Install Linux Canon Printer Driver in Ubuntu

https://help.ubuntu.com/community/CanonCaptDrv190


Canon provide Debian Packages to install the driver under ubuntu for download. Offical supported is only the previous version 10.04 of ubuntu. Extracting the zip file you will find under
/32-bit_Driver/Debian
the deb packages. First thing to install is cndrvcups-common_2.20-l_i386.deb with dpkg -i . The problem is that ubuntu 11.04 doesn’t contain the required gs-esp package.
Workaround is to download and install it with
dpgk -i gs-esp_9.01~dfsg~svn12047-0ubuntu1_all.deb
After that you can install the common canon driver and afterwards the ufr driver:
dpgk -i cndrvcups-common_2.20-1_i386.deb dpgk -i cndrvcups-ufr2-uk_2.20-1_i386.deb
Now you can open the driver setup application and click on the add button. Choose network printer, enter the ip of your canon printer and click on examine. Select from the list below Canon and click on next. Select “LBP6650″ and click on next. Confirm dialog with use button. Test your configuration with printing a test page.

How to enable the root account in Ubuntu

Ubuntu is one of the few Linux distributions out there that will not enable the root account.In case you want to enable root login on your Ubuntu system this post will show you how you can do that.

As you have noticed during the Ubuntu installation there was no question about the root password,as you might have been used to see during other Linux distributioninstallation process. This is why the root account is inactive andcan’t be used (no password configured) until we will setup a properpassword for it. To do this, we simply need to run:

sudo passwd root

This will ask for a new root password and once you confirm it, you can start using the root account to login.

In case you will want tdisable back the root account, just lock the root account by running:

sudo passwd -l root

Are you aware of any other Linux distribution that doesn’t enablethe root account at installation time? I am just curious because Ibelieve that this is a great idea… but I haven’t seen it implemented inother distributions.

Howto mount partition onto ubuntu Linux

Q. How do I mount NTFS or FAT paritions under ubuntu Linux?

A. You can mount NTFS or FAT windows partition with mount command.

=> Click on Applications
=> Select Accessories
=> Select Terminal
=> Now terminal window will be on screen.

First you need to create directory where you can attach windows partition using mount command (for example /media/c for C:):# sudo mkdir -p /media/cNow find out list of partition (click on System > Administration > Disks ) or use following command:# sudo fdisk -l

Output:

Device Boot Start End Blocks Id System
/dev/hdb1 * 1 2432 19535008+ 86 NTFS
/dev/hdb2 2433 2554 979965 82 Linux swap / Solaris
/dev/hdb3 2555 6202 29302560 83 Linux

As you see /dev/hdb1 is NTFS partition. Now type following command:# sudo mount -t ntfs -o nls=utf8,umask=0222 /dev/hdb1 /media/cTo unmount Windows NTFS partition type command:# sudo umount /media/cTo mount FAT partition type command:# sudo mkdir -p /media/d
# sudo mount -t vfat -o iocharset=utf8,umask=000 /dev/hda1 /media/d

To unmount Windows FAT (mounted at /media/d) partition type command:# sudo umount /media/d

Where,

-t : Specify file system type (such as NTFS or FAT)
umask=VALUE: Set the umask (the bitmask of the permissions that are not present). The default is the umask of the current process. The value is given in octal.
iocharset=VALUE: Character set to use for converting between 8 bit characters and 16 bit Unicode characters. The default is iso8859-1. Long filenames are stored on disk in Unicode format.
