Say Goodbye to Printing Problems: How to Effortlessly Uninstall Canon Printer Driver in Ubuntu

Are you struggling to get rid of a stubborn Canon printer driver on your Ubuntu system? Whether it’s causing conflicts, you’ve upgraded your printer, or you simply want a clean slate, knowing how to uninstall Canon printer drivers in Ubuntu is essential. This guide will walk you through the process, providing clear steps and explanations to ensure a smooth and successful removal.

Why Uninstall Canon Printer Drivers?

There are several reasons why you might need to uninstall Canon printer drivers in Ubuntu:

• Driver Conflicts: Outdated or incompatible drivers can lead to printing problems, slowdowns, or even system instability.
• Printer Upgrade: If you’ve replaced your old Canon printer with a new one, you’ll need to remove the old driver to avoid conflicts and ensure proper functionality.
• Troubleshooting: Sometimes, uninstalling and reinstalling the driver can resolve printing issues.
• Clean Installation: If you’re starting fresh with a new Ubuntu installation, removing old drivers helps prevent conflicts and ensures a clean system.

Step 1: Identify the Canon Printer Driver

Before you can uninstall the driver, you need to identify its name. Ubuntu uses packages to manage software, and each driver has a unique package name. Here’s how to find it:
1. Open the Terminal: Press **Ctrl + Alt + T** to open a terminal window.
2. List Installed Packages: Type the following command and press Enter:
“`bash
dpkg -l | grep -i canon
“`
This command will list all installed packages that contain “canon” in their name. The output will look something like this:
“`
ii libcupsfilters2:amd64 2.1.0-1ubuntu1 amd64 CUPS filters for printing
ii libcupsfilters1:amd64 2.1.0-1ubuntu1 amd64 CUPS filters for printing
ii canon-mg5700-series-ppd 2.0.0-1ubuntu1 amd64 PPD files for Canon MG5700 series printers
“`
Look for the package name that corresponds to your Canon printer model. For example, if you have a Canon MG5700 series printer, the package name would be `canon-mg5700-series-ppd`.

Step 2: Uninstall the Canon Printer Driver

Once you know the package name, you can uninstall it using the following command:
“`bash
sudo apt-get remove
“`
Replace “ with the actual name you found in the previous step. For example:
“`bash
sudo apt-get remove canon-mg5700-series-ppd
“`
You will be prompted to enter your password to confirm the removal.

Step 3: Remove Leftover Files (Optional)

Sometimes, even after uninstalling the driver, some files might remain. You can remove these manually using the following commands:
1. Remove configuration files:
“`bash
sudo rm -rf /etc/cups/ppd/canon-*
“`
2. Remove printer queue:
“`bash
sudo lpadmin -x
“`
Replace “ with the name of your Canon printer.

Step 4: Restart Your Computer

After uninstalling the driver and removing any leftover files, it’s a good idea to restart your computer. This ensures that all changes are applied correctly and that the driver is completely removed.

Step 5: Verify Removal

After restarting, open the Settings app and navigate to **Printers**. You should no longer see your Canon printer listed. If it’s still there, you can try reinstalling the driver and then uninstalling it again.

Important Considerations:

• Backup: Before removing any files, it’s always a good idea to create a backup of your important data.
• Manual Removal: If you’re unable to find the driver using the `dpkg` command, you can try removing it manually by locating the driver files and deleting them. However, this is not recommended for beginners as it can lead to system instability if done incorrectly.
• Reinstall Driver: If you need to use your Canon printer again, you can reinstall the driver by searching for it in the **Software & Updates** app or by downloading it from the Canon website.

Beyond the Basics: Troubleshooting and Additional Tips

• Driver Conflicts: If you’re experiencing driver conflicts, try disabling other printer drivers temporarily to see if that resolves the issue.
• System Updates: Keep your Ubuntu system updated with the latest software releases to ensure compatibility with your printer drivers.
• Canon Website: For specific instructions and troubleshooting tips for your printer model, visit the Canon website.
