I have a Lexmark CX317dn printer connected by USB that used to print almost anything in the blink of an eye. Since upgrading to Ubuntu 22.04 the printer has slowed to a snail’s pace. A single page PDF file with no graphics takes a couple of minutes to print. A two page email file (Thunderbird) took nearly 5 minutes. A simple one line text file took 60 seconds to print.
I have also noticed that Firefox taxes about two minutes to stabilize after starting up. (Chrome starts up much faster, but is still slower than before)
I am running Ubuntu 22.04.6 on an intel I7-9700K with 32GB RAM. I have a 500GB SSD for my system files and a 2TB HD for my home directory. I have performed all of the updates and my system, inlcuding the Lexmark drivers) is current.
Any help solving this problem would be greatly appreciated.
Have you updated UEFI firmware & SSD firmware to latest available?

Post this for your system, I use Kubuntu and no snaps on i5-6500 from 2017:
fred@z170-noble:~$ systemd-analyze
Startup finished in 4.281s (kernel) + 4.133s (userspace) = 8.414s
graphical.target reached after 4.120s in userspace.
Then this Only need to post top 5 items or so and start reviewing what may be slow:

Which are you using? Not sure when ipp-usb became standard.
ippusbxd is decidedly sub-optimal. Even its author would support your removing it from your system.
It has been replaced by ipp-usb in later editions of Ubuntu.
ippfind
I only know to reinstall ipp-usb, just in case not installed. My 24.04 says newest installed.
sudo apt purge ippusbxd
sudo apt install ipp-usb sane-airscan
This is interesting: I have a virtual system running (yes, it’s true) Windows XP. Printing a Word document from Windows virtual system is almost instantaneous and printing a pdf file from Windows takes about 10 seconds.
