%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. 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 Recommended , , and Optional , , , or GnuTLS (which needs libgpg-error, libgcrypt and opencdk, in that order), , , , , OpenSLP, libpaper, libacl (requires libattr), HTMLDOC, and Valgrind (optionally used if running the test suites) User Notes: Create 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 /dev/null -g lp -s /bin/false -u 9 lp Install CUPS by running the following commands: ./configure && make To test the results, issue: make check. This will run a basic test suite without any load testing. If you wish to run the tests specifying non-default parameters, issue: make test. Note that the torture load testing test uses more resources than those displayed in the prompt. Now, as the root user: make install The man files are installed in compressed (.gz) format. If desired, use the following commands to uncompress them: gunzip -v /usr/share/man/man{\ 1/{cancel,cups{-config,test{dsc,ppd}},\ lp{,options,passwd,q,rm,r,stat}}.1,\ 5/{{classes,client,cups-snmp,cupsd,printers,subscriptions,mailto}.conf,\ mime.{convs,types}}.5,\ 7/{backend,filter}.7,\ 8/{accept,cups{d,addsmb,enable,-{deviced,driverd,lpd,polld,}},\ lp{admin,info,move,c}}.8}.gz && rm -v /usr/share/man/man8/{reject,cupsdisable}.8.gz && ln -v -s accept.8 /usr/share/man/man8/reject.8 && ln -v -s cupsenable.8 /usr/share/man/man8/cupsdisable.8 The basic default behavior of the installation is appropriate for LFS systems. CUPS files are placed in /usr/bin, /usr/sbin, /var and /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. During the installation, CUPS added startup files in /etc/rc.d. These scripts will work in most cases, but will fail if you provide printers to Samba clients. Additionally, they are not consistent with standard LFS style scripts. Replace the installed scripts with the scripts and symlinks included in the package: cups make install-cups Installed Programs Installed Libraries Installed Directories accept, cancel, cups-config, cupsaddsmb, cupsd, cupstestppd, disable, enable, lp, lpadmin, lpc, lpinfo, lpmove, lpoptions, lppasswd, lpq, lpr, lprm, lpstat, and reject libcups.{so,a}, libcupsimage.{so,a}, and various filters and backend drivers /etc/cups, /usr/include/cups, /usr/lib/cups, /usr/share/doc/cups, /usr/share/cups, /var/log/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 cups-config is a CUPS program configuration utility. cups-config cupsaddsmb exports printers to the Samba software for use with Windows clients. cupsaddsmb cupsd is the scheduler for the Common Unix Printing System. cupsd cupstestppd tests the conformance of PPD files. cupstestppd disable stops the named printers or classes. disable enable starts the named printers or classes. enable 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 reject instructs the printing system to reject print jobs to the specified destinations. reject
