My Office Suite is LibreOffice and as far as I’m aware that’s Linux compatible
It is very much compatible, haha. And usually comes pre-installed as the desktop office suite in many distros like Ubuntu and Debian that ship the Gnome desktop environment pre-installed.
but would my ISP be impacted by Linux then?
It should not be impacted at all. :)
The simple aspect of my printer being compatible didn’t come to mind at first
If you install any popular beginner friendly distro (like the ones I recommended) everything should work out of the box and it is very unlikely that any extra drivers need to be installed. For example on Archlinux no printing programs/services and drivers come pre-installed or enabled.
So do not worry at all, if your laptop cover the main requirements, the distro should handle the rest automagically. If you have any more questions you can talk to me directly here on Lemmy, or we can figure something out.
One thing though, Mint is based on Ubuntu which itself is based on Debian. But it doesn't really matter.
Since you are going to check what software you need/want for your new Linux device, you can always fill the gaps with Flatpaks on Flathub, these are meant to be universal packages for every Linux distro and usually you can find there the packages that your distro does not package natively. You can even find proprietary software like Discord and such.
And again, if you have any more questions be sure reply or send me a message directly her eon Lemmy.
