Because printing in Linux both works and is supported and not supported and hope that there are drivers and they work.
For example, I have a brother printer and in both arch and Ubuntu/mint the printer worked out of the box. But I was missing features like double sided printing. So I had to download drivers for it.
In arch the drivers were on the AUR, so I was printing is seconds.
In Ubuntu/mint they weren’t in my package manager, so I had to go to brother’s website and hope they had drivers. Brother did and while it took a bit it did work too. No worse than windows.
Honestly if you are looking to move to Canada, they are desperately looking for Nurses especially out in Eastern Canada like Nova Scotia and New Brunswick.
Immigration is being tightened right now, but if you already have a degree and looking to get recertified here its a good starting point.
