%general-entities; ]> $LastChangedBy$ $Date$ 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. &lfs75_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; Additional Downloads Required patch: Required patch: Optional patch: Cups Dependencies Recommended and Optional (if you have it installed, then is required) or , libpaper, , , , , , and Required (Runtime) 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 ---> OHCI HCD (USB 1.1) support: Y or M UHCI HCD (most Intel and VIA) support: Y or M USB Printer support: Y or M If you have a parallel printer, enable the following options in your kernel configuration and recompile the kernel: Device Drivers ---> Parallel port support ---> PC-style hardware: Y or M Character devices ---> Parallel printer support: Y or M 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. If you need to access a remote Cups print server, use the following patch: patch -Np1 -i ../cups-&cups-version;-content_type-1.patch Install Cups by running the following commands: patch -Np1 -i ../cups-&cups-version;-blfs-1.patch && patch -Np1 -i ../cups-&cups-version;-avahi_optional-1.patch && aclocal -I config-scripts && autoconf -I config-scripts && CC=gcc \ ./configure --libdir=/usr/lib \ --with-rcdir=/tmp/cupsinit \ --with-docdir=/usr/share/cups/doc \ --with-system-groups=lpadmin && make To test the results, issue: make -k check. An already active graphical session with bus address is necessary to run the tests. A small number of tests fail for unknown reasons. Now, as the root user: make install && rm -rf /tmp/cupsinit && ln -svfn ../cups/doc /usr/share/doc/cups-&cups-version; Create a basic Cups client configuration file by running the following command as the root user: echo "ServerName /var/run/cups/cups.sock" > /etc/cups/client.conf Remove filters that are now part of the Cups Filters package by running the following commands as the root user: rm -rf /usr/share/cups/banners && rm -rf /usr/share/cups/data/testprint If you reinstall or update Cups, commands above break , which needs, therefore, to be reinstalled. CC=gcc: This environment variable ensures that gcc is used if clang is installed. The build fails with the clang compiler. --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. --disable-gnutls --enable-openssl: This switch tells the build process to use instead of . The current version of GnuTLS might produce lot of warnings during the Cups build. /etc/cups/* /etc/cups/* 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 . The Software Administrators Manual and Software Users Manual are particularly useful. 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 Ghostscript to convert PostScript to a printable form directly, but this is considered to be a hack by Cups developers. If you want the Cups print service to start automatically when the system is booted, install the init script included in the package: cups make install-cups Installed Programs Installed Libraries Installed Directories accept, cancel, cupsaccept, cupsaddsmb, cups-config, cupsctl, cupsd, cupsdisable, cupsenable, cupsfilter, cupsreject, cupstestdsc, cupstestppd, ippfind, ipptool, lp, lpadmin, lpc, lpinfo, lpmove, lpoptions, lppasswd, lpq, lpr, lprm, lpstat, ppdc, ppdhtml, ppdi, ppdmerge, ppdpo and reject libcupscgi.so, libcupsimage.so, libcupsmime.so, libcupsppdc.so and libcups.so /etc/cups, /usr/include/cups, /usr/lib/cups, /usr/share/cups, /usr/share/doc/cups-&cups-version;, /var/cache/cups, /var/log/cups, /var/run/cups and /var/spool/cups Short Descriptions accept instructs the printing system to accept print jobs to the specified destinations. accept cancel cancels existing print jobs from the print queues. cancel cupsaddsmb exports printers to the Samba software for use with Windows clients. cupsaddsmb 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 cupsfilter is a front-end to the Cups filter subsystem which allows you to convert a file to a specific format. cupsfilter cupstestdsc tests the conformance of PostScript files. cupstestdsc cupstestppd tests the conformance of PPD files. cupstestppd ippfind finds internet printing protocol printers. ippfind 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 lppasswd adds, changes or deletes passwords in the Cups digest password file passwd.md5. lppasswd 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 reject instructs the printing system to reject print jobs to the specified destinations. reject libcups.so contains the Cups API functions. libcups.so
