The instructions for installing Canon LBP2900 Printer on Ubuntu 20.04 remain pretty much the same as given in an earlier post about Installing Canon LBP2900 Printer on Ubuntu 16.04. The few differences seen this time around are the following:
1) Newer version of LINUX-CAPT-DRV-v271-UKEN: Download link as mentioned on the Canon Support page.
The tar ball includes 64-bit installers: cndrvcups-common_3.21-1_amd64.deb & cndrvcups-capt_2.71-1_amd64.deb (also includes rpm files & 32-bit versions).
2) Depdency on libglade2-0:
$ sudo apt-get install libglade2-0
3) Workaround for CAPT 64-bit OS issues linking to 32-bit libraries:
As mentioned in the earlier post, there are certain dependencies for CAPT running in 64-bit OS in linking to 32-bit libraries. Even though, the two deb files (mentioned above) get installed without the dependencies, peculiar behaviour/ error message is seen when the dependecies are missing. On the final step to View Status of printer on captstatusui, an error message is shown: "Check the DevicePath of /etc/ccpd.conf".
The solution to the problem is to simply check the missing dependencies:
(Check for error messages such as not executable, not found, etc.)
$ ldd /usr/bin/captfilter
$ ldd /usr/bin/capt* | sort | uniq | grep "not found"
In case of error install the missing dependencies:
$ sudo apt-get install libc6:i386 libpopt0:i386
$ sudo apt-get install zlib1g:i386 libxml2:i386 libstdc++6:i386
4) Follow the remaining instructions of the earlier post:
=> Install CAPT printer driver (downloaded .deb files mentioned above)
=> Add printer to the system: (Command line lpadmin or system-config-printer or UI System Settings > Printers):
=> Add printer to ccpadmin
=> View status of printer on captstatusui (should show "Ready to Print" if installed correctly)
=> Finally, print test page to finish!
