How to Setup Canon LBP2900B Printer on MacBook Pro and MacBook Air
I have been using this old printer from a very long time which used to work fine on macOS Sierra but today it started giving problems on my MacBook Pro which is running on macOS Mojave 10.14.2. After this recent macOS update, it fails to detect the printer and stuck at the print dialog box.
If you are also on the same track who are looking to install Canon LBP2900B drivers patch on macOS Mojave, then you are at the right place. This article will provide you detailed steps to fix LBP2900B printer drivers problem on MacBooks.
Technically LBP2900B drivers for macOS is not available even on the official Canon website. But still, we can set-up the printer using LBP3000 drivers and applying a simple patch over it. Don’t worry, this process is very simple if you follow the below steps carefully. Here is how you can install Canon LBP2900B printer drivers on MacBook with latest Mojave update.
Step 1: Uninstall Old Printer Drivers
I order to avoid conflicts with the old printer drivers, you have to first delete them completely from your device. To uninstall the current printer, click on Apple icon on the top left corner and select System Preferences…
You will now see a lot of system options and you need to click on Printers and Scanners icon.
Select the old printer from the left side printers list, click on – button and select Delete Printer to delete your existing printer.
After deleting all unused printers, restart your Mac for the changes to take effect.
If you have any unused or duplicate printers in the list, make sure you delete all of them to be on the safer side. But double-check you are not uninstalling scanners or other working printers accidentally.
You need to be very careful while removing the printers if you have more than one printer or scanners installed on your device already.
Step 2: Download and Install CAPT Printer Driver & Utilities for Mac V10.0.0
Open Canon official website to download CAPT Printer Driver & Utilities for Mac V10.0.0. The drivers and utilities listed there is actually for Canon LBP3000 printer but don’t worry, we’ll apply a patch to make it compatible with LBP2900B printer.
Once you accept the terms and conditions checkbox, the download button will be activated. Clicking on it will start downloading mac-capt-v1000-uken.dmg file and you have to save it on the desktop.
Double click the file to mount and open the disk image. You will see two folders named Documents and MacOSX. Inside MacOSX folder, double click on Canon_CAPT_installer.pkg file to install the package contents.
Now you have successfully installed the required drivers of LBP3000 printer (Yes, not actually for LBP2900B printer). So you need to apply the below patch to correct this model number mismatch.
Step 3: Apply LBP2900B Patch for macOS Mojave
After installing CAPT driver and utility, you need to now apply the patch to make it work on Mojave update. First, download the patch canon_lbp2900b_patch_mojave.zip and extract the files on your desktop.
Now from the Finder menu, select Go and click on Go to Finder…
Under Go to the folder: text field, paste this path /Library/Printers/Canon/CUPSCAPT2/Bidi and click Go.
From Desktop, copy captmoncnab3 file from the extracted files of canon_lbp2900b_patch_mojave.zip and replace it inside the Bidi folder. Since you are replacing a file in System folder, you will be asked to enter the Administrator password.
Again under Go to the folder: text field, paste the following path /Library/Printers/Canon/CUPSCAPT2/cnaccm and hit Go.
Now copy the file CnAC28B9.DAT from already extracted patch files and replace it in cnaccm folder. After replacing these two files carefully, reboot your Mac and proceed to next step.
Key Points:
- Carefully replace both captmoncnab3 and CnAC28B9.DAT files in cnaccm and Bidi folders respectively. Even a minor mistake while replacing these files will not apply the patch correctly.
- Enter your Administrator password while replacing the patch files.
- You can unmount the disk and delete both canon_lbp2900b_patch_mojave.zip and mac-capt-v1000-uken.dmg files from the desktop after applying the patch.
- Rebooting your MacBook is optional but highly recommended.
Step 4: Setup Canon LBP2900B Printer on your Mac
After applying the patch, now it’s time to setup LBP2900B printer on your Mac machine. This step is very simple and straight forward.
To setup Canon LBP2900B printer on Mac:
- Power on and connect your printer to MacBook using a USB cable.

Conclusion for Canon LBP2900B Drivers on Mac Mojave
Despite the popularity of Canon LBP2900B printer, the drivers for the latest version of macOS is not yet available in Canon official store. The only possible and working solution to configure Canon LBP2900B printer drivers on macOS Mojave is by adding LBP3000 printer from System Preferences and applying a patch to make it compatible for LBP2900B model. You need to install a utility package and replace a couple of files carefully and your old Canon LBP2900B printer will start working on macOS Mojave.
But one thing I’m not sure is how it behaves when we connect both LBP3000 and LBP2900B models to the same device at the same. So this might be a real deal-breaker for people who own both models. If you have tried this case, please let us know how your Mac behaves in the comment section below.

Hi Amar,

Great tutorial. I was referring to this article back when I’m facing issue with Mojave. Now that I’ve upgrade my macOS to Catalina, it is not working anymore. Looking forward for a separated article for macOS Catalina from your end.

This method works on Catalina. The problem is SIP. You must disable SIP or re-sign captmoncnab3. Tested on Catalina 10.15.1, It works fine.
Download and install the driver for LBP3000 “CAPT Printer Driver & Utilities for Mac V10.0.1 [macOS 10.13/10.14/10.15” from here https://www.canon.com.au/laser-printers/laser-shot-lbp3000/support
Within the binary files
/Library/Printers/Canon/CUPSCAPT2/Bidi/captmoncnab3
and
/Library/Printers/Canon/CUPSCAPT2/cnaccm/CnAC28B9.DAT
replace all occurrences of “LBP3000” with “LBP2900”. You can use the free iHex software available on the App Store to do that. Don’t use a Text Editor. In iHex, use the search and replace all, do not forget to select the text for the search fields.

1) Mount Gatekeeper Helper.dmg;

Open the Terminal, copy and paste the command into it:
The code:
xattr -c ~/gtkhelper; chmod +x ~/gtkhelper
3) To run the script, execute in the terminal;
The code:
~/gtkhelper
4) Script Items:
1 – Turn off the SIP
2 – Turn on the SIP
3 – Turn off the SIP for a single application
4 – Self-sign application
5 – Exit
5) Choose the fourth item
6) Drag captmoncnab3 file (edited) to the terminal and press Enter
7) Close everything and restart the computer
