I don't own a printer myself
But my small-ish company owns several, and in my country it is basically essential...
A major reason to have a printer here, is that if you do ANY, and I mean ANY business, you need to file a electronic form with the government, and print a physical copy.
The reason for this, is that we have a transportation tax, and if the road police stops you, you must have the printed document on you to show to the cop the goods you are transporting had the tax paid.
Weirdly a lot of people DO NOT know that it is the road police that is the intended readers of the document, so the information that is relevant to them is often wrong (people file price, tax, etc... correctly, and then put random values in volume amount, weight, size, registration plate of vehicle, etc...) then they get surprised the police seizes their stuff.
And many just don't print it, and assume sending to the digital document is enough. (it is not, a cop in the middle of nowhere might not have internet to check on the official servers the document, and thus he will want the paper copy that he can read with a flashlight)
