%general-entities; ]> $Date$ Cups The Common Unix Printing System (CUPS) is a print spooler and associated utilities. It is based on the "Internet Printing Protocol" and provides printing services to most PostScript and raster printers. &lfs110a_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &cups-md5sum; Download size: &cups-size; Estimated disk space required: &cups-buildsize; Estimated build time: &cups-time; Cups Dependencies Required Recommended , , , , and Optional , , (with clang), , , , and Required (Postinstall) Optional (Postinstall) and hplip (HP printers) User Notes: There used to be a conflict between the Cups libusb backend and the usblp kernel driver. This is no longer the case and cups will work with both of these enabled. If you want to use the kernel usblp driver (for example, if you wish to use escputil from ) enable the following options in your kernel configuration and recompile the kernel: Device Drivers ---> [*] USB support ---> [CONFIG_USB_SUPPORT] <*/M> OHCI HCD (USB 1.1) support [CONFIG_USB_OHCI_HCD] <*/M> UHCI HCD (most Intel and VIA) support [CONFIG_USB_UHCI_HCD] <*/M> USB Printer support [CONFIG_USB_PRINTER] If you have a parallel printer, enable the following options in your kernel configuration and recompile the kernel: Device Drivers ---> <*/M> Parallel port support ---> [CONFIG_PARPORT] <*/M> PC-style hardware [CONFIG_PARPORT_PC] Character devices ---> <*/M> Parallel printer support [CONFIG_PRINTER] cups You will need to add an lp user, as Cups will create some files owned by this user. (The lp user is the default used by Cups, but may be changed to a different user by passing a parameter to the configure script.) Use the following command as the root user: useradd -c "Print Service User" -d /var/spool/cups -g lp -s /bin/false -u 9 lp You will also need a dedicated group that will contain users allowed to do Cups administrative tasks. Add the group by running the following command as the root user: groupadd -g 19 lpadmin If you want to add a user to the Cups administrative group, run the following command as the root user: usermod -a -G lpadmin <username> If you didn't install , use the following sed to change the default browser that will be used to access the Cups web interface: sed -i 's#@CUPS_HTMLVIEW@#firefox#' desktop/cups.desktop.in Replace firefox with the web browser of your choice. Upstream perfers clang than gcc, but the building system will try to use a compiler warning option unsupported by clang. If clang is installed, remove this warning option: sed -e "s/-Wno-format-truncation//" \ -i configure \ -i config-scripts/cups-compiler.m4 Build Cups by running the following commands: ./configure --libdir=/usr/lib \ --disable-systemd \ --with-rcdir=/tmp/cupsinit \ --with-system-groups=lpadmin \ --with-docdir=/usr/share/cups/doc-&cups-version; && make ./configure --libdir=/usr/lib \ --with-system-groups=lpadmin \ --with-docdir=/usr/share/cups/doc-&cups-version; && make To test the results, issue: LC_ALL=C make -k check. An already active graphical session with bus address is necessary to run the tests. Make sure that there is not other instance of Cups running, otherwise at least 4 tests will fail with "address in use". Now, as the root user: make install && ln -svnf ../cups/doc-&cups-version; /usr/share/doc/cups-&cups-version; Remove the shipped bootscript, which is incompatible with LFS: rm -rf /tmp/cupsinit && Create a basic Cups client configuration file by running the following command as the root user: echo "ServerName /run/cups/cups.sock" > /etc/cups/client.conf sed ... configure: This sed removes a compiler option which is no longer supported. Leaving this change out, the compilation will run thru but a warning about an invalid warning option will be emitted on every compiler invocation. CC=gcc CXX=g++: Setting them if you prefer to use gcc instead of clang, which is now preferred by the upstream. --disable-systemd: Systemd is not supported by this version of BLFS. --with-rcdir=/tmp/cupsinit: This switch tells the build process to install the shipped bootscript into /tmp instead of /etc/rc.d. --with-system-groups=lpadmin: This switch ensures that only lpadmin will be used as the Cups administrative group. --disable-libusb: Use this switch if you have installed , but wish to use the kernel usblp driver. --enable-libpaper: Use this switch if you have installed libpaper and wish to use it with Cups. /etc/cups/* /etc/cups/* Normally, printers are set up via a web browser. The Cups server will normally connect via the url http://localhost:631. From there printers, print jobs, and the server configuration can be set up and managed. Remote system administration can also be set up. Configuration can also be done from the command line via the lpadmin, lpoptions, and lpstat commands. Configuration of Cups is dependent on the type of printer and can be complex. Generally, PostScript printers are easier. For detailed instructions on configuration and use of Cups, see . For non-PostScript printers to print with Cups, you need to install to convert PostScript to raster images and a driver (e.g. from ) to convert the resulting raster images to a form that the printer understands. Foomatic drivers use to convert PostScript to a printable form directly, but this is considered suboptimal by Cups developers. If CUPS has been built with Linux PAM support, you need to create a PAM configuration file to get it working correctly with BLFS. Issue the following command as the root user to create the configuration file for Linux PAM: cat > /etc/pam.d/cups << "EOF" # Begin /etc/pam.d/cups auth include system-auth account include system-account session include system-session # End /etc/pam.d/cups EOF If you want the Cups print service to start automatically when the system is booted, install the init script included in the package: To start the cupsd daemon when something tries to access it, enable the previously installed systemd units by running the following command as the root user: cups make install-cups systemctl enable cups Installed Programs Installed Libraries Installed Directories cancel, cupsaccept, cups-config, cupsctl, cupsd, cupsdisable, cupsenable, cupsfilter, cupsreject, cupstestppd, ippeveprinter, ipptool, lp, lpadmin, lpc, lpinfo, lpmove, lpoptions, lpq, lpr, lprm, lpstat, ppdc, ppdhtml, ppdi, ppdmerge, and ppdpo libcupsimage.so and libcups.so /etc/cups, /usr/{include,lib,share}/cups, /usr/share/doc/cups-&cups-version;, and /var/{cache,log,run,spool}/cups Short Descriptions cancel cancels existing print jobs from the print queues cancel cupsaccept accept jobs sent to a destination cupsaccept cups-config is a Cups program configuration utility cups-config cupsctl updates or queries the cupsd.conf file for a server cupsctl cupsd is the scheduler for the Common Unix Printing System cupsd cupsdisable stop printers and classes cupsdisable cupsenable start printers and classes cupsenable cupsfilter is a front-end to the Cups filter subsystem which allows you to convert a file to a specific format cupsfilter cupsreject reject jobs sent to a destination cupsreject cupstestppd tests the conformance of PPD files cupstestppd ippeveprinter is an IPP Everywhere printer for CUPS ippeveprinter ipptool sends IPP requests to the specified URI and tests and/or displays the results ipptool lp submits files for printing or alters a pending job lp lpadmin configures printer and class queues provided by Cups lpadmin lpc provides limited control over printer and class queues provided by Cups lpc lpinfo lists the available devices or drivers known to the Cups server lpinfo lpmove moves the specified job to a new destination lpmove lpoptions displays or sets printer options and defaults lpoptions lpq shows the current print queue status on the named printer lpq lpr submits files for printing lpr lprm cancels print jobs that have been queued for printing lprm lpstat displays status information about the current classes, jobs, and printers lpstat ppdc compiles PPDC source files into one or more PPD files ppdc ppdhtml reads a driver information file and produces a HTML summary page that lists all of the drivers in a file and the supported options ppdhtml ppdi imports one or more PPD files into a PPD compiler source file ppdi ppdmerge merges two or more PPD files into a single, multi-language PPD file ppdmerge ppdpo extracts UI strings from PPDC source files and updates either a GNU gettext or Mac OS X strings format message catalog source file for translation ppdpo libcups.so contains the Cups API functions libcups.so
