@zwastik, The cndrvcups-common-lb , cnrdrvcups-lb and cndrvcups-lb packages provide a different sets of drivers than capt. All of those three provide the UFR II drivers for Canon printers, which is different from the CAPT drivers.
As replied by LoneWolf, the maintainer of all the other three packages in 2016 to a similar comment,
'capt-src also uses cndrvcups-common, though another version then this package. If you really need both capt & UFR II AL drivers,you're the first in 5+ years.'
and
'While both cndrvcups-capt[1] and cndrvcups-lb use cndrvcups-common, they are targeted towards a specific version . latest cndrvcups-lb 3.40 uses cndrvcups-common 3.80 , latest capt 2.71 uses cndrvcups-common 3.21.1 . There have been times that they shared the same version, but that is rare. Using a different version then the one canon supplies in the driver download doesn't work. To allow capt-src to be installed alongside cndrvcups-lb or cndrvcups-lb-bin , the 3 maintainers would need to decide on a mechanism that allows multiple cndrvcups-common versions to be installed at same time. [1] cndrvcups-capt is the name canon uses for the capt printer driver'
So, they are not meant to be installed at the same time, if one works for you use that one, otherwise try the other one. Maybe I should add them as conflicts for this.

Do not expect this driver to work in the near future if Canon doesn't release a new version soon. This driver is from 2017 and the GCC environment started deprecating a lot of stuff used by this driver. Please, ask for better Linux support to Canon.
Do not flag this package out of date if there's no new version available. That's bad community behavior. A comment telling about the issue is enough.
If your machine uses the x86_64 arch, the multilib pacman repo will be needed for this driver: https://wiki.archlinux.org/index.php/Official_repositories#multilib
For an alternative 100% open source driver although not official by Canon, go to: https://aur.archlinux.org/packages/captdriver-git/

Re: driver deprecation - the CUPS creator opened this issue to discuss how to handle old devices: https://github.com/apple/cups/issues/5271
From one of his comments: "Before we drop PPDs, we will be working with developers to create those printer applications (particularly Gutenprint), and will likely end up creating our own printer application (based on the existing ippserver sample code) to support existing PostScript and CUPS raster drivers. So the goal is definitely not to leave people SOL, but rather to plan for a future where we aren't limited by the capabilities of the past."

Now you'll see this warning message: lpadmin: Printer drivers are deprecated and will stop working in a future version of CUPS.
Not sure what this will mean for the future with this driver.
