If you don’t own a printer, the alternative is to go to a reprographic centre whenever you need to print or scan something. While this is not a big deal if you only do that rarely, it is not practical for people who need to print regularly. The cost of printing from a reprographic centre will add up quickly and will cost you more than owning and running a printer pretty fast. Not to mention the inconvenience of going down to a shop. Therefore, the answer is, yes, buying a printer is worth every penny if you print every once in a while.
