Cups-2.3.3
Kernel Configuration
![[Note]](../images/note.png)
Note
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
Gutenprint-5.3.3) 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]
Installation of 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 xdg-utils-1.1.3, 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.
Build Cups by running the
following commands:
sed -i '/stat.h/a #include <asm-generic/ioctls.h>' tools/ipptool.c &&
CC=gcc CXX=g++ \
./configure --libdir=/usr/lib \
--disable-systemd \
--with-rcdir=/tmp/cupsinit \
--with-system-groups=lpadmin \
--with-docdir=/usr/share/cups/doc-2.3.3 &&
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.
Now, as the root user:
make install &&
rm -rf /tmp/cupsinit &&
ln -svnf ../cups/doc-2.3.3 /usr/share/doc/cups-2.3.3
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
Note
This package installs icon files into the /usr/share/icons/hicolor hierarchy and you can
improve system performance and memory usage by updating
/usr/share/icons/hicolor/index.theme. To
perform the update you must have GTK+-2.24.33 or
GTK+-3.24.25 installed and issue the following
command as the root user:
gtk-update-icon-cache -qtf /usr/share/icons/hicolor
Command Explanations
sed ...
tools/ipptool.c: This sed fixes a bug caused by
glibc-2.30 changing the user-space API for sockets.
CC=gcc CXX=g++: This environment
variable ensures that gcc is used, if clang is installed. Remove
it, if you prefer to use clang. Using clang almost doubles build
time and slightly decreases build disk space. Installed disk space
is not appreciably modified.
--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 libusb-1.0.24, 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.
Configuring Cups
Configuration Information
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 http://www.cups.org/documentation.php.
For non-PostScript printers to print with Cups, you need to install ghostscript-9.53.3
to convert PostScript to raster images and a driver (e.g. from
Gutenprint-5.3.3) to convert the resulting
raster images to a form that the printer understands.
Foomatic drivers use ghostscript-9.53.3 to convert PostScript
to a printable form directly, but this is considered suboptimal
by Cups developers.
Linux PAM
Configuration
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
Boot
Script
If you want the Cups print
service to start automatically when the system is booted, install
the init script included in the blfs-bootscripts-20210110 package:
make install-cups
