Lexmark X1190 with Ubuntu 11.10 (64 bits)

I have installed this printer for a number of Ubuntu distributions, and I always forget to write the details, so here they go:

Printer (mostly from http://blog.rachaelbond.com/lexmark/)

1. With synaptic, install ia32-libs, libstdc++5:i386 and rpm
2. Download  CJLZ600LE-CUPS-1.0-1.TAR.gz, for example from: software.rachaelbond.com/CJLZ600LE-CUPS-1.0-1.TAR.gz
3. tar xzvf CJLZ600LE-CUPS-1.0-1.TAR.gz
4. tail -n +143 z600cups-1.0-1.gz.sh > install.tar.gz
5. tar xzvf install.tar.gz
6. sudo rpm --force-debian -ivh z600cups-1.0-1.i386.rpm z600llpddk-2.0-1.i386.rpm --nodeps
7. sudo service cups restart
8. configure printer from the system settings with driver Lexmark-Z600

 Scanner

1. I get rid of libsane and libsane-extras
2. I follow more or less the instructions by Ashley Hooper at: https://bugs.launchpad.net/ubuntu/+source/xsane/+bug/774475
3. Instead of the 386 packages, I install the amd64 ones: http://ftp.us.debian.org/debian/pool/main/s/sane-backends-extras/libsane-extras_1.0.21.2_amd64.deb and http://ftp.us.debian.org/debian/pool/main/s/sane-backends/libsane_1.0.21-9_amd64.deb
4. In order to avoid upgrading these by mistake, I fix them:
   gksudo gedit /etc/apt/preferences.d/libsane
   Now paste the below contents into the file, save and exit.
   
   Package: libsane
   Pin: version 1.0.21-9
   Pin-Priority: 900
5. I confirm it is working using the apt-cache policy command: $ apt-cache policy libsane
6. Now either simple-scan or xsane work nicely with the scanner.
