step... I did not have to do this.:
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). Factory: This link brings the user to a "404 Not Found" page.
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 共享给 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 共享给 Linux
有时，我们需要允许一台装windows系统的电脑连接到一台linux电脑上.方法有很多种，最常用的就是使用Samba.编辑samba配置文件 /etc/samba/smb.conf ，使其允许控制打印机。修改后的smb.conf 看起来如下:
[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
[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
A Pygtk CUPS configuration program from Red Hat is also available in the "community" repository:
pacman -S system-config-printer
You can also try hal-cups-utils, also from community:
pacman -S hal-cups-utils
KDE users can modify their printers from the Control Center. Refer the KDE documentation for more information on how to use the interface.
There is also gtklp for handling print jobs. It is in the "extra" repository.
pacman -S gtklp
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 pnm2ppa can be found in 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 -Sy 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.
