Ubuntu was planning to ship the CUPS printing stack as a Snap in 23.10 — but after several months of testing, its changed its mind.
Accordingly, a DEB-based printing stack will feature in Ubuntu 23.10 “Mantic Minotaur” and in Ubuntu 24.04 LTS. Switching to the CUPS Snap will now aim to take place during the Ubuntu 24.10 development cycle.
From what I’ve been reading on the internet, mostly from other people, Ubuntu is leaning heavily into making everything a Snap. Any official flavour of Ubuntu is expected to follow this. Other Ubuntu-based distros, like Mint, are avoiding Snap as far as possible. So, there’s options for anyone that doesn’t like Snap at least.
