Attached are notes on how to install HPLIP on the "pristine" Linux From
Scratch (LFS) build. This may indicate limitations of the present
package and how to overcome them. It may also answer queries on the use
of xscanimage.

Installing hplip-1.7.1 on an LFS/BLFS system
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This document describes the installation of hplip-1.7.1 on a Linux
from Scratch (LFS)/Beyond Linux from Scratch (BLFS) setup. We have
OfficeJet usb printers in mind. Printing and scanning was found to
work well on the HP-OfficeJet 5510 all-in-one.
Some system components of the LFS/BLFS build on which this experience
is based are: gcc-4.0.3; glibc-2.3.6; udev-088; Linux-2.6.16.5;
python-2.4.3; libusb-0.1.12; xfree86-4.5.0; gimp-2.2.10; cups-1.1.23;
ESP_Ghostscript-8.15.1; sane-1.0.17; foomatic-3.1.0.
The procedure installs hplip in a directory different from /usr or
/usr/local. If these standard locations are used, some of the
configuration steps may be omitted.
It is assumed that
(i) all the system requirements for the building of hplip are
met;
(ii) hplip-1.7.1.tar.gz has been untarred into a directory we
shall call "Build" and that the patch hplip-1.7.1-1.patch has
been copied to this directory. The contents of Build should look
like this: hplip-1.7.1/ hplip-1.7.1-1.patch;
(iii) you are now in Build.
Let's get to work. The various steps are described below.
First as an unprivileged user:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
$ cd hplip-1.7.1
$ patch -Np1 -i ../hplip-1.7.1-1.patch
$ sed -i "[EMAIL PROTECTED]@[EMAIL PROTECTED]" hplip.sh
$ ./configure --prefix=/usr/local/Hplip-1.7.1 \
--disable-network-build \
--disable-pp-build
$ make
Explanations:
^^^^^^^^^^^^
sed -i "[EMAIL PROTECTED]@[EMAIL PROTECTED]" hplip.sh is done to replace the
'daemon'
function in hplip.sh with 'pidofproc'. Lfs does not use 'daemon' at
all, but 'pidofproc' in stead.
--disable-network-build: if you do not have net-snmp installed.
--disable-pp-build: if your printers do not connect to the parallel
port.
Next, as root:
^^^^^^^^^^^^^
# export HPLIP_DIR="/usr/local/Hplip-1.7.1"
# mkdir -p $HPLIP_DIR/bin
# make install
Explanations:
^^^^^^^^^^^
You need to do the 'mkdir' bit because hplip will not create the 'bin'
directory and installation will fail as a result. If you install in
/usr/local or /usr this would not be a problem.
Now you need to configure for hplip (still as root):
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
# chmod 0744 $HPLIP_DIR/share/hplip/hplip
# cd /etc/rc.d/init.d
# ln -s $HPLIP_DIR/share/hplip/hplip hplip
# cd ../rc0.d
# ln -s ../init.d/hplip K01hplip
# cd ../rc3.d
# ln -s ../init.d/hplip S24hplip
# cd ../rc5.d
# ln -s ../init.d/hplip S24hplip
# cd ../rc6.d
# ln -s ../init.d/hplip K01hplip
# cd /usr/bin
# ln -s $HPLIP_DIR/bin/hpijs hpijs
# cd ../lib/sane
# ln -s $HPLIP_DIR/lib/libsane-hpaio.* .
Find the path in /dev to the printer. This is done by ls /dev and
looking for the usb/ directory, for example. Suppose the path is
/dev/usb/lp0
Edit /etc/profile and add the line
export SANE_DEFAULT_DEVICE="hpaio:/dev/usb/lp0"
Then run the command
# . /etc/profile
To /etc/ld.so.conf add the line
/usr/local/Hplip-1.7.1/lib
and run the command
# ldconfig
Finally,
# unset HPLIP_DIR
Explanations
^^^^^^^^^^^^
-- The 'hplip' binary as installed is not executable, hence the
"chmod" step.
-- The lfs-setup has 'init.d' in a place different from what the
installation procedure expects. We have to make a symlink in 'init.d'
to where 'hplip' is.
-- The symlinks set up in the rc.{0,1,3,5,6} directories will activate
the two hplip daemons at boot time and bring them down at shutdown
time. It is important to note that these daemons must be activated
before the 'cups' daemon and shut down after the 'cups' daemon. Thus
the numbers 'xy' in the 'Sxy' links must preceed those for 'cups'. The
'xy' in 'Kxy' must be larger than those for cups. So have a good look
at what goes on in the 'rc.n' directories.
-- It is important to have a link in /usr/bin to the 'hpijs' binary.
Without this link 'cups' will get lost. That is one reason why
installation of 'hplip' in /usr is recommended.
-- Sane will look for the 'libsane-hpaio' libraries in /usr/lib/sane.
So we have to establish a link. Without these links scanning at least
with 'xscanimage' will not work. The final dot in the command line
should not be left out.
-- The environment variable SANE_DEFAULT_DEVICE will make 'xscanimage'
work from wherever it is called. This really is a nice thing to do!
-- Having 'ldconfig' make the hplip libraries visible to the system
may be of importance to software that leans on hplip.
You may now follow the hplip documentation to set up the program, but do
it from a freshly called X-term so that SANE_DEFAULT_DEVICE can be seen.
If you set the variable SANE_DEFAULT_DEVICE do not give a command to
xscanimage when you configure.
Hopefully this is of value to users of other Linux distributions as
well.
