Writing in Indian Launguages in Linux using IBus

To compose a document other than in English you need transliteration software. In Linux there is one such software that is IBus.Through IBus you can write in any language with ease. 

Installation

 In Debian start the synaptic package manager click the search button  and type IBus in the search field and press enter.

Synaptic Package Manager

 Now scroll down and select IBus it will show the dependencies of the packages click ok and again the same with IBus-m17n and click apply in the taskbar. Make sure you have m17n-db package is installed before installing IBus.  

Location & Usage

After installation configure your system to make IBus starts when you login.IBus is typically located in your systray. It will show as EN.

This is your default locale setting. Now right click that icon in your panel and click preferences, a dialog box will open up and then goto Input Method

Installing Canon LBP2900b in Debian

I had already written an article on how to install the Canon LBP2900B in Debian when SysV init was  the norm but then systemd has taken over the Linux world by storm and only a handful of distro are hanging on to SysV or  had moved on to Runit. 

The current version of the canon capt driver is 2.71 that can be downloaded from the canon website.

before installing the canon driver we have to enable the support for 32-bit if you are the using 64-bit

Debian. The 64-bit driver needs the 32-bit driver installed for proper working otherwise it will only show printer is processing but it won't print.

Run the following commands.

[a] Enable 32-bit.

sudo dpkg --add-architecture i386 

sudo apt update

[b] Install CUPS

If you hadn't installed  cups already install cups and also along with other printer drivers.

sudo apt-get --no-install-recommends --no-install-suggests install cups  system-config-printer system-config-printer-udev printer-driver-gutenprint  foomatic-db-compressed-ppds 

If cups isn't running run the command 

sudo systemctl enable cups.service

[c]  Install the  Drivers

When installing  the  32 bit driver dpkg at first  will  not  install as there will be missing 32-bit libraries 

sudo dpkg -i cndvcups-common_3.21-1_i386.deb 

sudo apt install -f 

sudo dpkg -i cndvcups-capt_2.71-1_i386.deb

sudo dpkg -i cndvcups-common_3.21-1_amd64.deb

sudo dpkg -i cndvcups-capt_2.71-1_amd64.deb

[d] Edit the /etc/init.d/ccpd 

After installing the drivers edit the edit the /etc/init.d/ccpd file with the following info below the 

#!/bin/sh

### BEGIN INIT INFO
# Provides:          ccpd
# Required-Start:    $local_fs $remote_fs $syslog $network $named
# Should-Start:      $ALL
# Required-Stop:     $syslog $remote_fs
# Default-Start:     3 5
# Default-Stop:      0 1 2 6
# Description:       Start Canon Printer Daemon for CUPS
### END INIT INFO

run the following command

sudo systemctl cups restart

sudo /etc/init.d/ccpd start

IMPORTANT: systemd maps the `/etc/init.d/ccpd` script that comes with the printer driver package to the name `cppd 

[e] Create a ccpd2 unit file 

 create a file called ccpd2.service in /etc/systemd/system  with the following content

[Unit]
Description=Printer daemon for Canon printers
Requires=cups.service
After=cups.service

[Service]
ExecStart=/usr/sbin/ccpd
Type=forking

[Install]
# To run the daemon always when the system is up
#WantedBy=multi-user.target
# To run the daemon when a printer is attached
WantedBy=printer.target

Now run 

sudo systemctl enable ccpd2.service 

sudo systemctl restart cups.service

[f] Register the printer in the system

sudo lpadmin -p LBP2900  -m CNCUPSLBP2900CAPTK.ppd  -v ccp:localhost:59687  -E 

[g] Printer port definition 

sudo ls  /dev/usb/

[h] Registering the printer in ccpd service

sudo ccpdadmin   -p LBP2900 -o /dev/usb/lp0 

sudo ccpdadmin

[i]  Restart Cups and ccpd service

sudo systemctl restart cups.service

sudo systemctl restart ccpd2.service

[j] setting our printer as default 

sudo lpadmin -d LBP2900

Resart your computer make sure the printer the connected during boot so it can be recognized to avoid any hiccups.

To check the status run the following command 

captstatusui -P LBP2900 

  

It should show "Ready to Print" then it means you have correctly installed your printer. 

If the captstatusui reports a socket error then run the following commands 

sudo systemctl stop  cups.service

sudo systemctl start cups.service

sudo /etc/init.d/ccpd restart
