Catalina Driver for Canon LBP 2900

Fortunately that is possible.The main problem you must be facing is the 'captmoncnab3 is damaged and must be moved the bin'

this can be bypassed by following steps

1) Remove old printers in system preferences ->printers and scanners

2) Download CAPT Printer Driver & Utilities for Mac V10.0.0

3) Install it

4) Then download the patch

5) Unzip the file and replace the captmoncnab3 file with captmoncnab3(patched) file in the zip by going to finder path /Library/Printers/Canon/CUPSCAPT2/Bidi/captmoncnab3

6) Then replace the CnAC28B9.DAT file in finder path with CnAC28B9.DAT(patched) in finder path /Library/Printers/Canon/CUPSCAPT2/cnaccm

7) Connect to your Canon LBP 2900/2900b & Go to System preferences -> Printers and Scanners and add the printer using Canon LBP3000 CAPT (UK) driver software

8) Now when you try printing you see the dialog box 'captmoncnab3 is damaged and must be moved the bin' so copy the pathname of the patched file captmoncnab3 that we replaced in step 5 and go to terminal

9) After opening terminal window copy this command xattr -cr /The pathname that you copied (be careful of the two "/" after you copy) example : xattr -cr /Library/Printers/Canon/CUPSCAPT2/Bidi/captmoncnab3

10) Restart your system

11) Try printing a file and it will work

So i just throw the printer away... This is shocking.... Apple please do something and make it work with a patch or something

You have the following options:

• Revert to an earlier macOS version where your printer still worked

from you Time Machine or clone backup. Never apply any updates/upgrades

ever again.

• But a new printer that supports OS agnostic printing, i.e. WiFi/Airprint or Postscript
• Complain to Canon for their lack of 64 bit support. Unlikely that they will since it

they want to sell new printers and not support old ones.

There's driver for LBP 3000 supporting Catalina - https://www.canon.ru/support/consumer_products/products/printers/laser/i-sensys_lbp3000.html?type=drivers&language=ru&os=macos%2010.15%20(catalina)

Probably someone knows how to adapt it for LBP 2900 like it has been done for all previous Mac OS versions?

You can use this guide. I tried and it's helping me to solve:

1/ First at all, you must TURN OFF SIP (google for this)

You will use the driver for Canon LBP3000

2/ Download this file: https://www.fshare.vn/file/TGIZ6K5MG5ZE. Run it, install.

3/ Download this file and unzip: https://www.fshare.vn/file/BSOUYZRKCO36?token=1573114484

4/ Open FINDER, press Command + Shift + G and type: /Library/Printers/Canon/CUPSCAPT2/Bidi/

Copy 2 file that unzip in step 3. Type your password

5/ Again, open FINDER, press Command + Shift + G and type: /Library/Printers/Canon/CUPSCAPT2/cnaccm

Copy 2 file that unzip in step 3. Type your password

RESTART your macbook

6/ Add printer: Open System Preferences, chose Printer & Scanners. At Printer & Scanners click +. You will see Canon LBP2900, you chose driver Canon LBP3000 CAPT (UK) and click Add.

Everything done. Try to print (It show Canon LBP3000)

Sometime you will get trouble, try again all step. I hope it will help.

Canon didn't support this printer for Mojave as well but there was a solution with this replacing the original captmoncnab3 and CnAC28B9.DAT files.

For Catalina this method doesn't work.

So we need someone to fix it. THX in advance!

This method works on Catalina. The problem is SIP. You must disable SIP or re-sign captmoncnab3. This is done by a script from here: rutracker.org/forum/viewtopic.php?t=5764352 In the script, select item 4. 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.

reboot Mac

Download Gatekeeper Helper.dmg:

https://drive.google.com/open?id=1Syls0VNvXS5ckNtKJ43-jdH8oapOAwXV

or

https://rutracker.org/forum/viewtopic.php?t=5764352

1) Mount Gatekeeper Helper.dmg;

2) Copy the script file to the user folder. (In the Finder panel on the left is the folder with your user name)

To do this, just drag it there with the mouse.

You need to remove the attributes assigned to the file when writing to the file system disk and make the script executable on the system.

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

8) Connect the LBP2900 to the USB Port and in the System Preferences add a Driver for it specifying the Canon LBP3000 Driver.

Enjoy

Ok, here are two patched files. But this is unlikely to solve the issue of SIP.

macOs Catalina 10.15.1 driver mac-capt-v1001-uken.dmg

К сожалению, идей нет. Если все пункты из инструкции выше сделаны, то подсказать больше не смогу. Единственное, у меня установлена последняя версия Xcode, возможно в ней есть недостающие компоненты. Если вы читали форум на рутрекере (страница загрузки скрипта) то там есть информация, что в каталине есть изменения и часть старых команд в терминале не работает, у меня таких проблем не было, всё заработало сразу, никаких дополнительных инструментов кроме Xcode нет.

Вам нужно скачать и установить xcode developer tools.

Для этого в терминале запускайте команду xcode-select --install

После установки опять в терминале:

~/gtkhelper

Выбирайте пункт 3 и перетаскивайте файл captmoncnab3 в терминал. Жмёте Enter, потом спросит пароль, вводите и опять Enter.

Всё закрыть и перезагрузить.

Дальше устанавливайте драйвер принтера через Системные настройки-Принтеры и сканеры

sorry, when I complete step 7, there is a message - “captmoncnab3” is damaged and can’t be opened - and two options of "show in folder" and "ok". nothing can be changed. I cann't go further. thank you.

Canon won’t support Catalina so your options are to replace or connect to a Windows machine with sharing enabled over the network. Good luck.

К сожалению, все равно такую ошибку дает, хотя все прописал и без ошибок)

В чем может быть проблема?

Быть может на этом этапе что-то не так?

No fix, no point hoping for one. Buy Brother. Works plug and play, no hassle.
