Does that mean I should NOT be updating the kernel?
thanks!
Printers are supported via CUPS rather than a "kernel driver" as such, CUPS is a printing subsystem used on both Linux as well as MacOS. So it would be a CUPS driver that would talk to the CUPS subsystem. Therefore either way, updating the kernel would not effect the CUPS driver for your printer.

Thanks, everyone!!
Just resurrected this post to ask a quick question - if I keep updating kernel over a long period of time, will I eventually encounter a problem with my hardware becoming too "old"?
Considering that my hardware is relatively new (like machines purchased brand new 2-3 years ago) - when can I expect that obsolescence to happen? Or should I even worry about it?
Cheers!

Of course it depends on your hardware, but eventually it may indeed happen if the kernel stops support for certain hardware, an uncommon occurrence that usually only happens for obscure or very little used hardware. However I would imagine that this would be a *long* way down the line for you, almost certainly long after you've moved on to new systems. So, don't worry about it.

It isn't always a question of support being explicitly withdrawn. Old computers sometimes have quirky ways of doing things which may not agree with some coding change that was made in the kernel for presumably good reasons and that doesn't cause problems for anyone else. For example, I can't boot my HP desktop with kernels later than 4.13 unless I patch the code. There is a small change in the way memory is mapped, introduced as a simplification (according to the comment attached to it), that causes the kernel's acpi driver to crash on my hardware. For Crux and LFS, this is an annoyance rather than a problem; they both require a hand-built kernel so I can reverse the change in the code before building. And Debian Stretch still uses the older 4.9 LTS kernel. But one day this machine won't work any more and I shall have to fork out for a new one.

But is there a good reason to use a kernel later than 4.9 on your Desktop?
Distro's that stress stability will always be available without the latest in kernels.

My Desktop distro LMDE (Mint) was only recently upgraded from 3.16 to 4,9 a few months ago.
I'm not expecting later kernels to be offered for at least two years.
Even then, I'm not forced to install them.

I like to use a new release's native kernel. It feels a bit like cheating not to. And if you don't use a recent kernel, then you need to use an LTS kernel that will have all the recent security fixes backported into it.
