TITLE: Printing on LFS LFS VERSION: any AUTHOR: Wolfgang Arendt SYNOPSIS: This hint describes, how to set up basic printing. We are assuming local networking is enabled, sections 9.1 through 9.6 of the book. HINT: Table of contents * Introduction * About this hint * Packages * Prerequisites * Hardware * Kernel * Users and groups: * apsfilter * Building gdbm * Building LPRng * Building Ghostscript * Building psutils * Installing a2ps * Building apsfilter * Sources and disclaimer Introduction We will build LPRng with gdbm support. It will run as user lp, member of the daemon group. In this example, the GID of the group daemon is 5 and so is the UID of the user lp. Please modify all commands to fit your environment. All components will install their configuration into the /etc directory. Moreover we will install Ghostscript as printer driver, assisted by a2ps, the "any to Postscript" converter, apsfilter and psutils. About this hint This hint is a merge of the following documents: printing.txt by Fabio Fracassi print.txt by ktb ghostscript.txt by Wolfgang Arendt printing2.txt by Wolfgang Arendt Packages The basic printing system consists of the following packages: gdbm-1.8.0.tar.gz ftp://ftp.gnu.org/gnu/gdbm/ LPRng-3.8.4.tgz ftp://ftp.lprng.com/pub/LPRng/LPRng/ psutils-p17.tar.gz ftp://ftp.dcs.ed.ac.uk/pub/ajcd/ a2ps-4.13:a2ps-4.13 ftp://ftp.enst.fr/pub/unix/a2ps/ apsfilter-7.1.1.tar.gz http://www.apsfilter.org/download/ ghostscript-7.00.tar.gz http://download.sourceforge.net/ghostscript/ Prerequisites Hardware You need a supported printer. Check: http://www.linuxprinting.org/printer_list.cgi for a list of supported hardware. Kernel You need a kernel with support for the interface, your printer is connected to and printing support in general. To check, whether this is the case, try the following: For a local printer on the first parallel port try: echo > /dev/lp0 The printer should react in any way. For a networked printer try pinging the IP number of the printer. If one of those worked, you are ready to install the software. If the printer did not respond make sure it is connected to the computer correctly i.e., check cables, make sure the network is working correctly and that there is kernel support for the printer. You can check, whether your kernel supports the parallel port, by running cat /usr/src/linux/.config | grep CONFIG_PARPORT You can check, whether you have printing support in the kernel, by running: cat /usr/src/linux/.config | grep CONFIG_PRINTER Users and groups: The printer daemon should not run as user root for security reasons. Check, whether you have a user named "lp", that is member of the group "daemon". If you do not, create such user, by running groupadd -g 5 daemon useradd -u 5 -d /var/spool/lp -s /bin/sh -g daemon lp apsfilter In order to build apsfilter, it is necessary, that you have an executable file named "sendmail" in your path. This does not need to be a real mail transfer agent, since apsfilter does not really use it, except for acquiring the apsfilter's author's mail address. You might get along, by creating a faked sendmail, like touch /usr/bin/sendmail && chmod 750 /usr/bin/sendmail but consider installing a real MTA. If you want an easy solution for a dial-up system, consider Masqmail, which is quite easy to set up. Find Masqmail here: http://www.innominate.org/~oku/masqmail/ (please consider, sending the apsfilter's author an email nevertheless). Building gdbm The gdbm database library helps speed up large print jobs. LPRng does not compile unless you have "gdbm" installed. You may choose, not to install it, and to skip this section. In that case, you will have to use "--disable-gdbm" as a "configure" option, when compiling LPRng. For more information see: * http://www.astart.com/lprng/LPRng-HOWTO.html * http://www.gnu.org/software/gdbm/gdbm.html The configure script does not seem to recognize the "--prefix=..." option correctly, so we will manually make an adjustment to the Makefile. Enter: ./configure && ed Makefile <), then copy it there from the src subdirectory. Stay in the same directory and extract the zlib-package. This creates a directory named zlib-1.1.3. Rename this directory to zlib (or make a symlink). Extract jpegsrc.v6b.tar.gz and rename the jpeg-6b directory to jpeg (or make a symlink). Extract libpng-1.2.1.tar.gz and move the libpng-1.2.1-directory to libpng (or - guess, what - make a symlink). Create the file changes.sed, containing the following lines: s|XINCLUDE=-I/usr/local/X/include|XINCLUDE=-I/usr/X11R6/include| s|XLIBDIRS=-L/usr/X11/lib|XLIBDIRS=-L/usr/X11R6/lib| s|jpeg-6a|jpeg| s|prefix = /usr/local|prefix = /usr| w Makefile Now create the Makefile, by running the following command: sed -n -f changes.sed unix-gcc.mak Now, you should be ready to compile the whole thing. Just run: make && make install If the compilation fails with error messages, containing something about zdevcal.c, then append the line #include to the file src/time_.h and try again. (This might have to do with glibc-2.2.... but I am not sure about it). Finally extract the fonts to the /usr/share/ghostscript directory. The directory structure should look somewhat like this: /usr/share/ghostscript /usr/share/ghostscript/7.00 /usr/share/ghostscript/fonts Notes: If you have zlib and libpng installed, you might choose, to use shared versions of the libpng and zlib libraries. In that case, please edit the Makefile, before running "make": Change SHARE_LIBPNG=0 to SHARE_LIBPNG=1. Change SHARE_ZLIB=0 to SHARE_ZLIB=1. Make sure you have the paths to your X libs and X*.h files accessible to the build process. With a default X install they should be in /usr/X11R6/lib and /usr/X11R6/include/X11. Make sure, that the following two lines to are in your /etc/ld.so.conf: /usr/X11R6/lib /usr/X11R6/include/X11 and run ldconfig It is possible, to build ghostscript, without having X installed. In that case, edit the Makefile and comment out all the lines, that refer to X. Building psutils Installing psutils is optional. If you do not install the package, you will get a warning, when you install a2ps. For more information see: http://www.dcs.ed.ac.uk/home/ajcd/psutils/ The following command will install psutils. It is configured for paper size a4. If you need another media type, then you need to change the line beginning with PAPER= in the Makefile. cp Makefile.unix Makefile && ed Makefile <
